The Congress had as its theme “Organic Viticulture - Quality, the key factor to success” and the importance of variety choice, soil management, plant protection and biodiversity for organic wine quality were discussed at this congress. An overview of organic viticulture world-wide was also given. The 6th International Organic Viticulture Congress in Basel is in the tradition of the organic viticulture congresses, the first of which was held in 1985 in Geisenheim (D), organised by the German organic wine growers’ association Ecovin. At this congress, the German standards for the production of organic grapes, grape juice, wine and champagne were launched. The 4th congress in Würzburg 1994 dealt with marketing, market development and the labelling of organic wine. The fifth congress, held in Bad Dürkheim 1995, was the first one to be organised by all German organic producer organisations and by Stiftung Ökologie & Landbau, and it was also the first international organic viticulture congress. It dealt with questions of soil management and wine quality as well as farm management aspects. The proceedings of the 3rd, 4th and 5th conference were published by Stiftung Ökologie & Landbau.

The cultivation of this fruit species, however, is delicate in humid climates and experience to advice growers still lacking. Definition of the problem: Developing and introducing a new culture of table grapes under Swiss climatic and economic conditions. Project aims: Study of the possibility to produce organic Table Grapes under Swiss climate and economical conditions Methodology: On farm trials, consumers taste test, variety testing and plant protection strategies in replicated field trials. Results, conclusion, state of the art: A quality organic production of Muscat Garnier and Muscat de la Birse has been established. However, protection from rain is necessary in order to improve visual quality. However more and different cultivars are needed to cover modern consumer demand. type: Project description type: NonPeerReviewed identifier: {Project} Aufbau einer Schweizer Bio-Tafeltrauben Produktion.

Alternatives with mulching methods or weed burners do satisfy only in specific conditions. Tillage systems that provide sufficient, reliable weed competition control over a large range of soil and site conditions and for low costs are still to be developed. In order to ensure a sufficient supply of water and nutrients in orchards it is necessary to regulate weed growth in the in-row strips. In organic fruit growing this is achieved by keeping the soil open with special tillage equipment (very costs intensive), or by mulching with organic material, such as bark, wood shavings and straw (high costs and high deposition of potassium, which increase the risk of bitter pit) or water permeable synthetic ground covers. The mulching systems can considerably increase mice damage and are suited only for specific soil and site conditions. Project aims: i) to develop and validate an alternative system (Sandwich System) that allows a sufficient supply of water and nutrients, but needs a lower input of resources; ii) comparing growth and yields of the trees under Sandwich-System versus usual tillage over the whole width of the tree strip. Methodology: The systems were compared in 7 apple cultivars. Two repetitions in each cultivar. Collected data was yield, trunk perimeter, nutrients contained in fruits and leaves (T-Stage). For the statistical analysis we used the Program JMP 4.02 (SAS incorp.), ANOVA model; variety, System, repetition, variety*system, variety*repetition, system*repetition Results, conclusion, state of the art: - No significant differences in the yields of both systems were observed (annually and accumulated) - The accumulated vegetative growth of the trees was significantly higher under sandwich-system (11%). - In leaf and fruit analysis for mineral uptake (from 2000 to 2003) there was no consistent tendency to be found that could indicate any better or less optimal nutrient availability between the two systems. From totally 74 data sets, there were 14 significantly different but of a low practical relevance. - Due to its low costs (60 % cheaper than good usual tillage devices) and its high performance (up to 9 km working speed) the Swiss Sandwich–System is an interesting alternative to the usual tillage devices. - If with the Sandwich System, the establishment of a low growing vegetation in the centre aisle is difficult (as in the case of our investigation), it becomes necessary to mulch the central green strip 1-3 times a year. - Due to passive tools, only, the Sandwich acts very softly to soil structure. - Together with the industry (Santini and Braun, CH-Sulgen) we could develop a now commercially available tillage device for the Sandwich-System Our results show, that with the Sandwich System tree performance is equal to whole-width tillage. The advantages are: i) about 60 % cheaper than usual good tillage devices, ii) high working speed (6-9 km/h); iii) soft to soil structure due to passive tools, only. type: Project description type: NonPeerReviewed identifier: {Project} In-row strip, sandwich system, weed management: Baumstreifenpflege im Obstbau.

However with older trees it doesn’t work sufficiently in the inner parts of the tree. Also the device must be used very softly in order to prevent physical and physiological damages to the trees. Definition of the problem: In several countries organic apple growers can use lime sulphur for flower thinning to regulate the crop load on the apple trees. In Switzerland, however, no spray product is allowed for early crop load regulation to control bi-annual bearing in organic apple growing. This is a key problem for organic apple growers in terms of high labour costs for manual thinning and in terms of high difficulties to achieve good quality fruit every year. Target group: Organic apple growers Methodology: On-Farm trials. Partly, e.g. to check phytotoxic effects in advance, also greenhouse experiments. We are testing different molasse and oil products using not-thinned, rope-thinned and lime-sulphur-thinned treatments as reference standards. Results, conclusion, state of the art: We found good thinning potentials with molasses (vinasse) products and emulgated oils. However, still a lot of optimizations need to be investigated. type: Project description type: NonPeerReviewed identifier: {Project} Crop load organic apple: Biologische Behangsregulierung im Kernobstbau.

Yield security in organic vine production is not sufficient due to high disease pressure on sensitive cultivars. The reduction of copper applications has a high priority – also for reasons of consumer acceptance. Additionally different management practices for weed control, plant nutrition; plant formation and vine-making (oenology) are not optimized on a level as it is the case in conventional production. Project aims: Develop or and test plant protection and management strategies to increase yield security of organic vine growing. Improvements in organic oenology techniques. Methodology: Trials in precision trials and on On-Farm level in Switzerland, France, Italy and Spain. Microvinification. Results Different new natural spray products to prevent diseases were tested. Partly with positive effects. Novel prognosis models can contribute efficiently to apply more precisely and less organic fungicides (in particular copper). The application of modern software to predict the infection risk of diseases has been shown to be helpful in terms of better timing of the applications. Consequent leaf-thinning of the grape zone can reduce disease pressure. Some new spray products (clay powder, plant extracts and resistance inducers) are tested. New systems of the alleyway-management with specific cover plants are tested, also for arid zones. type: Project description type: NonPeerReviewed identifier: {Project} Organic vine growing: Erhöhung der Ertragssicherheit und Optimierung der Pflegemassnahmen im biologischen Weinanbau.

Until 2003 sales of organically produced berries were very low. Also table grapes, pome and stone fruit need support and promotion activities along the whole chain from farm to shelf. The aim of the project is to ensure a continuous delivery for Coop with an attractive assortment of organic fruit and berries. A nation-wide professional producers' network and a logistic system should be established. Between 2002 and 2005 the sales of organic berries at Coop rose by 371 %. Currently, special attention is given to table grapes, stonefruit and pears. type: Project description type: NonPeerReviewed identifier: {Project} Organic berry production: Förderung von Biofrüchten und -Beeren.

Definition of the problem: Consumers, retailers, producers and scientists, for different reasons are very interested at the question whether organically grown fruit tastes better and is heathier. Very little comparative data are available. Project aims: To analyse and compare different parameters of inner fruit quality (sensorial and health-related) from conventional and organic commercial fruit production. Methodology: In a field study including 10 commercial orchards that form 5 comparison pairs (conv./org) at 5 different sites in all important fruit growing regions of Switzerland fruit samples of cultivar Golden Delicous were picked and analysed. We measured: sensorial score, standard fruit quality (sugar, firmness, acidity); mineral content, content of polyphenols, vitamins, nutritional fibres. We also applied holistic methods such as picture forming methods, feeding preference tests with rats, self degradation tests. Since 2004 we also test the potential of the so called Gas Discharge Visualisation method (GDV; Kirlian Photography). Results, conclusion, state of the art: Regularly we found increased contents of polyphenols in organic fruit (10-20 % more). In half of the cases, sensory scores were better for organic fruit, case-wise also fibres and phosphorus content were higher in organic fruit. A “Vitality”-Index, derived from the picture forming method, was well in line with the standard quality and revealed repeatedly up to 60 % higher scores for organic fruit. type: Project description type: NonPeerReviewed identifier: {Project} Innere Qualität von Bioobst.

Preliminary research during several years with different oxidative substances and products (H2O2, per-acidic-acid, nitrite) and with Ozone did not reveal sufficient control. Among the variou apple storage diseases, Gloesporium sp. causes extraordinary difficulties with organic fruit compared with conventional fruit. This is due to the fact that organic fungicides sprayed against scab or powdery mildew have no effect on Gloeosporium spores. Thus, infection can cause very severe losses with up to 80-100 % with sensitive cultivars such as Topaz or Pinova. Currently the Gloeosporium disease can be partly controlled by post-harvest by immersion of the apples in 50-52 Degree Celius hot water. Although this method is approved by the organic standards and reliably prevents the spreading of the disease its disadvantages are i) high equipment costs ii) high energy consumption iii) pre-harvest infestation is not controlled and becomes visible after immersion. The project aim is therefore to develop alternative post- and pre-harvest methods to control Gloeosporium storage disease in organic apple growing. Methods applied are - Pre-harvest treatment with organic fungicides on the varieties Pinova and Topaz. - Post-harvest dipping in cold water electrolyte solutions. Hot water dipping is the reference treatment. Results Since 2004 we have had significant control success with the use of clay powder for pre-harvest control and with dipping in cold water electrolyte-solutions for post-harvest treatments. Both control strategies, pre- and post-harvest have to be verified and optimized. Additionally, the technical equipment for fruit dipping in electrolyte solutions has to be developed for practical conditions. type: Project description type: NonPeerReviewed identifier: {Project} Gloeosporium control: Kontrolle der Gloeosporium-Fäule bei der Lagerung von Äpfeln aus biologischem Anbau.

Lead of WP4: On-farm application and testing on innovative methods subject: Crop health, quality, protection subject: Viticulture subject: Biodiversity and ecosystem services description: Das Projekt EU-ORWINE befasst sich mit der Entwicklung umwelt- und verbraucherfreundlicher Herstellungsverfahren und rechtlicher Grundlagen. Der biologische Weinbau ist ein bedeutender Zweig der biologischen Landwirtschaft. Dennoch fehlen bislang in der EU Verordnung 2092/91, welche die rechtliche Grundlage des biologischen Landbaus darstellt, Richtlinien für die biologische Weinherstellung und für eine entsprechende Kennzeichnung von biologisch erzeugtem Wein. Dies führte dazu, dass eine beträchtliche Menge biologisch erzeugten Weines konventionell vermarktet werden muss. Darüber hinaus sind die in mehreren EU-Ländern von biologischen Anbauverbänden entwickelten privaten Standards zur Weinherstellung heterogen hinsichtlich erlaubter Zusatz- und Hilfsstoffe und deren Höchstmengen. Vor diesem Hintergrund ist es das Ziel des EU-Projektes ORWINE, rechtliche Rahmenbedingung für biologisch erzeugten Wein zu schaffen sowie Produktionsverfahren und Qualität biologischen Weines zu verbessern. Projeklaufzeit: 38 Monate (Kick-off Meeting Februar 2006, Udine) Projektziele: Identifizierung und Evaluierung derzeitiger Verfahren der biologischen Weinherstellung sowie deren Einflüsse auf Umwelt und Weinqualität. Identifikation von Nachfragemotiven biologischen Weines und des Marktbedarfs zur Entwicklung bedarfsorientierter Kennzeichnung und Kommunikationsstrategien. Entwicklung innovativer und dem Konzept des Biologischen Landbaus entsprechender Weinherstellungsverfahren unter besonderer Berücksichtigung von Reduzierungsmöglichkeiten des Schwefeleinsatzes bei der Weinherstellung zur Verbesserung der Qualität von biologischem Wein. Prüfung innovativer Weinherstellungsverfahren und deren Umsetzbarkeit auf Betrieben. Entwicklung eines Leitfadens für eine gute fachliche Praxis der biologischen Weinherstellung und von Empfehlungen für eine um Weinherstellungsrichtlinien erweiterte EU Verordnung unter Partizipation von Interessenvertretern. type: Project description type: NonPeerReviewed identifier: {Project} Organic viticulture and wine-making: development of environment and consumer friendly technologies for organic wine quality improvement and scientifically based legislative framework (EU-ORWINE).

Parallel dazu ist eine gewisse Verwässerung der ursprünglichen Ideen des Biolandbaus und der Integrierten Produktion zu beobachten. Die Konsumentinnen und Konsumenten verlangen aber immer mehr nach zumindest rückstandsfreien oder besser pestizidfrei produzierten Produkten. Diesem Wunsch nach pestizidfrei produzierten Äpfeln könnte nachgekommen werden, wenn alle systemstabilisierenden Massnahmen ideal kombiniert werden. Daraus resultiert ein Low-Input-Apfelanbau: ideale Standortwahl, resistente Apfelsorten, ökologische Elemente zur Förderung von Nützlingen und der additive Effekt von Biocontrolmethoden. Verschiedene Forschergruppen haben bereits zeigen können, dass systemstabilisierende Massnahmen grosse Vorteile bringen. In vielen Versuchen zeigte sich jedoch auch, dass die Schädlinge und Krankheiten nicht immer unter die Schadschwelle gedrückt werden können. Ergänzende Massnahmen sind nötig. Die biologische Regulierung (Biocontrol) würde sich in vielen Fällen anbieten: Blattlausräuber gegen Blattläuse, Granuloseviren gegen Wicklerarten, Bacillus thuringiensis gegen Frostspanner, Bacillus subtilis gegen Feuerbrand, andere Bakterienarten gegen Schorf. Bis anhin wurde aber noch nie geprüft, ob die Systemstabilisierung in Kombination mit Biocontrol zu einer ausreichenden und zuverlässigen Unterdrückung der Schaderreger führt. Ziel des Versuchs Ziel dieses Versuchs ist es, den zukünftigen Low-Input Apfelanbau ohne Pestizide mit den bestmöglichen systemstabilisierenden Massnahmen und in Kombination mit den modernen Biocontrolmethoden zu prüfen und den Produzenten zu demonstrieren. Der Versuch soll zudem aufzeigen, wo die systemstabilisierenden Massnahmen und Biocontrolmethoden nicht ausreichen. Als Vergleich wird der aktuell gängige High-Input-Bio- und IP-Apfelanbau auf gleichzeitig gepflanzten Parzellen auf Betrieben in verschiedenen Regionen der Schweiz herangezogen. Konzeption des Versuches Ein Kernversuch von rund 1 ha (quadratisch, um Randeffekte zu vermeiden) ist im Winter 2006/07 am FiBL gepflanzt worden. Die Anlage wurde ganzflächig mit den nach neuestem Wissen ausgewählten Elementen der Systemstabilisierung versehen. Damit ist nur ein Systemvergleich und keine Einzelkomponentenanalyse (z.B. Hecken, Einsaaten, Baumstreifenbegrünung) möglich. In zwei Wiederholungen werden zwei Verfahren getestet (4 Blöcke, Verfahren diagonal gegenüberliegend). Die zwei Verfahren sind: „Systemstabilisierung“ und „Systemstabilisierung plus Biocontrol“. Als Biocontrolmethoden kommen alle für den Apfelanbau tauglichen Produkte in Frage: Granuloseviren gegen Apfelwickler, Bacillus thuringiensis gegen Raupenschädlinge, Marienkäfer oder Ohrwürmer gegen Blattläuse, Raubmilben gegen Spinmilben etc. Dabei werden die Biocontrolprodukte, wie in der aktuellen Diskussion um deren Zulassung in der EU, nicht als klassische Pestizide definiert. Dank der beiden Verfahren kann der additive Effekt der systemstabilisierenden Massnahmen und der Biocontrolmethoden quantitativ erhoben werden. Dies ist weltweit der erste Versuch dieser Art. Die Referenzparzellen liegen nicht innerhalb Modellanlage, weil sonst eine gegenseitige Beeinflussung nicht ausgeschlossen werden kann. Für den quantitativen Vergleich der im Versuch erhobenen obstbaulichen und ökologischen Daten werden Erhebungen in möglichst benachbarten Praxisobstparzellen erhoben. type: Project description type: NonPeerReviewed identifier: {Project} SFS: Pestizidfreie Apfelproduktion dank Systemdesign und Biocontrol (SustainableFruitSystem).

Such methods need to be developed. Since 2005 organic fruit and wine producers have to use plantlets from organic nurseries. Currently, prices for these plants are higher and their external quality is lower than that of conventional plants. Therefore organic growers and nurseries have expressed their urgent demand for improved production techniques to reach an “as-conventional” quality of the organic plantlets. As part of the project on-farm research trials are carried out on: i) different fertilization concepts; ii) substitution of ramification-hormones (manual methods or natural substances); iii) use of mycorrhiza; specific soil bacteria; iv) optimization and innovation of plant protection; methods to improve weed control; and between-row management (cover plants); v) tests on rootstock production; vi) elaboration of quality criteria for organic tree and grapevine plantlets Regular consultation and follow-op of organic tree nurseries are carried out. Results -Fertilization with high levels of nitrogen in the spring did not result in the best quality trees. -Firsts results with soil bacteria products show that it might be possible to work with less nitrogen fertilization. -Use of foliar fertilizers did not improve tree quality. - So far, the best substitute of ramification hormones is the mechanical method (Pleuzen). - Soil management control between rows: Covering the soil with organic material (China straw) or with plastic foil (Mypex) and sowing with annual legumes or Phacelia represent practical possibilities. type: Project description type: NonPeerReviewed identifier: {Project} Organic fruit tree and grapevine nurseries: Produktionsaufbau und Qualitätssicherung für Bio-Jungbäume und Bio-Jungreben.

No rare there appropriate breeding programs on-going. Thus, knowledge is very scare. Definition of the problem: Pipfruit as apple and pears are difficult to produce organically. A key disease is scab (Venturia sp.); but also susceptibility to leaf spot disease, monilia, sooty blotch disease, aphids, insects, biennial bearing, cracking etc. are major problems to overcome with organically approved methods and products. Additionally, also organic pipfruit have to achieve the high and significantly increased expectations in terms of outer and inner quality. Project aims: To find apple and pear cultivars suited for organic production. Methodology: Precision trials are planted at FiBL in Frick (20 cultivars per series in an in-out-system; trees are planted in two blocks: “very extensive” with 3 x 2 trees and “with usual care” 2 x 5 trees. Tree-wise we measure yield, tree vigour, disease and aphid damage, standard fruit quality, storage ability. Each year we organize several sensorial blind tests with larger consumer groups. Some advanced cultivars are also under On-Farm observation at 5 sites in organic orchards of all important growing regions of Switzerland. Trials with pears have started in 2005 only (10 cultivars and selections, planted at FiBL and Aubonne, each with two blocks of 5 trees per cultivar). Results, conclusion, state of the art: Regularly we publish a list of recommended apple cultivars suited for organic production and professional retail. New concepts for marketing and variety introduction could be derived from these activities (e.g. the “Taste-Group Concept”; or the “Variety Team” concept). Thus, the project had and still has a clear and very direct influence on production and marketing of the organic apple branch in Switzerland. Pear trials were started in 2005. type: Project description type: NonPeerReviewed identifier: {Project} Organic Pipfruit: Sortenprüfung Kernobst für den biologischen Anbau.

Their potential is still behind the standard but highly susceptible varieties. Organic viticulture in a humid climate like in Switzerland is difficult to achieve, mainly due to the high disease pressure of Plasmopora viticola and Unicula Necator. Beside improved natural plant protection spray strategies and products, we put emphasis on disease resistant cultivars to overcome the problem. Project aims - To find grape vine cultivars showing at the same time high wine quality and disease resistance. Methodology - At Frick, under 100 % organic conditions we carry out a “Top-Ten-Trial” with the 10 most promising cultivars in 4 replicates at 50 vine plants each. Thus, there is enough must available to carry out a proper vinification. In addition to this, we are involved in the evaluation of selections growing in field trials at the Federal Reseach Stations of Agroscope at Wädenswil and Pully. Results, conclusion, state of the art: - From different newer breeding sources in central Europe (Freiburg, Pully, Soyhère etc.), there is increasingly very interesting material available.

Neither are there appropriate breading programs on-going. Thus, knowledge is very scare. Stone fruit as cherries, plums and apricots are very difficult to produce organically. A key disease is Monilia sp. Further problems to overcome are susceptibility to leaf spot disease, aphids, insects, cracking etc. Additionally organic stone fruit, too, has to achieve the high and significantly changed market expectations (bigger and crisper fruit). The project aim is to find cherry (sweet and sour) and plum cultivars suited for organic production. Methodology: Precision trials are planted at Stone-Fruit Center Breitenhof of Agroscope Wädenswil at CH-Wintersingen. 15 cultivars of sweet cherry, 8 of sour cherry and 12 plum cultivars; 4 replicates. Some advanced cherry and plum cultivars are also under On-Farm observation. Apricots are evaluated only under On-Farm conditions in commercial organic orchards in canton Vallais. Results & conclusion: Only few of 15 sweet cherry cultivars (new selections and old traditional varieties) show a potential for organic production (Julka and FAW 1075).

Swiss soils are prevalently alkaline, and therefore it is necessary to modify the natural conditions. Traditionally this was done by adding peat. In order to preserve fragile environments, such as peat bogs, the use of peat in organic fiels production is forbidden. Project aims - Evaluate sawdust as a substrate for organic blueberry production in three different cultivation systems and with two different acidification products. Results - It is possible top use sawdust as a substrate for blueberry production in regions with alkaline soils; - The traditional system of digging a fosse and filling it with the substrate (cost intensive) can be replaced with a little fosse, done with a plough and filled with substrate (less cost intensive cost; - Acidification with citric acid does not have good results compared to sulphur applications. type: Project description type: NonPeerReviewed identifier: {Project} Blueberries: Torffreier Heidelbeeranbau.

However, quantitative and scientifically proved data are not available. However there is a high interest of the wine growers for appoved data on the efficiency of the bio-dynamic preparations. As in other countries bio-dynamic viticulture is rapidly growing in Switzerland. However, there is very little scientific evidence for the efficiency of the preparations. Thus, science-based recommendations for its use or optimisation cannot be given. Project aims including target group: To show the quantitative effects of bio-dynamic preparations on parameters of plant growth, disease tolerance, soil properties and finally also on vine quality. An additional goal of the project is the management improvement of the bio-dynamic growers participating in the trials. The results may show possibilities to optimize the standard and the specific bio-dynamic management measures of the growers. Methodology: In 2003 the project team that includes 4 bio-dynamic growers installed an On-Farm trial on 4 different sites of bio-dynamic vine farms. At each site 4 different treatment blocks are separated: a) with preparation 500 and with prep. 501; b) with 500 alone; c) with 501 alone; d) no preparations. Several times of the year plant growth and health is assessed. Vine quality is assessed by separated microvinifcation per treatment and site. The management of the 4 vineyards is harmonized. Results, conclusion, state of the art: First results do not show differences in disease incidence. There was a tendency found for more chlorophyll in leaves where prep. 501 is applied. At two sites there was a tendency for improvement of the quality of soil aggregates where 500 is applied. type: Project description type: NonPeerReviewed identifier: {Project} Bio-dynamic preparations in vine production: Wirkung biologisch-dynamischer Präparate in Rebbergen.

Das ist der Hauptgrund für eine komplett überarbeitete Neuausgabe der bisherigen Richtlinien (Heller et al. 1993; Commission romande de fumure, sous-commission arboricole 1993; Ryser et al. 1995). Der Wandel von Sorten, Veredlungsunterlagen, Anbauformen und Pflanzsystemen beeinflusst die Gesamtmenge an Nährstoffen, welche eine moderne Obstanlage braucht, die Aufteilung der Nährstoffe auf die verschiedenen Organe der Pflanze und auch die Nährstoffmenge, welche mit dem Ernteprodukt die Obstanlage verlässt. Damit stellt sich die Frage, wie moderne Anlagen bedarfsgerecht ernährt werden können. Die Anbausysteme sind dynamischer geworden, d.h. sie wandeln sich rascher als früher durch die dauernde Anpassung der Erwerbsanbaupraxis an aktuelle Marktbedürfnisse, technischen Fortschritt und Standortverhältnisse. Ziel moderner Obstproduzentinnen und -produzenten ist die Erzeugung eines Optimums an Fruchtqualität auf hohem Ertragsniveau unter Vermeidung der Alternanz. Die Baumernährung moderner Obstanlagen muss flexibel an die gegebenen Standortverhältnisse und Anbauziele angepasst sein. Die Gesellschaft verlangt zudem, dass mit den Ressourcen im Anbausystem schonend umgegangen wird. date: 2003 type: Report type: NonPeerReviewed format: application/pdf language: de identifier: /id/eprint/2880/1/bertschinger-2003-grundllagen-Obstkultur.pdf identifier: Bertschinger, Lukas; Gysi, Christian; Häseli, Andreas; Neuweiler, Reto; Pfammatter, Werner; Ryser, Jean-Pierre; Schmid, Andi and Weibel, Franco (2003) Grundlagen für die Düngung der Obstkulturen - Kernobst, Steinobst, Kiwi, Strauchbeeren.

The full cost account and the cash-flow time line are composed with the managerial-economical software-tool Arbokost. Due to higher (more than 100%) prices in the organic production, growing organic satisfies more return-oriented producers than growing certified integrated. However, the higher return in the organic production is bound to a higher risk. With the certified integrated production (IFP), return and risk are lower. ‘Arbokost’ is an economic farm management software tool for fruit growers. Per orchard it reflects a full cost account, the cash flows collected during 15 years, the earned income for each year and other different key data which are important for certified integrated and organic apple production in Switzerland. Also, the cost differences between Swiss organic and certified integrated apple production can be calculated. publisher: ISHS contributor: Prange, R.K. contributor: Bishop, S.D. date: 2010 type: Journal paper type: NonPeerReviewed format: application/pdf language: en identifier: /id/eprint/17811/1/bravin-etal-2010-acta-hort.pdf identifier: Bravin, Esther; Mencarelli Hofmann, Daniel; Kockerols, Katharina and Weibel, Franco (2010) Economics Evaluation of Apple Production Systems.

Vigorous and systematic steps were taken to limit the impact of the disease on fruit production and amenity plants. These efforts are codified in a Swiss law detailing prevention, eradication, control measures and issues of compensation. As with many Swiss legal directives, there is a defined coordination of federal and cantonal responsibilities and, in the case of fireblight, there is also an emphasis at all levels on personal responsibility of owners of susceptible objects (e.g. nurseries, orchards, host plants). Extension activities have been a key component in achieving compliance with disease management regulations and in obtained public support for control efforts.

This paper describes an environmental impact of an organic viticulture indicator (EIOVI) that can be reliably used in the management of organic vineyards. The EIOVI can be used as a decision support system for farmers and other property managers by evaluating the potential ecological impact of their choices, thus optimizing management options. The tool allows the simulation of vineyard management based on six agricultural and ecological modules. The EIOVI is a fuzzy expert system that calculates the relationship between the modules on the basis of a set of 64 decision rules. Initial testing (validation) has been performed using 20 simulations for six Swiss wine-growing estates. The results of these tests were promising; the EIOVI motivates managers to consider the wine-growing estate as a whole by subsummarizing all aspects of management. The visualization of results is very tangible and clearly shows that the use of this indicator could improve the management of the vineyard. With some improvements, the EIOVI will be a helpful assessment tool for vine growers, consultants, environmental agencies, and scientists. publisher: ASA, CSSA, SSSA date: 2009 type: Journal paper type: NonPeerReviewed format: application/pdf language: en identifier: /id/eprint/17947/1/fragoulis-etal-2009-j-environ-qual.pdf identifier: Fragoulis, Georgios; Trevisan, Marco; di Guardo, Andrea; Scorce, Andrea; van der Meer, Markus; Weibel, Franco and Capri, Ettore (2009) Development of a Management Tool to Indicate the Environmental Impact of Organic Viticulture.

In grapevines, these compounds belong to the stilbene family. Several studies have shown that resveratrol is usually triggered by infection of berries by Botrytis cinerea. In organic viticulture, grapevines are usually more stressed by attempted or successful infections of various pathogens than in conventionally grown grapevines. Furthermore, crop protection agents such as acidified clays or copper may trigger defence reactions of the plants. The aim of this study was to verify if differences between organically and conventionally produced wines exist.

Assessments were made of plant species present in the understorey at the time of collection. All leafroller larvae were reared to adults on artificial diet to identify leafroller species and parasitoids. Nearly half (47%) of all leafrollers collected in these orchards were located in the understorey, highlighting the importance of understorey and its management for the control of leafroller. Dock, clover and dandeliontype plants contributed 25% to the overall understorey, yet hosted 75% of the leafrollers collected from the understorey. Dolichogenidea sp. was the most abundant parasitoid (79%) attacking leafrollers found amongst the apple foliage, whereas Glyptapanteles demeter was dominant in the understorey (61%). Generally the number of leafrollers in an orchard was proportional to the abundance of broadleaf weeds and inversely proportional to parasitis. date: 2003 type: Conference paper, poster, etc. type: NonPeerReviewed format: application/pdf language: de identifier: /id/eprint/4863/1/Weibel-2005-leafroller.pdf identifier: Rogers, D.J.; Walker, J.T.S.; Moen, I.C.; Weibel, F.; Lo, P.L. and Cole, L.M.

Da es sich bei diesem Produkt um eine Kali-Seifenlösung handelt, besteht die Möglichkeit, dass es nach dessen Einsatz zu einer geschmacklichen Beeinträchtigung des Endproduktes Apfelsaft, bzw. Süssmost kommen könnte. Eine Untersuchung an der Hochschule Wädenswil mit Apfelsäften, denen Cocana zugesetzt wurde, kam zum Schluss, dass es einen Zusammenhang zwischen Kaliseife und Fremdgeschmack geben könnte. Um abzuklären, ob unter Praxisbedingungen eine geschmackliche Unterscheidung zwischen Saft aus mit Biofa Cocana RF behandelten Früchten und solchem ohne Einsatz des Mittels er-kannt werden kann, wurden Äpfel aus verschiedenen Einsatzvarianten des Produktes gesam-melt und jeweils separat gemostet. So konnten Proben aus der gleichen Produktion, einmal mit und einmal ohne Einsatz von Biofa Cocana RF, gewonnen werden.

Aepfel gemostet ohne vorheriges tauchen in Cocana-Lösung) wurde ein einstufiger Dreieckstest durchgeführt, um heraus zu finden, ob ein sensorischer Unterschied festgestellt werden kann. Der Dreieckstest gilt als sehr sensibler Test zur Prüfung ob zwei Muster sensorisch unterscheidbar sind. Resultate und Schlussfolgerungen Keines der sechs Probenpaare konnte von den 28 Prüfpersonen mit statistisch gesichertem Unterschied richtig erkannt, d.h. zutreffend unterschieden werden. Die Maximalzahl zutreffender Unterscheidungen war 14 von 28 Antworten, resp. 13 von 27. Um eine statistisch gesicherte Aussage zur Unterscheidbarkeit der jeweils zusammengehörenden Probenpaare zu machen, müssten bei 28 Prüfpersonen mindestens 15 die Proben richtig erkennen, bei 27 mindestens 14 (Irrtumswahrscheinlichkeit α = 0,05). Bei allen sechs Proben besteht also kein ausreichender Grund zur Annahme, dass ein senso-risch erkennbarer Unterschied besteht zwischen Apfelsaft aus Äpfeln, die mit Biofa Cocana RF behandelt wurden und Apfelsaft, der aus nicht behandelten Äpfeln hergestellt wurde. Bei den insgesamt 76 richtigen Antworten aus allen sechs Proben bevorzugten 39 Saft aus Äp-feln mit Behandlung, 36 bevorzugten den Saft, der aus Äpfeln ohne Behandlung hergestellt wurde, einer konnte sich nicht für eine Bevorzugung entscheiden. Es ist keine klare Tendenz der Bevorzugung für Säfte mit bzw. ohne Cocana ersichtlich. Innerhalb der richtigen Antworten bevorzugt die gleiche Prüfperson einmal Saft aus unbehandelten, einmal aus behandelten Äpfeln. Die fünf Apfelsaft-Proben, die aus der Ernte der Feldversuche hergestellt waren, stammen von Äpfeln die gemäss Pflanzenschutzempfehlungen mit Biofa Cocana RF behandelt wurden und zwar unter Berücksichtigung von Anwenderschutz, in richtiger Konzentration und korrekt ausgebracht, um einen optimalen Schutz zu erreichen. Die Saison 2003 war sehr trocken. Die Abwaschung von Pflanzenschutzmitteln bei Regenfällen war dadurch sicher geringer als in anderen Jahren. Das heisst, dass bei den hier geprüften Proben eher mehr Rückstände, die zu geschmacklichen Veränderungen führen könnten, auf den Früchten vorhanden sein können. Trotzdem konnte aber kein Unterschied zwischen Saft aus behandelten Fürchten und solchem aus unbehandelten Früchten festgestellt werden. Praxisgemässer Einsatz von Biofa Cocana RF führt demzufolge nicht zu einer geschmacklich erkennbaren Veränderung von Apfelsaft. date: 2004 type: Report type: NonPeerReviewed format: application/pdf language: de identifier: /id/eprint/2170/1/schaerer-et-al-2004-biofa.pdf identifier: Schärer, Hans-Jakob; Amsler, Thomas; Fuchs, Jacques and Weibel, Franco (2004) Sensorische Untersuchung von Apfelsaft aus Behandlungsversuchen mit Biofa Cocana RF.

Production in Alkaline Field Soils creator: Schmid, Andi creator: Suter, Francisco creator: Weibel, Franco creator: Daniel, Claudia subject: Soil biology subject: Fruit and berries description: Production of Vaccinium corymbosum L. is limited to acidic soils with high organic matter content. This specific soil requirement is limiting the possibilities to cultivate V. corymbosum L. in many regions of Central Europe. The aim of this study was to overcome the limiting production factors occurring under the soil and climate conditions of Switzerland: (1) evaluation of natural growing substrates without peat as required for organic production; (2) adjustment of the optimal pH in the growing substrate; (3) regulation of water issues (water quality and mulching) and (4) development of a suited planting system. Pine sawdust was evaluated to be the best alternative growing substrate compared to peat moss. Optimal pH adjustment in pine sawdust substrate was found to be 3.8 (CaCl2) and 4.2 (H22O). In field cultivation, an amount of 30 g S year-1 plant-1 to lower the pH of the pine sawdust ditches was sufficient for good plant and yield development. This acidification resulted in better growth (+48 %) and higher yield (+55 %) when alkaline ground water (357 mg L-1 CaC03) was used for irrigation. Acidification with citric acid gave poor results. A mulch of pine bark on the sawdust ridge increased growth by 59 % and yield by 25 %. The newly developed flat ditch system with low sawdust ditches buried partly into the ground was as suitable as the standard planting system with deep ditches lined with plastic film. By integration and application of these new findings, a system for commercial organic blueberry production under Swiss conditions and on alkaline soils was developed. publisher: Eugen Ulmer KG date: 2009 type: Journal paper type: NonPeerReviewed format: application/pdf language: en identifier: /id/eprint/17948/1/schmid-etal-2009-europ-j-hort-sci.pdf identifier: Schmid, Andi; Suter, Francisco; Weibel, Franco and Daniel, Claudia (2009) New Approaches to Organic Blueberry (Vaccinium corymbosum L.)

Erfolgt diese ohne Herbizide wird der Baumstreifen entweder mit organischen Materialien (Baumrinde, Holzhäcksel, Stroh) oder wasserdurchlässigem Kunststoffgewebe abgedeckt oder durch Hacken mit Spezialgeräten offen gehalten. Beide Methoden bergen jedoch gewichtige Nachteile in sich. Bei der Abdeckung sind dies die hohen Materialkosten, der z. T. hohe Kalieintrag (Erhöhung der Stippegefahr) und der erhöhte Mäusedruck. Das herkömmliche Hacken ist zeitintensiv, die Anschaffungs- und Wartungskosten geeigneter Hackgeräte sind hoch. Beim Sandwich-System bleibt ein schmales Band im Zentrum des Baumstreifens unbearbeitet. Links und rechts dieses Bandes werden - im Vergleich zur herkömmlichen Baumstreifenbearbeitung - zwei mindestens halb so breite Streifen durch Hacken offen gehalten. Gemäss neusten FiBL-Versuchsresultaten lässt sich beim Apfel zwischen der herkömmlichen Bewirtschaftung und dem Sandwich-System keine Differenz in der Ertragsleistung feststellen. Der Zuwachs des Stammumfangs lag im Sandwich-Verfahren sogar höher als bei der herkömmlichen Bewirtschaftung. Da beim Hacken Sandwich-Streifen keine Baumstämme im Weg sind, lässt sich die Arbeit rationeller verrichten. Zu diesem Zweck haben die Firma Santini und Braun gemeinsam mit dem FiBL SANDI entwickelt.

It has been hypothesised that organically grown fruits are healthier based on their higher content of phytochemicals. However, data on the bioavailability of phytochemicals from organically or conventionally produced plant foods are scarce. Methods Two human intervention studies were performed to compare the bioavailability of polyphenols in healthy men after ingestion of apples from different farming systems. The administered apples were grown organically and conventionally under defined conditions and characterised regarding their polyphenol content and antioxidant capacity. No significant differences in the polyphenol content and the antioxidant capacity from the organic and conventional farming system were observed. Results In the short-term intervention study, six men consumed either organically or conventionally produced apples in a randomized cross-over study. After intake of 1 kg apples, phloretin (C max 13 ± 5 nmol/l, t max 1.7 ± 1.2 h) and coumaric acid (C max 35 ± 12 nmol/l, t max 3.0 ± 0.8 h) plasma concentrations increased significantly (P < 0.0001) in both intervention groups, without differences between the two farming systems. In the long-term intervention study, 43 healthy volunteers consumed organically or conventionally produced apples (500 g/day; 4 weeks) or no apples in a double-blind, randomized intervention study. In this study, 24 h after the last dosing regime, the apple intake did not result in increasing polyphenol concentrations in plasma and urine compared to the control group suggesting no accumulation of apple polyphenols or degradation products in humans. Conclusion Our study suggests that the two farming systems (organic/conventional) do not result in differences in the bioavailability of apple polyphenols. publisher: Springer date: 2010 type: Journal paper type: NonPeerReviewed format: application/pdf language: en identifier: /id/eprint/17951/1/strake-etal-2010-eur-j-nutr.pdf identifier: Stracke, Berenike A.; Rüfer, Corinna E.; Bub, Achim; Seifert, Stephanie; Weibel, Franco; Kunz, Clemens and Watzl, Bernhard (2010) No effect of the farming system (organic/conventional) on the bioavailability of apple (Malus domestica Bork., cultivar Golden Delicious) polyphenols in healthy men: a comparative study.

Apples were harvested at five comparable commercial farms over the course of three years (2004−2006). In 2005 and 2006 the antioxidant capacity was 15% higher (p < 0.05) in organically produced apples than in conventionally produced fruits. In 2005 significantly higher polyphenol concentrations were found in the organically grown apples. In 2004 and 2006 no significant differences were observed (2004, 304 ± 68 μg/g organic vs 284 ± 69 μg/g conventional, p = 0.18; 2005, 302 ± 58 μg/g organic vs 253 ± 41 μg/g conventional, p = 0.002; 2006, 402 ± 100 μg/g organic vs 365 ± 58 μg/g conventional, p = 0.17). Year-to-year variations in the antioxidant capacity and the polyphenol content of up to 20% were more significant than the production method found within one year. Finally, flavanols and flavonols were major determinants of the antioxidant capacities in these apples. Overall, the production method had a smaller impact on the variation in the polyphenol content and antioxidant capacity of apples than the yearly climate. publisher: American Chemical Society date: 2009 type: Journal paper type: NonPeerReviewed format: application/pdf language: en identifier: /id/eprint/17949/1/stracke-etal-2009-agric-food-chem.pdf identifier: Stracke, Berenike A.; Rüfer, Corinna E.; Weibel, Franco; Bub, Achim and Watzl, Bernhard (2009) Three-Year Comparison of the Polyphenol Contents and Antioxidant Capacities in Organically and Conventionally Produced Apples (Malus domestica Bork.

Since 1989, we have cultivated resistant grape varieties such as Maréchal Foch, Léon Millot, Muscat Bleu, Cabernet Jura, Chancellor and Monarch (red), and Seyval Blanc, Bianca, Solaris, Phoenix and Excelsior (white). As a rule, we avoid applying even organic pesticides, and use solely biodynamic compounds (4 applications/year). The elimination of practically all plant-protection products has enabled us to establish a highly biodiverse organic agro-ecosystem with reduced impact on the environment. In addition, over a 20-year period, this system has resulted in the application of 270 kg less copper over our 4.5-ha surface area, as well as the saving of 18 t of fuel, which can be remarked as the “non-emission” of 47 t of carbon dioxide. In Switzerland, whose vineyards have a combined surface area of 15’000 ha, the potential annual savings in pesticides and fuel, to the benefit of nature, environment and climate, can be estimated at 225’000kg (225 t) pesticides and 1.5 Mio l (1500 t) fuel respectively, equating to the “non-emission” of 3.9 Mio kg (3900 t) of carbon dioxide. date: 2009 type: Conference paper, poster, etc. type: NonPeerReviewed format: application/pdf language: de identifier: /id/eprint/13902/1/Strasser_13902.pdf identifier: Strasser, Alfred and Coray, Maria (2009) Klimaschutz mit pilzresistenten Rebsorten - Fallstudie eines langjährigen Bioweinbaubetriebes.

However, the organic fruit industry has shown the lowest growth rates (1-5% market share) compared to other commodities. One major reason is the high production risk due to high disease and pest pressure in humid climates. Key pests and diseases in apple and pear include scab, sooty blotch, and fire blight as well as rosy apple aphid, pear sucker, and codling moth. In cherry, damages due to brown rot (Monilinia) and the cherry fruit fly make organic production almost unfeasible. In an ideal organic system, all possible measures that lead to improved stability of the system must be implemented. In fruit production, such measures include (i) use of resistant varieties (scab), (ii) active promotion of predators (rosy apple aphid), (iii) sanitation (cherry monilinia), (iv) microclimate management (planting density, covering trees), and (v) strengthening the plant self-defence system (e.g. building up of soil fertility, bio-dynamic preparations). At present, most organic orchards have been designed for conventional production and, therefore, lack most stabilising components. In consequence, organic fruit production still depends largely on direct pest and disease control methods. These include traditional pesticides such as copper, sulphur, and lime sulphur, pyrethrin, oil and soap preparations. More recently, new pest control compounds and techniques have been developed including neem products, granulosis virus, and mating disruption. New tools for disease control are less spectacular and focus on the replacement of copper (e.g. with clay powders and resistance inducers). The introduction of new equipment, materials, and Decision Support Systems (DSS) will further improve yield stability. However, other limiting factors such as weed competition, crop load regulation, and conventional market demands need innovative solutions. publisher: International Society for Horticultural Science.

Even within the tree rows different beneficial can be supported by selected plant species. In most experimental work done to stabilize the apple production system only single interaction effects were tested. However until now, no research group has quantified the additive effects of multiple measures on systembiodiversity and on the production economy. Our experiment combines all known measures of indirect pest and disease control measures in a near-to practical production model orchard without the use of any pesticide (not even organic ones). The orchard is split in 4 blocks: in two of them bio-control measures e.g. application of Granulosis Virus against codling moth (C. Pomonella) are applied; in the other two blocks no bio-control is applied. Standard commercial organic and integrated orchards with the disease-susceptible cultivar Gala in the vicinity of the model orchard are assessed by the same methods and serve as reference. Our intermediate results reveal that the self-regulating orchard developed already in the 2nd and 3rd leaf a clearly higher flora and fauna biodiversity compared to the reference orchards. The same happened in relation to the specific fruit beneficial e.g. the populations of aphid predators. In the self-regulating orchard they were capable to keep the aphid damages – in particular of the powdery apple aphid (D. plantaginea) - on trees and fruits under a commercially relevant level although the initial abundance of aphid colonies in spring was by far over the common threshold value. It is planned to continue the experiment until 2016. publisher: Fördergemeinschaft Oekologischer Obstbau e.V.

However, the organic fruit industry in European states still has a relatively low market share of less than 1-5% compared with organic vegetables, milk and eggs that have achieved market shares of close to 10% of the total market. As well, conventional fruit growers still hesitate to respond to the generally good organic market demand. A major reason for this behaviour is the continuing high production risk due to less availability of effective management tools for the control of pests, diseases, weed and biennial bearing. The key pests and diseases in apple and pear include scab, sooty blotch, and fire blight as well as rosy apple aphid, pear sucker and codling moth, as well as post-harvest diseases like Gloeosporium rot. Another reason that holds up organic fruit expansion is that in fruit production, in contrast to milk or wheat, new and organic-specific marketing attempts are necessary for organic cultivars, less cosmetic “beauty”, etc.) but are presently scarce. In an ideal organic production system, all possible measures that lead to improved stability and self-regulation of the agro-ecological system have to be implemented (e.g. resistant cultivars, bio-diversity areas, lower planting densities, measures to avoid inoculum build-up, soil fertility). At present, most organic orchards have almost the same design as found in conventional production and often do not include system stabilising elements. Therefore, organic fruit production still depends largely on direct pest and disease control methods. In the last decade effective compounds and techniques have been developed such as Neem preparations, granulosis viruses, and mating disruption to control pests. Some new plant protection techniques e.g. clay powders, resistance inducers, better spray technique and spray timing models have been introduced. The introduction of new equipment, compounds, cultivars and decision support systems will further improve yield stability. However, for other limiting factors, such as weed competition, crop load regulation and market demands in respect to quality, innovative solutions have to be developed. The challenge for the future is to build up a credible (“true-organic”) and high quality multi-factor oriented organic fruit production that combines single factor solutions to a self-regulating, and possibly even organic pesticide-free, production system. Progress in this direction will lead to innovative organic production and marketing concepts that are clearly different from conventional ones. To achieve these goals, creative efforts along the whole chain involving producers, consumers, retailers, advisory services and researchers are essential. publisher: International Society for Horticultural Science contributor: Lynch, D.L. contributor: Prange, R.P. date: 2007 type: Journal paper type: NonPeerReviewed format: application/pdf language: de identifier: /id/eprint/11055/1/weibel-etal-2007-Acta737_OrgApplPear.pdf identifier: Weibel, F.P.; Tamm, L.; Wyss, E.; Daniel, C.; Häseli, A. and Suter, F.

Das Potenzial der resistenten Sorten, um mit nicht-resistenten sensorisch und auch vom Äussern her mitzuhalten, ist absolut gegeben. 2. Die einzelnen Kandidaten haben ihre bekannten Stärken und Schwachpunkte (z.B. Ariwa oder Topaz). Dem ist in der Produktion mit sorgfältigem Einhalten der wichtigsten Massnahmen zu begegnen: a) Genügende Ausdünnung schon ab Blüte bis vor der Ernte, b) korrekter Erntezeitpunkt (Streifindex 029-0.12 bei Ariwa und 0.17-0.10 bei Topaz); c) tadellose Lagerung und frühzeitiger Verkauf. 3. Ecolette konnte mit sehr guten Resultaten im Aussehen und im Geschmack frühere Ergebnisse bestätigen; sie ist damit aus heutiger Sicht zu Recht in den Sortenteam-Anbau aufgenommen worden, wo sie der Sortimentsbereicherung in der säurebetonten Geschmacksgruppe dienen soll (siehe dort im Tagungsband). 4. Im Äussern eher im Mittelfeld, hingegen geschmacklich Top fiel die neue FAW-Selektion 8244 auf. Sie ist in den Exakt- und Ringversuchen integriert und könnte bei dort guten Erfahrungen (insbesondere auch mit der Lagerung) eine Kandidatin für einen baldigen Sortenteam-Anbau werden für den Bereich der würzig-säuerlichen Sorten. 5. GoldRush aus dem Wallis hat sehr gut abgeschnitten und bestätigt damit, dass die stattgefundenen Pflanzungen dort ihre Berechtigung haben. Die in Güttingen (Thurgau) angebauten und ebenfalls sehr spät reifenden und nach Züchterangaben lang lagerbaren DL-Selektionen wurden hier ganz klar als zu wenig ausgereift beurteilt. Auch sie sind deshalb, wenn überhaupt, ein Fall für den Anbau im Wallis.

Das Sortenteam wählt aus bereits vorgeprüften Sorten solche aus, die bestehende Sortimentslücken schliessen oder bisherige Sorten verbessern könnten. Diese "Team-Sorte" wird auf 2-4 Bio-Betrieben im Vertragsanbau produziert. Die Gesamtfläche ist so gross, dass mit den Erträgen des dritten und vierten Standjahres Testverkäufe durchgeführt werden können. Für die Früchte der Testverkäufe erhalten die Produzenten eine vertraglich festgelegte «Pionierprämie». Aufgrund der agronomischen Erfahrungen der Pionierbetriebe und den Kundenreaktionen entscheidet anschliessend das Sortenteam gemeinsam, ob die Sorte weitergeführt werden soll oder nicht; und falls ja, mit welchem Mengenziel. Im Falle eines Neins wären für die Produzenten dank den «Pionierprämien» für die Früchte die Investitionskosten ungefähr gedeckt. Das Konzept Sortenteam verbessert somit auch den Zustand, dass zu viele Produzenten unkoordiniert und mit zu hohem finanziellen Risiko auf eigene Faust mit Sorten experimentieren müssen. publisher: Forschungsinstitut für biologischen Landbau, Frick, Schweiz contributor: Häseli, Andreas date: 2004 type: Book chapter type: NonPeerReviewed format: application/pdf language: de identifier: /id/eprint/2777/1/weibel-2004-sorten-und-unterlagen-bioobstbau.pdf identifier: Weibel, Franco; Häseli, Andreas; Schmid, Andi and Leder, Alfred (2004) Sorten und -Unterlagen für Bioobstbau: Kurznachrichten 2003/2004.

The FGC is providing to the buyers additional information on the specific flavour direction of that "unknown" apple cultivar in front of them (mild to sweet; spicy-tart; predominantly tart). In 2002 a consumer behaviour study was undertaken by «IHA/GfK-Switzerland» Institute to evaluate the consumer response to the FGC. The results reveal that 36 % of the persons interviewed at the point of sale considered additional information on the flavour direction of the apple cultivars as «important» and 40 % as «very important». Information on flavour direction was considered as the second important information at the shelf (59 % score), compared to the general presentation of the apples with 78 % score. On basis of these positive results, Coop introduced the FGC also for conventional apples. One year later, also the biggest supermarket retailer of Switzerland «Migros»introduced a FGC for organic and conventional apples. To develop further the FGC, in the year 2002, a consortium of the supermarket chain Coop Switzerland, organic apple growers, retailers and FiBL experts joined together in a so called «Variety Team». There, in contrast to Variety Clubs, the focus is not a particular variety but the active creation and promotion of an attractive assortment of scab resistant apple varieties in a well co-ordinated and thus for growers and retailers most efficient way. Investments and risks are evenly shared between the Team Partners. The first cultivar promoted is «Ecolette». publisher: Fördergemeinschaft Ökologischer Obstbau.e.V.

Most of the production occurs on freshly converted orchards with cultivars very sensitive to apple scab (Venturia inaequalis) that in humid conditions need an intensive plant protection program. For the future development of organic fruit growing towards a credibly sustainable production it is necessary to replace these cultivars with scab resistant or tolerant cultivars. Cultivar testing under organic growing conditions is therefore an important task. We describe our testing concept that consists of precision trials where cultivars are tested with an without aphid control and with and without crop load regulation. In parallel, we carry out on-farm trials with the most promising cultivars on up to 10 commercial, certified organic farms in all apple growing regions of Switzerland. Our experience with the concept is mostly positive because recommendations for the organic growers can be made relatively fast and reliably. However the test system is costly and labor intensive. publisher: International Society for Horticultural Sience (ISHS) contributor: Janick, J. date: 2003 type: Book chapter type: NonPeerReviewed format: application/pdf language: de identifier: /id/eprint/2801/1/weibel-et-al-2003-acta-horticulturae-artikel.pdf identifier: Weibel, Franco; Schmid, Andi and Häseli, Andreas (2003) Efficient Multi-location Testing of Scab Resistant Cultivars for Organic Apple Production in Switzerland.

Es handelte sich um die 3. Lese (12. Okt. 2003), da diese erfahrungsgemäss am meisten Gloeosporium gefährdet ist. Wir haben alle Behandlungen in einer 200 l Wanne (gefüllt mit 70 l Wasser) durchgeführt. In der Behandlung mit heissem Wasser wurde die Wassertemperatur durch Nachfüllen stabil zwischen 51.5 und 52.3°C gehalten. In den Behandlungen mit den Produkten "Jet 5" und Wasserstoffperoxyd haben wir die Produktkonzentrationen nach der Behandlung jeder Repetition durch Analysestäbchen von Merckoquant kontrolliert und je nach Bedarf mit dem jeweiligen Produkt nachgefüllt. Es wurden Fruchtkistchen von je 25 Früchten in 6 Wiederholungen pro Verfahren getaucht. Anschliessend wurden die Proben zur Vermeidung von Kontamination über die Luft im Lagerraum in Frischhaltebeutel verpackt. Die Lagerung erfolgte in zufälliger Anordnung der Obstkisten bei 2 ° C und 92 % rLF. publisher: Forschungsinstitut für biologischen Landbau, Frick contributor: Häseli, Andreas date: 2004 type: Book chapter type: NonPeerReviewed format: application/pdf language: de identifier: /id/eprint/2772/1/weibel-2004-bekaemfung-von-gloeosporium.pdf identifier: Weibel, Franco; Suter, Francisco and Zingg, Daniel (2004) Bekämpfung von Gloeosporium auf Apfel mit Nacherntebehandlungen.

Dies erlaubt dem Praktiker zur Erhöhung und Optimierung der Ausdünnwirkung zwei evt. sogar drei Durchgänge mit dem Fadengerät vorzunehmen (gezielt auf gewisse Blütenstadien wie z.B. die Königsblüten oder die späten Blüten am 1-j. Holz). Limitierend ist, dass es nicht so einfach ist, mit derart hohen Geschwindigkeiten durch die Anlage zu preschen. H. Gessler hat in der Zwischenzeit ein doppelspindliges Fadengerät gebaut, dass bei Normalgeschwindigkeit den selben Effekt erzielt wie das schnellere Fahren. Die Erfahrungen mit Vinasse-Produkten sind sehr interessant, bedürfen aber noch einer sehr genauen Überprüfung zumal soeben 2 neue Vinasse Produkte in die BIO-SUISSE Hilfsliste aufgenommen worden sind.

This strong growth of organics is underpinned by consumer concern over genetic engineering, food safety, health and nutrition (is it safe and healthy to eat?) and greater awareness of environmental issues (Torjusen, and Sangstad, 2004; Granatstein and Kirby, 2006). For farmers this provides an important opportunity in the ‘search for’ and ‘development of’ niche, new and nontraditional premium earning markets. However on-going improvements in conventional food production systems in terms of visible produce quality, but also with respect to environmental criteria, require a clear demonstration of the additional values that organic food can provide for the consumers and for the sustainability of food production and the environment (see Chapter 2). Sound scientific studies quantifying ‘added values’ play a key role in the marketing of organic produce if appropriately communicated to consumers, but are also important in gaining continued political support for an expansion of organic agriculture. Organic fruit production is one of the most important and challenging areas of organic production for a variety of reasons. publisher: Woodhead Publishing Limited, Cambridge, England contributor: Cooper, J. contributor: Niggli, U. contributor: Leifert, C. date: 2007 type: Book chapter type: NonPeerReviewed format: application/pdf language: de identifier: /id/eprint/13340/1/weibel-2007-OrganicFoodBook_Leiffert_Chapt16.pdf identifier: Weibel, Franco P. and Alföldi, Thomas (2007) Improving the quality and shelf life of fruit from organic production systems.

The 17 trials reported were carried out during flowering period in the years 2003, 2004 and 2005 on the cultivars ‘Pinova’, ‘Gala’, ‘Maigold’, ‘Elstar’, ‘Breaburn’, ‘Golden Delicious’ and ‘Otava’ at different sites. The results confirm the good efficiency of mechanical thinning with the rope thinner and the thinning potential of vinasse, a by product of molasses. Different vinasse products were tested (K-Vinasse, light-vinasse, N Vinasse; NK-Vinasse) and it was observed that those containing less nitrogen had a minor thinning effect. To avoid phytotoxicity on leaves, the concentration of N-Vinasse should not exceed 10%. It seems that for ‘Gala’ higher concentrations are needed, 7.5-10%, whereas with ‘Maigold’ the efficacy of N-Vinasse was the same with the 2.5% concentration as with 5% and 10%. On the other hand, partly good results were obtained when N-Vinasse was over-concentrated to 12 or 15%, applied at warm weather and rinsed with clear water 4-6 hours later to avoid the phytotoxic effect (“burn & rinse” method). Corn Oil (5%), a commercial product from New Zealand, gave encouraging results. Lime sulphur (2%) did not effectuate a significantly better thinning effect. The best method tested with a fruit set reduction by 62% and 3,05 times higher flower bud set next year was achieved with a combination of rope thinner and N-Vinasse: rope thinner to thin the peripheral branches and to exert a physiological stress; and N-Vinasse to thin the inner parts of the canopy that the ropes can’t reach. Other tested products did not show satisfying effects. Trials also confirmed the importance of applying these thinning agents at least two times, at the appropriate phenological stage of flowering period mainly at F2 (full bloom) and G (= F2 of the one-year old shoots) and in case at F (king flower open). Hitting also the flowers of the one-year old shoots is important to break bi-annual bearing. Pollen tube growth was assessed by fluorescence microscopy. Almost complete inhibition of pollen tube germination was observed with Lime Sulphur and over concentrated N-Vinasse (12%%) whereas with N-Vinasse at 5%% inhibition was 50%% less compared to untreated styles.. Overlooking all trials, combining N-Vinasse and rope thinner was the most efficient strategy for flower thinning. However, after our trials, its efficacy seems to depend strongly on climatic conditions and phenological stages: treatments with N-Vinasse should be carried out at warm and sunny days above 16, better 18-20 deg. C. to maximize desiccation on the styles; whereas the rope thinner should be applied during periods of cold and clouded weather to maximize the thinning effect due to physiological stress and shortage of assimilates to the fruitlets. date: 2008 type: Journal paper type: NonPeerReviewed format: source language: de identifier: /id/eprint/13369/1/Weibel_Thinning_EuJourHort_6.doc identifier: Weibel, Franco P.; Chevillat, Véronique S.; Rois, Elena; Tschabold, Jean-Luc and Stadler, Walter (2008) Fruit Thinning in Organic Apple Growing with optimized Strategies including natural Spray Products and Rope-Devices.

Il est connue que la thermothérapie (plonger les pommes pendant 2-3 min. dans l’eau chaude de 50-52 deg.) peut supprimer bien le développement du pathogène relativement bien. Les désavantages de la thermothérapie sont sa consommation d’énergie significative, ses hautes coûts d’investissement et finalement que les dégât latentes de G. album prove-nant du champ deviennent visible peu de jours après le traitement ce qui pouvait dévaloriser jusqu’à 30 % de la récolte. Le but de nos études c’est de trouver des méthodes de lutte contre Gloeosporium album et perennans comme alternative à la thermothérapie. Dans nos essays sur plusieurs années avec les variétés Pinova et Topas ni les produits oxi-dants (Jet5, H2O2, Nitrit, thé vert, thé de prèle ) ni l’ozone mis à l’eau (froid, 17 deg.) ont ap-porté des résultats régulièrement satisfaisants (pas de différence comparé avec les pommes non traitées). Les pertes ont atteint 60-80% après conservation et justqu’à 90 % après 10 jours de shelf-life de plus. A partir de 2004 nous avons aussi testé des eaux électrolytiques (Anostel® et Cathostel®), une technique de désinfection qui vient surtout du secteur médicinal. Elle est propre, sans formation des résidus dans les produit ou dans l’environnement. En plongeant les pommes sériellement dans ces solutions pendant 5 min. chaque, l’efficacité n’était pas aussi bonne qu’avec thermothérapie (75 % vendable après conservations) mais beaucoup meilleur (62 % vendable) qu’avec tout les autres oxidants (48 % vendable). C’est pourquoi nous essayons d’optimiser la méthode des eaux électrolytiques avec des essaies en cours de cette année. Car l’attaque des Gloeosporium sur champ peut avoir un effet tellement nocif malgré des traitements post récolte, nous avons aussi testé des stratégie de contrôle pre-récolte à partir du mois de Juillet avec des produits antagoniste (la levure Aureobasidium pullulans), KBV-Lactopéroxidase, Calcium-polysulphurique, cuivre, Calcium-Chloride (pour fortifier la cuti-cule) et Mycosin (argile acidifié). De tout les produits testés pre-récolte seulement le Mycosin donnait des résultat satisfaisant, comparable à la thermothérapie. Aussi nous avons pu prouvé qu’avec Pinova le savon de coco pour lutter contre la maladie de suie (Cocana) à un effet significativement aggravant l’incidence de Gloeosporium. Le but de nos études actuels c’est de développer des stratégies combiné pre- et post récolte (sans thermothérapie) qui n’interfèrent pas avec la lutte contre les autre maladies (suie, ta-velure, oidium) et qui se complémentent d’une façon idéale et écologique. date: 2005 type: Journal paper type: NonPeerReviewed format: application/pdf language: de identifier: /id/eprint/7042/1/weibel-2005-Gloeosporium-GRAB.pdf identifier: Weibel, Franco P.; Hahn, Priska; Lieber, Susanne; Häseli, Andi; Amsler, Thomas and Zingg, Daniel (2005) Lutte contre Gloeosporium (album et perennans) des pommes biologiques Post-Recolte avec des produits oxidants et des eaux électrolytiques,et Pre-Recolte avec differents produits biologiques entre 2001-2004.

Southern states, especially Italy, Spain and France have the largest land area with organic fruit, are also growing olives, citrus and chestnuts. Mainly increasing interest of supermarket chains is responsible for this buoyancy, but also the availability of better plant protection products e.g. granulosis virus and mating disruption against codling moth, and Neem oil against Rosy Apple Aphid. State subsidies varying from 600 to more than 1600 Euro /ha/y in the EU-countries (15) are less decisive for the conversion of top fruit production. Market share of organic table fruit is only 1 to 2 %, reaching 4 to 5 % in Switzerland. For Switzerland, we estimate a market potential of around 12 to 15 %, which is already achieved with organic vegetables. In order to reach that percentage, better solutions for several key problems have to be found, e.g. control of scab, fire blight, sooty blotch, brown rot, weed management, fertilisation and crop load regulation. Also the assortment of organically produced “modern-standard” varieties is not satisfactory, in particular with stone fruit. The economics of organic fruit growing is comparatively healthy, however, it depends on receiving a one third higher farm gate price for the product. In Switzerland the benefit of organic orchards is 16 % higher compared to integrated fruit production; but labour hours exceed those of IFP by 7%, due to blossom thinning by hand, manual weed control and mice control. Supermarkets have a tendency to just “substitute” conventional with organic fruit if requiring organic fruit from disease susceptible varieties with no cosmetic blemishes. This can/does feed back to the growers resulting in “substitutional” production with disease and pest sensitive orchards managed with intensive “organic” spray and fertilisation programs. This certainly does not correspond with either the original concept of organic farming or with expectations of organic consumers. Thus, still a lot of development - also on the marketing side - has to be undertaken. publisher: International Society for Horticultural Science ISHS contributor: Bertischinger, L. contributor: Anderson, J.D. date: 2004 type: Book chapter type: NonPeerReviewed format: application/pdf language: en identifier: /id/eprint/2993/1/weibel-et-al-2004-fruit-growing-europe.pdf identifier: Weibel, Franco P.; Häseli, Andreas; Schmid, Otto and Willer, Helga (2004) Present Status of Organic Fruit Growing in Europe.

The orchards were similar in microclimate, soil conditions and planting system. To assess inner fruit quality we investigated at the beginning and at the end of cold storage: (i) standard parameters (firmness, sugar, malic acid., mineral content); (ii) sensorial quality by panel tests; (iii) health related components (23 phenolic compounds, nutritional fibres; vitamins); and (v) fruit «vitality quality» by holistic approaches (crystallisation in copper chloride, self degradation tests, feeding preference tests with laboratory rats). The most significant differences were found in year one of the study, and were by tendency confirmed in the following two years. In year one all fruit samples of organic orchards had significantly firmer fruit flesh (14%), a 10 % higher index of inner quality (on basis of sugar and malic acid content and fruit flesh firmness), and 15% higher taste scores than conventional ones. Phosphorus content of the fruit flesh was 31% higher in organic apples and closely correlated (r2 = 0.93) with the index of inner quality and sensory score (r2 = 0.69). No extraction method of Phosphorus in the soil (water, NH4-EDTA, citric acid, CAL) correlated with the P-content in the fruits. However, P in the fruit flesh correlated by r2 = 0.72 with the microbial activity of the soil expressed as the ratio of microbialbound Nitrogen and Carbon in the soil. With a value of 3.85 the Cmic:Nmic ratio was 44.5 % lower (thus more favourable) in organic tree strips. Flavanols, with 65.7 % of the total polyphenol content were the dominant group of polyphenols. The content of flavonols was 22.7 % higher in organic apples in the first year and 15.6 % in the average of the three years. The self-degradation test didn't provide significant differences. Laboratory rats, showed a tendency to prefer IP apples probably due to their advanced ripeness. Thus rat behaviour did not correspond with the sensory panel judgement. The picture forming method provided a correct reproducibility with repeated blind samples before and after storage (r2 = 0.83), and distinguished 100 % correctly organic an IP fruit in the first year. In the second year there was one miss qualification. The average value over three dates of the index for «vitality quality», which was especially created for this study, was 44.6 % higher with organic apples The picture forming methods correlated well with sensory scores and standard quality (r2 = 0.63) in the first year. The study revealed interesting and consumer-relevant differences between organic and integrated apples with standard and holistic methods. date: 2004 type: Conference paper, poster, etc. type: NonPeerReviewed format: application/pdf language: de identifier: /id/eprint/9100/1/Weibel-etal-2004-Qual_Weinsberg_04.pdf identifier: Weibel, Franco P.; Treutter, Dieter; Graf, Ursula and Häseli, Andi (2004) Geschmack- und gesundheitsrelevante Qualität von ökologisch angbauten Äpfeln: Eine 3jährige Feldvergleichsstudie mit standard- und ganzheitlichen Untersuchungsmethoden.

[Unpublished] relation: https://orgprints.org/id/eprint/2586/ title: Organic Viticulture in Europe creator: Willer, Helga creator: Häseli, Andreas creator: Levite, Dominique creator: Tamm, Lucius subject: Viticulture description: Introduction Organic agriculture is a thriving sector in Europe, and in some countries 10 % of the agricultural area is organic. Not so, however, for organic viticulture: the percentage of organic viticulture land compared to all vineyards is lower than for organic agriculture. This is due to several constraints in the sector of production techniques, in marketing, legislation and state support. Material and Methods So far no official data on the current status of organic viticulture in Europe exist. Even though most countries in the Europe collate data on their land under organic management, information on land use patterns is not always available. For this paper several information sources were used including various conference proceedings on the subject and the results of a survey among experts. Results and Discussion According to a FiBL-survey in Europe almost 60 000 hectares of vineyards are managed organically (end 2000); corresponding to ca. 1.6 percent of all vineyards. The main producing countries are Italy, followed by Spain and France. Highest percentages of organic vineyards compared to conventional vine land are reached in Italy and Portugal (both 3.4 %). Growth of the organic vineyards is, however, not as fast as that of organic land in general. This is due to several factors: • With the organic cultivation techniques an optimum balance between pest and predators is enhanced and diseases are reduced. Some major problems have, however, remained for the organic wine growers. In all European countries fungus diseases like powdery and downy mildew (Uncinula necator and Plasmopara viticola) and grey mould (Botrytis cinera) pose particular problems to organic wine growers. Research is urgently needed in order to find efficient copper substitutes. • According to many experts the only long-term solutions to the fungus problems are interspecific hybrids. Several wine (blind) tastings with traditional and fungus tolerant varieties have shown that the sensorial quality of the new varieties can even be higher than that of the traditional varieties. • The Southern European countries produce organic wine mainly for export. In France for instance, 70 % of the organic wine is exported. Germany is the biggest market for organic wines in Europe, and here 70 % of the wines consumed are imported. Even though the market for organic wine is growing, especially in Northern Europe, the information about the quality of organic wines still needs to be improved. In many countries, organic wine producers have successfully taken part in “conventional” wine tastings. • In almost all European countries, organic viticulture is subsidised under the various agri-environment programmes. The payments differ however substantially between the countries; the amounts paid per hectare and year ranging between 500 and 900 Euro. These sums cannot cover the extra costs involved in the organic farming system. Also, the differentiation between the subsidies for integrated and organic farming is far too small, and therefore the incentives for wine growers to convert their land is not sufficient. Conclusions Organic viticulture has clearly trigged many innovations in conventional viticulture. Many techniques which were developed by organic viticulture are applied by conventional wine growers. Several challenges, however, need to be tackled in order to increase the organic vine area and attain growth rates similar to those of organic agriculture in general: 1. There are still no satisfactory solutions to various diseases and pests. Fungus diseases are a pan-European problem, and efficient copper replacements still need to be found, and research efforts need to be increased substantially. A solution to the fungus problems are the interspecific hybrids, for which further breeding efforts are urgently needed. 2. State and EU-regulations hindering wine growers to plant these varieties and market the wine derived from their grapes need urgently to be changed. 3. Organic viticulture is not subsidised adequately in any European country. Organic wine growers need higher subsidies in order to compensate lower yields and the higher labour input. The differentiation between integrated farming should be greater in order to provide sufficient organic conversion incentives . 4. The labelling of organic wine is still not satisfactory. It should be possible in all European countries to declare on the label that a wine stems from organic viticulture in order to strengthen consumer confidence. 5. Information on the quality of organic wines should be improved. publisher: Canadian Organic Growers, Victoria, Canada contributor: Canadian Organic Growers, x date: 2002 type: Conference paper, poster, etc. type: NonPeerReviewed format: source language: de identifier: /id/eprint/2586/1/willer-et-al-2002-viticulture-abstract.doc format: source language: de identifier: /id/eprint/2586/2/willer-et-al-2002-viticulture-long-version.doc format: application/pdf language: de identifier: /id/eprint/2586/3/willer-et-al-2002-viticulture-presentation.pdf identifier: Willer, Helga; Häseli, Andreas; Levite, Dominique and Tamm, Lucius (2002) Organic Viticulture in Europe.

This research was initiated to investigate the effects of alternative orchard floor management systems compatible with organic production on soil parameters using the“Pacific Gala” apple cultivar (Malus × domestica Borkh.) on three rootstocks of varying vigor. Alfalfa hay mulch, propane flame burner, and Swiss sandwich system(combination of resident vegetation and tilled strips)were compared from 2001 to 2005. These treatments were applied to tree rows which provided different vegetation-free areas. Contrasting additions of organic matter were evaluated for their effect on soil organic matter (SOM), C content, nitrate and ammonium availability, moisture, and soil food web through nematode populations. Laboratory incubations to determine C and N mineralization potentials were performed. During this time period, SOM increased under the mulched soil and slightly less under the Swiss sandwich system (SSS) but in this last case without external inputs. Carbon and N pools were not impacted by flame burning (FL) but were enhanced by alfalfa hay mulch (MU) and to a lesser extent by SSS. Nitrate-N content in soil under MU increased between five and ten times compared to SSS and FL. Total number of nematodes was higher for SSS and MU compared with FL treatment; however, SSS had the most structured soil food web, an important sustainability trait, while MU had the least date: 2011 type: Journal paper type: NonPeerReviewed format: application/pdf language: en identifier: /id/eprint/20305/1/Soil_properties_under_different_orchard_floor_management_systems_for_organic_apple_production-Zoppolo_et_al-2011.pdf identifier: Zoppolo, Roberto J.; Stefanelli, Dario; Bird, George W.; Perry, Ronald L. and Weibel, Franco (2011) Soil properties under different orchard floor management systems for organic apple production.
