Summary
Prosjektet Organic-PLUS har som målsetting å finne alternativer til uønskede innsatsfaktorer i økologisk landbruk. En av disse innsatsfaktorene er kopper, som brukes lovlig over hele Europa. Mest brukt blir det brukt i middelhavslandene, der det dyrkes blant annet tomater, oliven og sitrusfrukter. Det har gjort at kopper har blitt akkumulert i jordsmonnet der dette virkemidlet brukes. Det er uheldig, da tungmetaller som kopper har negativ innvirkning på planter og dyr samt humanhelsen.
I Spania forskes det på hvordan man kan erstatte bruk av kopper med andre produkter ved økologisk produksjon av tomater i veksthus. Der har de vist at kaliumbikarbonat kan erstatte kopper. I tillegg har de vist at valg av tomatsort også er av største betydning.
I Hellas har de vist at behandling av olivenplanter med biosimulanter som styrker plantene og svovelkalk kan erstatte bruk av kopperprodukter. Det har i tillegg en positiv eller ingen negativ effekt på fruktstørrelse og salgbar avling.
I Italia forskes det på biologisk kontroll av soppsykdommer i økologisk sitrusdyrking. Der har de vist at det finnes flere alternative stoffer som virker positivt både i vekstkammer og i feltforsøk. Disse stoffene kan virke til og med bedre enn kopperprodukter som brukes i dag.
Summary translation
The Organic-PLUS project aims to find alternatives to undesirable input factors in organic farming. One of these factors is copper, which is used legally throughout Europe. It is most common used in the Mediterranean countries where tomatoes, olives and citrus fruits are grown, among other things. As a result, copper has accumulated in the soil where this measure is used. This is unfortunate since heavy metals as copper have a negative impact on plants and animals as well as human health.
In Spain, research is carried out on how to replace the use of copper with other products in organic production of tomatoes in greenhouses. There they have shown that potassium bicarbonate can replace copper products. In addition, they have shown that the choice of tomato variety is also of most importance to reduce fungal damages.
In Greece, they have shown that treatment of olive plants with bio stimulants that strengthen the plants and lime sulfur can replace the use of copper products. It has a positive or no negative effect on fruit size and saleable yield.
In Italy, research is being carried out on how to use biological control agents on fungal diseases in organic citrus cultivation. They have shown that there are several alternative substances that have a positive effect by reducing disease development both in growth chamber and in field trials. These substances may even work better than the copper products used today.
