Summary
Syftet med projektet är att öka lönsamheten i ekologisk grönsaksodling, framför allt inom kålodling, genom att utveckla ett odlingssystem för samodling av kålsorter eller variteter. Den teoretiska idén bakom odlingssystemet är att minska förluster på grund av skadeinsekter genom att manipulera insekternas äggläggningsbeteende och genom att minska överlevnaden hos larver. Det huvudsakliga fokuset i projekt kommer att vara att minska effekten av kålflugor men i ett längre perspektiv är syftet också att utveckla en kvantitativ metod som kan användas vid utveckling av motsvarande odlingssystem för andra grönsakssorter.
Summary translation
The aim of this project is to increase the profitability of organic vegetable production by increasing the genetic diversity within fields. The type of cropping systems that we will develop will mix either Brassica crops or crop varieties, and we will in the process use a model approach for optimizing the system. The theoretical idea behind the increase in genetic diversity is to reduce losses to pest insects by manipulating the egg-laying behaviour by females and by reducing the survival of attacking larvae. This will be done by first establishing the level of resistance and tolerance of different crops and crop varieties and then mixed these in such a way that sensitive crops will receive lower loads of pest insects. These mixtures will then be evaluated in a set of field experiments. In these experiments we will also examine the spatial scale at which a maximum effect is achieved by manipulating the spatial configuration within a given crop mixture, and eventual interactions with natural enemies.
