Development of strategies to maintain and improve the stability of yield, the use of functional biodiversity and to reduce the use of plant protection products in organic apple production (Erarbeitung von Strategien zu Erhalt und Verbesserung der Ertragsstabilität im Ökologischen Tafelapfelanbau)

Project


Project code: 2822OE154
Contract period: 15.01.2023 - 31.01.2028
Budget: 381,360 Euro
Purpose of research: Applied research
Keywords: agricultural biodiversity, biological diversity, biological plant protection, insects, pome, climate protection, fruit production, crop production

The project aims to adress the existing weak points of the production system of organic apple growing and to develop combination strategies that improve the stability of yields, reduce the use of plant protection products and enhance the insect biodiversity in the orchards. It is intended to reduce the applications with codling moth granulovirus (CpGV) in late summer and to test new isolates and virus types. In strong collaboration with the codling moth strategy a sustainable strategy to reduce fungicide application with main focus on copper applications in late summer shall be developed. As part of a combination strategy to control the woolly apple aphid, vegetation management measures to enhance early occurring ladybirds and hoverflies shall be elaborated. The potential of vegetation management to reduce fruit damage by pentatomids in Saxony will be investigated.
