BONDGENOOT: Biodiversity and aphids: ecosystem management in apple orchards

Organic apple growers are coming under increasing pressure due to restrictions on the use of plant protection products. At the same time, they wish to be less dependent on external inputs. This is driving the need for more robust orchard systems. Growers have also observed that pest pressure varies significantly between farms, raising questions about the role of orchard management, biodiversity and system choices.
The BONDGENOOT project is investigating which factors make orchard systems more robust and how an ecological systems approach can strengthen natural pest control. First, a systems-oriented analysis of the participating farms is being carried out through interviews and field visits. In addition, field monitoring is being carried out and practical measures are being tested that can enhance functional agrobiodiversity, such as adapted mowing management, intercropping of
flowering herbs and the use of sugar dispensers.
Knowledge development takes place through co-creation via farm visits, excursions and exchanges with external experts – including the American organic fruit grower Helen Atthowe. Growers are thus encouraged to adopt a more systems-based approach to their orchard management.
The project is leading to new insights and practical recommendations for more robust organic fruit growing with reduced reliance on organic pesticides.
