Direct regulation of the black cherry aphid in organic table cherry production
The black cherry aphid (Myzus cerasi) is the main pest in modern organic table cherry production. In orchards with installed rain protection and insect nets, robust aphid populations can build up, leading to significant yield losses and tree damage. The black cherry aphid can be indirectly and directly regulated. This practice abstract gives recommendations for […]
Rosy apple aphid (Dysaphis plantaginea) management in organic fruit production
Rosy apple aphid can lead to up to 95% yield losses. Damage is caused by growth paralysis of the buds and fruit and high production of honeydew, which can cause sooty mould. The most effective management methods in organic production are preventive agronomic measures and direct control using products based on Neem (Azadirachta indica) extracts. […]
Preventive and indirect measures to regulate woolly apple aphid in organic orchards
The Woolly apple aphid (E. lanigerum) can cause severe damage, especially in organic cultivation; sucking activity causes bark growth, the so-called blood louse canker. Promoting natural antagonists in organic orchards is a key element in controlling E. lanigerum. Further, the tree growth should be balanced through proper (root) pruning. A combination of preventive measures and […]

Rosy apple aphid: Direct control with Neem in organic orchards
Project BioFruitNet – Rosy apple aphid (Dysaphis plantaginea) has a fast reproduction cycle and the potential to cause major damage in orchards. Preventive measures such as promoting beneficial insects and pruning are often not sufficient. Direct control with Azadirachtin (NeemAzal®-T/S, also called Neem) decimates the population and keeps damage below the economic damage threshold. Neem […]
