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 […]

Codling moth (Cydia pomonella): Control methods in organic fruit production

Codling moth (Cydia pomonella) is the primary pest in organic fruit growing. It damages apple, pear, quince, rowan, medlar, walnut and kaki. Generations/years vary depending on the soil and climates zones. Several control methods can be applied in organic farming depending on the infection rate, but plant protection products and mating disruption are the most […]

Apple scab (Venturia inaequalis): Control strategy for organic pome production

Apple scab is the primary fungal disease in apple cultivation affecting entire harvests as well as the following year’s production. The damage can occur both in the plant and during storage. In organic farming, scab control is mostly carried out using precautionary measures. Plant protection products are used for direct control before the onset of […]

Regulation of sawflies in organic orchards

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 […]
