In organic apple growing the woolly apple aphid (Eriosoma lanigerum) is still an unsolved
problem. Various approaches to use beneficial insects were not really effective. Only
winter treatments with mineral oils showed partial and fluctuating success.
In 2006 and 2007 field trials were carried out to evaluate the efficacy of winter treatments
to control woolly apple aphids. The efficacy of several products (different mineral oils, lime

and possible side effects on the population of predatory mites were investigated. The
study furthermore aimed at establishing the best timing of the application against the target
