Minimising moth damage in apple orchards in a cost-efficient way
(István Ujvári)
The core of apple pest management is codling moth control. Successful chemical control against it can be achieved only by targeted treatments with proper timing. However, it may imply even 10-18 insecticide treatments annually that, in addition to enormous costs, raise the issue of risks by pesticide residues. Having all these in mind, the article describes mating disruption with pheromones as a prospective method available also in Hungary since 2007, its mode of action and the necessary appliances. Finally, as a novelty of the year, the author presents a new product with new mode of action, containing Cydia pomonella granulosis virus. This helps considerably reduce the number of insecticide treatments and increase the efficacy of controlling codling moth.

We wish to increase the knowledge of growers in pest management by presenting the major pests and diseases and the methods to control them, hoping that all these will give stimulus to establishing quince orchards.
