[Pear psylla: Principles of sustainable management and avoidance of resistance in commercial orchards (IRAC Guideline)]
Nachrichtenblatt des Deutschen Pflanzenschutzdienstes 50 (3), 64-67
Abstract: A principle objective of the Insecticide Resistance Action Committee (IRAC) is to secure a prolonged effective life of reliable insecticides and acaricides. An essential contribution towards achieving this objective, is the development and implementation of resistance management guidelines for specific pests of fruit through IRAC Fruit Crops Working Group (FCWG).
Following the publication of a revised spider mite guideline (Nachrichtenblatt Deutscher Pflanzenschutzdienst, 48, 1996), the FCWG presents a guideline for orientation towards a technically sound resistance management for pear psyllids. Further key pests, in particular Myzus persicae and Aonidiella aurantii, are presently under work.
Besides basic principles of pear psylla management, the guideline confers - classifying the risk of cross resistance - product-related recommendations for control.
The importance of an integrated approach is accentuated through an annexed tabular survey on biological and phenological characteristics of pear psyllids.
