Summary: The goal of this project was to test multiple strategies and contributing factors to improve IPM programs for pear pests, mainly pear psylla. This project examined cultural controls such as reflective mulches and particle films, chemical insecticide efficacy, non-target effects of insecticides on natural enemies and full season programs. Additionally, a key element of this project was to provide research findings to industry stakeholders in real-time. This was accomplished through the development and updating of the WSU Tree Fruit Pear IPM website, writing newsletter articles in the WSU Extension newsletter Fruit Matters, and by delivering presentations at over 45 stakeholder events.
