Integrated Pest Management Strategic Plan for Hazelnuts in Oregon and Washington

Katie Murray and Paul Jepson

EM 9223

Growers, commodity-group representatives, pest-control advisors, processors, university specialists, and other technical experts from the hazelnut industry in Oregon and Washington assembled this plan, which outlines major pests, current management practices, critical needs, activity timetables, and efficacy ratings of various management tools for specific pests in hazelnut production. The result is a strategic plan that addresses many IPM and pest-specific critical needs for the Oregon and Washington hazelnut industry.

Sustainable Hazelnut Production: Filbertworm Control by Mating Disruption

Betsey Miller, Daniel Dalton, Linda Brewer and Vaughn Walton

EM 9198

Filbertworm is the insect pest of greatest economic importance in Oregon hazelnut production. This publication explains how to Implement mating disruption as a strategy that will reduce damage caused by filbertworm feeding. A mating disruption strategy reduces pesticide applications and protects natural enemies of secondary hazelnut pests such as filbert and hazelnut aphid.
