This handbook is intended as a ready reference guide to the control and management tactics for the more important plant diseases in the Pacific Northwest. The specific cultural, biological, and chemical recommendations are intended to manage a specific plant disease but may not always be appropriate under all production circumstances. The synthesis of a specific management recommendation should be done by a qualified individual. For this reason, this book should be used by—and has been expressly written for—county Extension agents, consultants, field and nursery people, and chemical industry representatives. Information in this publication is in a state of constant change.
