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.

Laurel wilt is a disease of woody plants in the laurel family (Lauraceae). Hundreds of millions of redbay (Persea borbonia) trees have been killed by laurel wilt in the southeastern Atlantic Coastal Plain region of the United States (US). The disease has also killed large numbers of sassafras (Sassafras albidum) trees in forests and landscapes, and avocado (Persea americana) trees in commercial production. As of October 2019, laurel wilt was known to occur from Texas to North Carolina, south through Florida and north to Kentucky. Laurel wilt is expected to continue spreading through sassafras in the eastern US, and is a potential threat to California bay laurel (Umbellularia californica) in the western US and to lauraceous species elsewhere in the world.

How do Great Lakes water levels affect expansion and management? This geonarrative aims to provide land managers, decision makers, and the public with a historical perspective on the influence of water levels on Phragmites expansion and to identify Phragmites populations best suited for management in high water.
