Weed Science Research at WSU

Weed control research at Washington State University focuses on managing a changing weed spectrum through development of integrated weed management strategies that use a variety of approaches including: chemical, cultural, mechanical, and biological methods. Weed scientists in the Crop and Soils Sciences Department work in dryland wheat production systems in eastern Washington, irrigated annual cropping systems and perennial tree and vine crop systems in the Columbia Basin, and rainfed berry and ornamental plant production systems in western Washington. Weeds research is conducted in laboratories, greenhouses, growth chambers, WSU field research stations located across the state, and on grower fields, orchards, and ranches.
