IPM in Washington

With a firm foundation of laboratory and applied research, faculty and staff of WSU communicate the latest in crop protection and sustainable pest management tactics to our state's agricultural producers and other end users.

Agricultural IPM

Washington State produces over 300 agricultural commodities, and WSU's researchers and extension professionals serve many of them. From field crops to seed crops, small fruits to tree fruits, this site contains information on a wide variety of IPM tactics. The next time you tuck into a green salad, ribeye steak, and a glass of Cabernet Sauvignon, thank the lettuce seed, beef cattle, and wine grape specialists at WSU.

Urban IPM

Integrated pest management touches our lives in our homes, our offices, and our children's schools. Indoors and outdoors, it's a concern wherever people and pests live in proximity. Innovative, research-based training programs developed and delivered by WSU's urban IPM specialists are addressing urban IPM all across Washington State.

Fly Dispersal Article Published

Researchers at WSU's Irrigated Agriculture Research and Extension Center (IAREC) in Prosser conducted studies on fly dispersal utilizing a protein-based marker to track sex-specific dispersal distances of over 600 flies. Those results, and their implications for rotational grazing and other IPM strategies are discussed in the article "Use of a Highly Sensitive Immunomarking System to Characterize Face Fly (Diptera: Muscidae) Dispersal from Cow Pats" in the February 2014 issue of the journalĀ Environmental Entomogy.
