This web page is a product of the statewide WSU Seed Crop Team, a partnership funded by the CAHNRS Agricultural Extension Issue-Focused Teams Initiative. The team, led by entomologist Doug Walsh and plant pathologist Lindsey du Toit, seeks to protect and enhance the seed industries of Washington State. Other team members include weed scientists Tim Miller and Rick Boydston, plant pathologists Lyndon Porter and Ken Eastwell, Extension educators Tim Waters, Don McMoran, and Carrie Wohleb, and communications specialist Sally O'Neal.

The Seed Crop Team brings faculty and staff from numerous disciplines and both sides of the state together to address issues impacting production of many types of seed crops.
