2021 WSU Weed Control Reports Now Available

The 2021 WSU Weed Control Report is now available on the Wheat and Small Grains website. Drew Lyon and Ian Burke, WSU weed scientists, manage numerous field studies to evaluate new herbicides, and new uses of older herbicides, to manage weeds of concern to dryland farmers in eastern Washington. Their research is partially funded by the Washington Grain Commission, USA Dry Pea and Lentil Council, Washington Oilseeds Commission, Washington State Commission on Pesticide Registration, Otto and Doris Amen Dryland Research Endowment, The Washington Turfgrass Seed Commission, and the Organic Research Extension Initiative. These studies are summarized in the annual WSU Weed Control Report.
The 2021 report summarizes 20 field studies conducted across eastern Washington in winter wheat (5 studies), spring wheat (4 studies), chemical fallow (7 studies), winter peas (1 study), spring canola (1 study), weed seed bank management (1 study), and includes the precipitation records for Pullman and Davenport, Washington.
