Oregon Weed Science Society is a non-profit organization founded in 1951 dedicated to promoting weed science scholarship, education, and knowledge dissemination. Our primary goal is to put on a yearly meeting for growers, agronomists, and weed scientists. This meeting highlights new research, practical in-field applications, new product updates, and current topics.
We are community of Weed Scientists and Weed Managers.
- To foster and encourage education and research in weed science.
- To foster cooperation among state, federal and private agencies in matters of weed science.
- To aid and support commercial, private and public agencies in the solution of weed problems.
- To support legislation governing weed control programs and weed research and education programs.
- To support the Weed Science Society of America and foster state and regional organizations and agencies interested in weed control.
