Keynote Speaker

Jason Norsworthy is a Professor and the endowed Chair of Weed Science at the University of Arkansas. He grew up on a vegetable farm in southern Ar-kansas, where he quickly learned the need for weed management in crops. Norsworthy has documented eight herbicide-resistant weeds in Arkansas, includ-ing glyphosate-resistant Palmer amaranth. He has been invited nationally and internationally to present his research on management of resistant Palmer amaranth. He presently serves as Editor-in-Chief for Weed Technology, a journal of the Weed Science Society of America that publishes applied weed science research.
