This event is free and open to the public.

Ten herbicide programs will be available for comparison to evaluate success and implications for resistance management of weeds including waterhemp, marestail, giant ragweed, and Palmer amaranth. Results of screening of local weed populations for resistance to Roundup, Cobra, and Callisto will be shared.  This year, disease resistance trials will also be available. Treatments were chosen to demonstrate fungicide options and effectiveness.
