2021 Giant Ragweed Management Plot Tour

We are pleased to announce our 2021 WiscWeeds Giant Ragweed Management Plot Tour (June 11, 2021 from 10:00AM to noon at Rock County Farm).

Rock County Farm address: 200 US-14, Janesville, WI.

Giant ragweed is ranked as the 2nd most troublesome weed species in Wisconsin row crop production according to our recent surveys. To learn more about giant ragweed management in corn and soybean, join us for a tour of our research plots at the Rock County Farm showcasing comparison of multiple PRE and POST-emergence herbicide programs and cereal rye cover crop. Come prepared to gather you own data on giant ragweed control and collect good images from our studies!
