Indiana CCA Conference 2020 Presentation
 

Update on Weed Suppression with Cover Crops

Farmers in the eastern cornbelt are faced with the increasing challenge of controlling weeds that are resistant to more than one herbicide side of action. Over the next 5 years, I believe we will need to incorporate more mechanical cultural and weed control tactics into our currently used herbicide programs. In this presentation I will share results from our research program on the incorporation of cover crops with traditional weed control tactics.
