Waterhemp remains the number one problem weed in Minnesota and across the Midwest. The evolution of herbicide resistance has made its control increasingly difficult in agronomic cropping systems. Based on years of research and on-farm experience, a preemergence herbicide remains the cornerstone for effective waterhemp management. However, due to the weed’s extended emergence window, season-long control can be challenging. Layering residual herbicides—an approach that involves applying overlapping soil residuals—has proven to be one of the most effective strategies to address this issue. This presentation will discuss the advantages, limitations, and practical considerations of the layered residual approach for waterhemp control. In addition, non-chemical tactics such as Harvest Weed Seed Control (HWSC) will be highlighted as one of the tools within an integrated weed management framework to manage herbicide-resistant weeds in U.S. agronomic crops.
