NDSU Research Professor Kirk Howatt promotes a multi-faceted approach to managing resistance and weed control. “We have very limited situations where one post-emergent spray will kill the weeds.” Farmers can use a pre-emergence spray to prevent seedling growth early on followed by a post treatment. Later in the season, two applications of post-emergence herbicides can eliminate weed growth. “When it’s small, kill the weeds rather than just stunt them.” Howatt was on the program for the NDSU Wild World of Weeds Workshop.
