Speaking at the NDSU Extension weed plot tour, NDSU weed scientist Kirk Howatt said there are not many post emergence options to control waterhemp. “Many of them are Group 2 or ALS products that waterhemp has developed resistance to. We are conducting research trials to see if we can work on special labeling to keep waterhemp from dominating the cereals.” Kochia has been another troublesome weed to control this season. “Because of the weather patterns, it seemed to be hardened off and hard to control, even when it was two inches tall.”
