NDSU and University of Minnesota Extension Sugarbeet Agronomist Tom Peters is finding waterhemp in a few locations in the southern Red River Valley. Peters says waterhemp is a May weed, emerging right on schedule and is causing a challenge for sugarbeets that are too small to apply a lay-by herbicide. “If we get good rain, we’ll have lots of waterhemp germination and emergence. Farmers need a pre-emergence herbicide out now.” Peters says if we get a half inch of rain or more over the next couple of days, we could see an explosion of waterhemp emergence next week.
