A University of Minnesota Extension webinar on weed management covered waterhemp control. “Waterhemp management is easier in corn than soybeans,” said weed scientist Debalin Sarangi. “There are also more tools in the toolbox to deal with resistance. It is very important farmers use a strong foundation for corn and rely on pre-emergence herbicides.” Once there is a good pre-emergence herbicide down, Sarangi says there are multiple post-applied herbicide options to control waterhemp. “For example, the growth regulator herbicides. Sugarbeet growers should also check to see if there are limits on what products can be used.”
