There’s a breakdown of pre-emerge herbicides this spring, allowing pigweeds to flourish. It is unknown why the chemicals did not activate properly. “One good indicator of activation is the nurse crops. I’ve walked some fields where we should have done some damage to them,” said Tom Peters, sugarbeet agronomist, University of Minnesota and NDSU Extension. “If they’re healthy, I guess we can kind of figure out why we’re starting to see some waterhemp.” Peters says the next step is to manage the escapes. “We don’t want them to grow, but with the warm temperatures, they will grow. We’ll figure out what happened later on.”
