NDSU Extension Weed Specialist Joe Ikley says some broadleaf weeds had an early start. “We had about two weeks of spring and then right into summer; some of our weeds, like kochia, were were up early and are still continuing to be a problem.” Rainfall will determine the next step. “If we got a preemergence residual herbicide put on over the top that didn’t have rain to incorporate it, those fields could be somewhat problematic moving forward.” Ikley said that may trigger a post-emergence application earlier than would be seen in a typical year.
