If you are seeing a lot of waterhemp in your fields right now, next year you might consider this layered residual herbicide approach as described by Lisa Behnken, University of Minnesota, Extension Crops Educator, in the video below. Waterhemp populations are ever increasing and further, herbicide resistant is becoming more and more widespread. This include populations resistant to multiple types of herbicide groups. Thus, waterhemp is increasingly difficult to manage. In addition, it has a long emergence pattern and frequently outlasts control of an early preemergence herbicide application. This video explains a two-prong approach.
