Manage waterhemp in soybean with layered residual herbicides

Lisa Behnken, Extension Educator, Fritz Breitenbach, IPM Specialist SE Minnesota, Jeff Gunsolus, Extension Agronomist, Weed Science, and Phyllis Bongard, Content Development and Communications Specialist, University of Minnesota With waterhemp becoming more widespread and herbicide resistant populations expanding, including multiple-resistant populations, waterhemp is increasingly difficult to manage. In addition, it has a long emergence pattern and frequently outlasts control of an early preemergence herbicide application. One strategy is to layer residual herbicides to control glyphosate-resistant waterhemp by extending the duration of seedling control.
