With postemergence herbicide supply issues creating challenges for 2022 and possibly into 2023, using a preemergence herbicide with residual activity as part of a weed management program is as important as ever. Preemergence herbicides can aid in the control of troublesome weeds such as waterhemp and giant ragweed. They can also result in lower weed densities and a more uniform weed height at the time of postemergence herbicide application, aid in the management of herbicide-resistant weeds, and ultimately help protect crop yield potential and profitability. What if you want to plant a cover crop later in the season? Will a residual herbicide that controls weeds also affect your cover crop?
