Abstract

Despite the importance of glyphosate-based crop systems, there is a need for continued understanding about the management requirement for weed control in continuous corn production. The concern for timely weed management in order to protect corn yields becomes premier in postemergence (POST) herbicide corn systems, whether based on glyphosate or any other herbicide. Iowa State University recommends the use of herbicides that provide residual weed control in continuous corn regardless of the specific GM trait. The early preplant (EPP) or preemergence (PRE) application of residual herbicides is an excellent option to reduce weed management risks, improve environmental stewardship, and better utilize time at a critical period of the spring.
