The following is a brief summary of new products available for weed control in corn and soybean in 2021. None of these are new sites of action herbicides, but are new premixes or revised formulations of existing active ingredients. With growing concerns of weeds developing resistance to herbicides, especially waterhemp with confirmed 4-5 way resistance to herbicide groups, HGs 2 (ALS inhibitors), 5 (atrazine), 9 (glyphosate), 14 (PPO inhibitors), and/or 27 (HPPD inhibitors) in Iowa corn and soybean fields (2019 survey), it is important to consider multiple effective sites of action herbicides both in postemergence and preemergence (soil residual) herbicide programs.
