Protoporphyringogen oxidase (PPO) inhibitor herbicides are widely used for postemergence and residual weed control and the management of glyphosate-resistant weeds in soybeans. Tall waterhemp, common ragweed, and Palmer amaranth have evolved as PPO-resistant weeds in many parts of the country. Best management practices are needed to manage resistant weeds and preserve the effectiveness of PPO herbicides for use in soybeans.
