Most row crop producers in Alabama have adopted some form of conservation-tillage and are challenged with controlling resistant Palmer amaranth or horseweed (marestail) in their crop rotation. Controlling resistant Palmer amaranth and horseweed within soybean is currently feasible due to effective preemergence and post emergence herbicide options, yet it can be a challenge due to lack of preemergence herbicide activation or poor post emergence activity due to dry conditions at time of application. Current Palmer amaranth recommendations throughout the Southeast and Mid-south are designed to reduce the seedbank. Because glyphosate resistance is increasingly a problem in Alabama, effective...
