The soybean growers in Nebraska and across the U.S. have just been thrown a curveball, as a federal court in Arizona vacated registration of dicamba formulations specific for use on dicamba tolerant soybeans (including Xtendimax, Engenia, and Tavium), finding that the Environmental Protection Agency (EPA) failed to meet regulatory requirements. Dicamba is still an effective weed control option, particularly when it comes to Palmer amaranth.
