For Palmer Amaranth, Two is Better Than One

Mark VanGessel, Extension Weed Specialist;

Our results have consistently shown that two effective active ingredients for Palmer amaranth control provides better residual control than either one by themselves. So consider tankmix partners with your residual herbicide program. In soybeans, metribuzin, Group 15 (i.e. Anthem, Dual, Zidua, Warrant), Group 14 (sulfentrazone [i.e. Authority products or BroadAxe] or flumioxazin [i.e. Valor]), or pendimethalin all look better in combinations. We still recommend use at full labeled rates when tankmixing.
