Influence of Spray Tip and Herbicide Program on Palmer Amaranth Control

Palmer amaranth (Amaranthus palmerii) has become one of the most troublesome weeds for cotton producers in the southeast.  As the population of glyphosate resistant Palmer amaranth has increased, other modes of action have been evaluated to help control this troublesome weed. This study looks at the efficacy of dicamba, glufosinate, and glyphosate on Palmer amaranth.  Along with the herbicide programs, tip selection was also evaluated.
