Bollgard II XtendFlexTM Cotton Weed Management Systems in the Texas High Plains

This research examined weed management systems in dicamba/glyphosate/glufosinate-tolerant cotton.  Fifteen weed management “systems” were examined that include a variety of soil residual and postemergence treatment combinations.  Two weeds, glyphosate-susceptible Palmer amaranth and Texas millet, were the dominant weeds in this drip-irrigated field.  Cotton injury was examined following each application as well as weed control.  Cotton was plant mapped and yield and grade was determined at the end of the growing season.
