Tolerance and Efficacy using Herbicide Combinations in Stacked Glufosinate/Glyphosate Tolerant Cotton

Cotton tolerance to glyphosate and glufosinate tank mix combinations was confirmed at several field locations in Texas.  Additional tests in non-crop areas were conducted to investigate the efficacy of glyphosate + glufosinate in tank mix combinations at different ratios of the two herbicides on control of Palmer amaranth and ivyleaf morningglory.  Field studies looking at the importance of order of application also were conducted for Palmer amaranth control.  A discussion regarding the potential fit for this new technology will also be discussed.
