With glyphosate-resistant Palmer amaranth becoming more prevalent, TN cotton producers have moved from a glyphosate-based weed management system to a Liberty-based weed management system in the last 5 years. This system includes pre plant, pre emergence and post directed applications of other herbicides besides Liberty to be successful. This system has for the most part controlled weeds particularly Palmer but it is not as inexpensive or easy as when glyphosate still controlled Palmer amaranth.
