The impact of repeated glyphosate applications on the evolution of glyphosate-resistant Palmer amaranth in cotton will be discussed along with the impact of cultural practices, crop rotation, and herbicide selection on reducing the risk of resistance. The risk of resistance to glyphosate in Palmer amaranth rapidly increases after five years of continuous use of glyphosate.
