Glyphosate-resistant Palmer amaranth was confirmed in Macon County, Georgia in 2005. Dryland cotton producers have struggled with managing this pest due to erratic rainfall that is essential for the activation of residual herbicides. This field experiment evaluated glyphosate-resistant Palmer amaranth and cotton response to residual at-plant herbicides applied on the soil surface or preplant incorporated.
