Abstract

Trifluralin-resistant Palmer amaranth populations were confirmed at eight locations within two of the ten-county cotton growing region of South Carolina. Different levels of resistance to six dinitroaniline herbicides were observed, but no resistance was observed to herbicides from nine other chemical groups. Five to six times more trifluralin was required to control a resistant than a susceptible biotype under field conditions.
