Glyphosate-resistant Palmer amaranth caused many Georgia growers to go back to deep tillage in order to use pre-plant incorporated herbicides. The Univ. of GA, USDA-ARS, Auburn Univ., Clemson Univ. and the Univ. of TN developed a program using high-reside cover crops, strip-till equipment, and herbicides with different mechanisms of action to provide good control of weeds that commonly occur in cotton. The video, made by the Univ. of GA, illustrates a strip-till program using fall-planted cereal rye to suppress weeds, conserve soil, and reduce input costs.
