Abstract

Weed control is a limiting factor for adoption of conservation tillage systems on the Texas Southern High Plains. A field study was established to evaluate Palmer amaranth control with strip-tillage dinitroaniline herbicide incorporation in wheat residue. Preemergence herbicides were applied alone and in combination with strip-tilled incorporated herbicides. Significant cotton injury or stand reductions were not observed with any treatment. Effective (>80%) early season Palmer amaranth control was achieved with trifluralin or pendimethalin in conjunction with preemergence herbicides. Preemergence herbicides alone did not provide adequate control.
