Abstract

Dinitroaniline herbicides have been used on the Texas Southern High Plains since the mid-1960s. Over this same period, cotton yields in this region have declined in spite of improved varieties and technology. Repeated applications of trifluralin and pendimethalin, each applied at 1x and 2x rates, were incorporated in 1983 through 1988. Variations in cotton stands, yields, and fiber quality were high due to environmental conditions. After six repeated applications, no reductions in cotton growth or yield were observed, even at the highest rates.
