Non-2,4-D Tolerant Cotton Response to Drift and Tank Contamination

Drift and tank contamination of 2,4-D in cotton has always been a concern in the Texas High Plains as corn and sorghum are also grown in the region. Growers are aware that selection of proper equipment, good application techniques, and thorough cleaning of spray systems following herbicide applications all contribute to minimizing drift and tank contamination, but the extreme sensitivity of cotton that is not tolerant to 2,4-D needs to be properly documented to illustrate this concern. This study will examine the risk of drift and tank contamination following an application of 2,4-D in non-2,4-D tolerant cotton.
