Weed Resistance to Herbicides in Cotton Production: Summary Results From a Farmer Survey

Weed resistance to herbicides has become a very serious problem for U.S. cotton producers, and weed resistance is spreading across cotton growing regions. This problem currently affects or will affect almost all cotton producers. It costs farmers millions of dollars annually in lost yields and weed control costs. This presentation will report preliminary summary results from a mail survey of cotton farmers in 2012 about their problems with resistant weeds. The presentation will describe how production practices, weed control costs, and yields of cotton farmers in the survey sample have changed because of weed resistance problems.
