Studies were conducted in 2007 at the Texas Agricultural Experiment Station in Lubbock, to evaluate several postemergence herbicides on volunteer glyphosate-tolerant cotton.  Applications were made to cotton at the 4 to 5 leaf and 10 to 12 leaf growth stages.  Early treatments , including Aim, ET, and Buctril were effective controlling volunteer glyphosate-tolerant cotton, while late applications were less effective.
