Nine defoliation treatments were applied to Pima and upland cotton to compare the treatment effects on percent leaf drop, trash sent to the gin, lint yields, percent lint turnout and percent first pick. All of the treatments were beneficial to leaf drop compared to the untreated check with the Ginstar treatments generally performing better than the others. The addition of nonionic surfactants and drift retardants seemed to reduce the activity of Ginstar. Yield differences on long staple treatments were notices and discussed in the paper.
