Defoliation of Pima and Upland Cotton at the Safford Agricultural Center, 1994

Abstract

Experiments were effected on both Pima and upland cotton to compare the defoliation effects of different rates of Ginstar, Ginstar + Prep and sodium chlorate with an untreated check. Weather conditions after treatment applications were recorded and observations taken after one week and two weeks. Grab samples were taken from the picker to determine percent trash and to run HVI analyses.
