AbstractA field study was conducted at the Maricopa Agricultural Center to evaluate the effectiveness of selected defoliant treatments on Pima cotton under warm and cool weather conditions. Dropp was effective as a one application defoliant in September when air temperatures were in the high 90's. In October, when night temperatures were lower, no defoliant tested was effective in a single application.
