A field study was conducted at the Maricopa Agricultural Center to evaluate the effectiveness of selected defoliation treatments on Pima cotton under warm and cool weather conditions. Dropp and other defoliants caused desiccation and freezing of leaves when applied at air temperatures above 100° F. Dropp was an effective defoliant when maximum air temperatures were in the low 90s. The experimental defoliant SN 597 NA218 appears to be a promising defoliant for Pima cotton when temperatures are cool.
