Defoliation of Pima Cotton at the Safford Agricultural Center, 1992

Abstract

Three defoliation studies were performed on Pima cotton at the Safford Agricultural Center in 1992. One tested two different formulations of Dropp with various adjuvants. The second compared experimental material SN597 with other common defoliants. The third compared SN597 at different rates in a late application. At 14 days after application SN597 dropped 97% of the leaves compared to 37% for sodium chlorate. All of the combinations dropped leaves much more efficiently than chlorate.
