How Does Roundup Ready™ Cotton Compare to Staple™, DSMA, and Buctril-BXN™ Cotton?

Robert M. Hayes, G. Neil Rhodes, Jr., Claude W. Derting


Field research was conducted during 1994 and 1995 to compare weed management programs using Roundup herbicide and Roundup Ready cotton with Staple, DSMA, and Buctril-BXN Cotton. The research was conducted at Whiteville, TN in 1994 and 1995, and at Jackson and Milan, TN in 1995.

All trials were no-till planted and treatments were replicated three times. All postemergence applications were in water carrier at 10 gpa plus 0.25% Induce surfactant except Roundup that included 0.5% Induce. Post-directed applications were made with hand-held sprayers at Whiteville and with tractor mounted commercial post-direct sprayers at Jackson and Milan. All postemergence overtop applications were to cotton from the 2- to 6-leaf stage and the post-directed treatments were made to cotton with 7 to 12 leaves. All applications were under ideal environmental conditions for optimal activity. Roundup, Staple and DSMA were applied only to Roundup Ready cotton and Buctril was applied only to BXN cotton.
