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.
