Abstract

The use of Roundup Ultra in Roundup Ready Cotton has provided new opportunities to control many troublesome weeds. Experiments were conducted at Lubbock and New Deal, TX to investigate cotton tolerance, weed control, and yield in Roundup Ready Cotton. Roundup Ultra at 0.75 lb ae/A was applied postemergence-topical (PT) at the 1- or 4-leaf stage or postemergence-directed (PD) at the 10- or 14-leaf stage in 1996 or PT at the 2- or 4-leaf stage or PD at the 6- or 8-leaf stage in 1998. Sequential applications of two, three, and four applications were made each year. In separate studies, Roundup Ultra was applied at 8 nodes above cracked boll (NACB), 4 NACB, and at 20% open boll. Plots were kept weed free and managed intensely for insects.
