Weed management in conventional and no-tillage cotton using BXN, Roundup Ready, and staple OT systems

Buctril, Roundup, and Staple have different weed control spectrums and thus, different needs for supplementary soil-applied or layby herbicides. All three herbicides allow no-till cotton production. Deciding which system is correct depends on the target weed spectrum, suitability of available cotton varieties to the growing region and tillage system, and herbicide-resistance management and carryover in rotational crops. Studies were conducted in 1997 and 1998 at two North Carolina locations to evaluate herbicide systems using Buctril, Roundup Ultra, and Staple in conventional and no-tillage cotton for weed control and cotton response and yield.
