Field experiments were conducted at six locations in North and South Carolina, Georgia, and Florida to evaluate soil and postemergence herbicide systems for cotton tolerance, thrips control, weed control, and cotton yield in BXN cotton. Treflan applied at 0.5 lb ai/ac preplant incorporated (PPI) and Bladex at 0.8 lb ai/ac plus Bueno 6 at 2.0 lb ai/ac applied at LAYBY were blanket treatments for all plots. Herbicide systems were composed of a factorial arrangement of PRE (preemergence) and early postemergence (EPOST) treatments. PRE herbicide options were 1) none, 2) Zorial at 0.75 lb ai/ac PPI fb (followed by) Zorial at 0.75 lb/ac PRE [hereafter referred to as Zorial split], 3) Cotoran at 1.5 lb ai/ac PRE, 4) Zorial split plus Cotoran at 1.5 lb/ac PRE, 5) Zorial at 1.5 lb/ac plus Cotoran at 1.5 lb/ac PRE, and 6) Command at 1.0 lb ai/ac plus Cotoran at 1.5 lb/ac PRE. EPOST herbicide options included 1) none, 2) Buctril at 0.5 lb ai/ac EPOST, 3) Staple at 0.063 lb ai/ac EPOST, and 4) Cotoran at 1.0 lb/ac plus MSMA at 2.0 lb/ac early post-directed (EPDS). EPOST and EPDS herbicides were applied when cotton was 4 to 6 inches tall. Di-Syston was applied in-furrow when Command was applied PRE. All other treatments received Temik in-furrow for early season insect control. Staple was applied with a nonionic surfactant at 0.25% (v/v). Herbicides were applied at 15 to 20 gpa with backpack and tractor mounted booms. Standard small plot research methodology was used at all locations.
