Abstract
Abstract Cotton was planted on 25 Apr in a Marlboro fine sandy loam soil near Johns, NC. Fertility and weed management programs followed NCSU recommendations with 0.75 lb (AI)/acre Temik 15G applied in furrow at planting. Plot size was 6 rows (38 inch centers) × 50 ft with 8 ft alleys. A RCBD with 5 replicates was used. Treatments were applied with a backpack-type CO2-pressurized sprayer calibrated to deliver 8 gpa at 50 psi with a single TX-8 Spraying Systems* nozzle per row. The single application was made on 6 Jun. On 27 Jun, 25 terminals and squares per plot (125 per treatment) were inspected for damage and live TBW. On 1 Aug all bolls were counted on 15 ft of row per plot (75 ft per treatment). Data were subjected to ANOVA and DMRT.
