Evaluation of Alternatives for Early Season Tobacco Budworm Control in Large Plots in Southern North Carolina, 1994

Cotton was planted on 10 May in a Norfolk sandy loam soil near Gibson, NC. Recommended agronomic practices for fertility and weed control were followed and 0.75 lb (AI)/acre Temik 15G was used at planting for thrips. A RCBD with 5 replicates, and 12-row (40 inch centers) × 1,900 ft plots were utilized. Treatments were applied with a John Deere* high clearance sprayer calibrated to deliver 8.0 gpa at 60 psi. The single application was made on 23 Jun. Fifty terminals and squares per plot were inspected for damage and live budworms and ten, 25-sweep samples were taken per plot with a standard 15 inch diam net for budworms on 28 Jun. Data were subjected to ANOVA and DMRT.
