Abstract

On 6 Aug, a soybean efficacy trial was conducted on a commercial farm in Shelby, MS in the Mississippi Delta. Plot size was 12.6 feet wide by 75 ft long planted on 38 inch row centers. Statistical design was a RCB with 4 replications. Insecticides were applied with a tractor-mounted sprayer calibrated to deliver 10.0 gpa at 60 psi through TX-6 Hollow Cone nozzles (19 in nozzle spacing). Treatments were applied on 6 Aug. Estimates of bean leaf beetle density were determined by taking 25 sweeps per plot with a standard 15 inch sweep net 2 and 6 DAT. Data were analyzed with ANOVA and means were separated using a Fisher’s Protected LSD (P ≤ 0.05).
