Two full season studies were conducted at the Plant Science Research Farm of the Mississippi Agricultural and Forestry Experiment Station, Mississippi State, MS, to determine the efficacy of various insecticides in controlling Heliothis spp. larvae on cotton. Plots were planted with ‘Stoneville 213’ cotton on May 21. All plots were replicated 4 times and were arranged in a randomized complete block design. Each plot was 4 row (0.91 m) x 30.48 m long with 2 buffer rows between plots. Insecticides were applied with a boom-type sprayer calibrated to deliver 56 liters/ha at 2.46 kg/cm through 2 TX-4 nozzles/row.
