Abstract
Abstract The efficacy of selected insecticides for control of VBC was evaluated in 3 small plot insecticide trials at the St. Gabriel Research Station near St. Gabriel, LA. Treatments in all 3 tests were applied to ‘Buckshot 723’ soybean in the R5 growth stage using a tractor and compressed air sprayer calibrated to deliver 93.5 1/ha at 2.66 kg/cm2 through 8002 flat fan nozzles. Plots in all tests were 5 rows wide (0.91 m row spacing) by 15.2 m, arranged in a RCBD with 4 replications. At 2 and 7 DAT in each test, one 25 sweep sample was taken from each plot with a standard 38.2 cm diam sweep net. Test 1 was applied 6 Sep, Test 2 was applied 8 Sep, and Tesi 3 was applied 14 Sep.
