TARNISHED PLANT BUG CONTROL ON COTTON WITH NEW INSECTICIDES, 2001

Treatments were arranged in a RCB design with four replications. Plot size was four 38-inch rows x 50 ft. The treatments were applied on 26 Jul with a CO -pressurized backpack sprayer. The boom contained conejet TXVS-6 nozzles on a 19- inch spacing. Operating pressure was 35 psi with a final spray volume of 12 gpa. Plots were evaluated on 30 Jul (4 DAT) and 2 Aug (7 DAT). Drop cloths were used to determine TPB populations in 24 row-ft/plot. Data were processed using Agriculture Research Manager Version 6.0.1. ANOVA was conducted and DMRT (P = 0.05) was used to separate means only when AOV Treatment P(F) was significant at the 5% level. All insecticides were statistically similar and significantly reduced TPB numbers when compared to the untreated check at 4 DAT. TPB counts ranged from 0.3-2.3/24 row-ft or 83-98% control. By 7 DAT, the TPB population in the untreated check had fallen by 74%-3.5 TPB/24 row-ft, and there were no significant differences among treatments. On a numerical basis only, all treatments at 7 DAT had a lower TPB population than the untreated check. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Arthropod Management Tests Oxford University Press
