The test consisted of eleven treatments arranged in a RCB with four replications. Plots were four-38-inch rows x 50 ft. Treatments were initiated based on pretreated TPB counts. All treatments were applied 23 Aug with a CO -pressurized two-man boom at 9.25 gpa. Each plot was evaluated 26 Aug (3 DAT) with two counts from a 3 ft x 3 ft shake sheet placed between the center two rows. Data were processed using Agriculture Research Manager Version 6.0.1. ANOVA was performed and DMRT (P = 0.05) was used to separate means. No treatment provided significant control over the untreated check. However, all treatments had lower TPB counts than the untreated check. The efficacy of Trimax plus Bidrin did not provide enhanced control over Trimax alone. No significance was found among treatments due to the TPB population decreasing between pretreatment and post-treatment evaluations. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Arthropod Management Tests Oxford University Press
