EVALUATION OF INSECTICIDES FOR CONTROL OF CORN EARWORM ON SNAP BEAN, 2002

Roma II snap bean had been planted into 30 inch rows on 13 Apr 2002. Plot size was five rows 60-ft long. A single non-treated row separated plots. Experimental design was RCB with four replications. Insecticides were applied on 31 May with a bicycle sprayer equipped with 10 TeeJet 80015 nozzles. The sprays were propelled with compressed CO at 25 psi and the resulting spray volume was 7.3 gpa. Average pod size at application was 2 inch. Insecticide effectiveness was assessed 7 DAT by randomly selecting a 10-ft length of the center row and counting the number of non-damaged and insect damaged pods within the sampled area. Data were analyzed with ANOVA and means were separated with LSD. Damage resulting from Corn earworm (CEW) feeding was moderate with 11.2 damaged pods per 10 row ft. All insecticide treatments significantly reduced the number of CEW damaged pods below the number of damaged pods in the non-treated plots. In plots receiving Fury, Capture or Warrior, no pods damaged by CEW were detected. No significant difference was detected in number of non-damaged pods. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Arthropod Management Tests Oxford University Press
