Abstract
Abstract Treatments were applied on 25 Jul using a CO2 powered backpack sprayer calibrated to deliver 9.9 gal of finished spray per acre through 8001 nozzle tips at 40 psi. the plots, which were located in Leake County, were 8, 38 inch rows wide by 50 ft long, arranged in a randomized complete block design with 4 replications. Counts were made 3 and 6 DAT by searching the terminal area of 25 plants per plot for larvae; 4 randomly chosen squares from each plant were examined for the damage determination. No rain fell on the plots prior to the 3 DAT sample. Pretreatment infestation level within the plot area was 24% small larvae. Of 37 large larvae collected from check plots and adjacent untreated areas at 6 DAT, 92% were identified as bollworms.
