This test was conducted on a field of'Chisholm' wheat located in Noble County which had been planted on 6 Oct 1990. Pretreatment sampling indicated an infestation level of 2.17 larvae/linear row ft. Treatments were applied 28 Feb using a ground rig which was calibrated to deliver 20 gal/acre at 20 psi, traveling 3.5 mph. Plots were 15 × 100 ft and were arranged in a randomized complete block design with 4 replications. The no. of army cutworm larvae/row ft was determined by examining soil and plant material in 3 subsamples per plot. Each subsample consisted of 6 linear row ft.
