Abstract
These tests were conducted in irrigated spring wheat and barley in fields located near Billings, MT. Plots were 10 ft wide by 30 ft long and were arranged according to a RCB design having 5 treatments with 3 blocks for wheat and 4 treatments with 3 blocks for barley. Insecticides were applied on 3 Jun with a CO2-powered backpack sprayer equipped with a 10-ft hand held spray boom and Teejet 8001 flat fan nozzles. The sprayer was calibrated to deliver 10.5 gal/acre at 20 psi. Insecticide efficacy was determined by counting the number of CLB larvae on each of 50 randomly selected flag leaves from each treated and untreated replicate. Data were subjected to ANOVA, and treatment means were separated by LSD test.
