Treatments were applied on 11 Apr on ‘Magnum’ variety winter wheat in Lonoke County, AR. Treatments were applied with a CO2 powered backpack sprayer with a 10-ft boom equipped with TX-4 hollow cone nozzles on a 19-inch spacing. The sprayer was calibrated to deliver 10.5 gal/acre at 40 psi. Plots were 10-ft wide by 20-ft long arranged in a RCB design with 4 replications. Plots were evaluated at 2 and 7 DAT by counting the number of greenbugs in a 2-ft section of row in each plot.
