Abstract
Abstract A 10-yr-old stand of alfalfa located at the Main Station Field Laboratory, Reno, NV was used for this study. Treatments were applied when alfalfa was 14-16 inches tall with 30-40% of terminals showing alfalfa weevil damage. Plots were 25 × 50 ft with treatments replicated 4 times in a randomized complete block design. Sprays were applied with a CO2 activated bicycle plot sprayer calibrated to deliver 18.5 gpa at 35 psi. Treatments were on May 24 and posttreatment samples were taken on May 27, 31 and jun 7, 14 and consisted of 10 sweeps of a standard net taken at random from each replicate. Conditions at treatment were calm, sunny and 78°F. No measurable precipitation occurred during study period.
