| Abstract/Contents: | "Treatment plots were 10 x 8 ft, arranged in a RCB design, replicated 4 times. Liquid formulations were applied by using a CO₂ compressed air sprayer with 6 8002VS TeeJet nozzles mounted on an 8 ft boom, operating at 28 psi, and applied in 756 ml of water/80 ft² or delivering 2.5 gal/1,000 ft². At treatment time (24 Jul), the following soil and environmental conditions existed: air temperature, 75°F; soil temperature at 1 inch depth, 78°F; soil temperature at 2 inch depth, 74°F; RH, 83%; amount of thatch, 0.125 inch; soil textural class, loamy sand; soil particle size analysis: 80.0% sand, 11.5% silt, 8.5% clay; soil moisture (oven dry weight), 31%; organic matter, 3.4%; water pH, 7.0; soil pH, 6.6; time of application, early morning; and overcast skies. The area was irrigated in with 0.1 inch of water immediately after treatment (24 Jul). Efficacy data was recorded 3 DAT and 7 DAT by counting the number of black cutworm larvae flushed to the surface within a 1.0 yd² wood frame sampling area using a soap irritant drench of 15 ml Lemon Joy™ dishwashing detergent in 2 gal of water. An average of 5.0/yd² cutworm larvae was recorded on 24 Jul prior to treatment. All treatments significantly reduced black cutworms. No phytotoxicity was noted." |
