| Abstract/Contents: | "Treatment plots were 10 x 8 ft. arranged in a RCB design and replicated 4 times. Dursban formulations were applied by using a CO2 sprayer with 4 8004VS Teejet nozzles mounted on an 8 ft. boom, operating at 28 psi, and delivering 1,146 gal/1,000 square-feet (347 ml/80 square-feet). Insecticidal soap and a combination of insecticidal soap plus Dursban treatments were applied by using a compressed air sprayer with 4 8004VS Teejet nozzles mounted on a 6 ft. boom, operating at 28 psi, and delivering 1.145 gal/ 1,000 square-feet. At treatment time (16 Jul), the following soil and environmental conditions existed: air temperature, 69 degrees F; soil temperature at 1 inch depth, 72 degrees F; soil temperature at 2 inch depth; 64 degrees F; RH, 62%; amount of thatch, 0.125 inches; soil type, sandy loam; soil particle size analysis, 72.0% sand, 20.0% silt, 8.0% clay; soill moisture (oven baked), 14.2%; organic matter 2.8%; water pH, 7.0; soil pH, 6.4; and clear skies. The area was irrigated with 0.08 inches of water 7.5 h after treatment. The total number of fresh active cutworm feeding holes observed on the surface of each replicate (80 square-feet) were recorded on 20 Jul and 22 Jul. An average of 12.0/80 square feet fresh active cutworm feeding joles was recorded on Jul 16 prior to treatment. Eight treatments provided significant control 4 DAT and 6 DAT. Combinations insecticidal soap plus Dursban treatments were effective. No phytotoxicity was noted." |
