| Abstract/Contents: | "Treatment plots were 6 x 10 ft, arranged in a RCB design and replicated 4 times. Granular formulations were applied with a hand held shaker with top-dressing sand used to provide even ditribution of product. At treatment time (17 Jul), the following soil and environmental conditions esisted: air temperature, 72° F; soil temperature at 1-inch depth, 73° F; soil temperature at 2-inch depth, 69° F; RH, 84%; amount of thatch, 0.0625 inch; soil textural class, sandy loam; soil particle size analysis: 58.6% sand, 30.1% silt, 11.3% clay; soil percent water weight (percent by weight), 17.5%; organic matter, 5.0%; water pH, 7.0; soil pH, 6.8; time of application, early morning; and clear skies. The entire area was irrigated with 0.25 of water immediately following application of granules. A total of 8.85 inches of rainfall or irrigation was recorded from 17 Jul through 5 Aug. Treatments were applied on 17 Jul following artificial infestation of the research area with second- and third-instar Black cutworm larvae on 15 Jul. Efficacy data was recoreded on 20 Jul, 25 Jul, 3 Aug, and 6 Aug 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 30 ml Lemon Joy^D]T^D]M dishwashing detergent in 2 gal of water. An average of 12.2 larvae/sq yd was recorded on 15 Jul. A second infestation with second- and third-instar black cutworm larvae was recorded on 30 Jul as part of the experiment's residual study protocol, resulting in an avg of 12.5 larvae/sq yd. The entire experimental area was covered with bird netting from 15 Jul through 20 Jul. The area was recovered with bird netting following the second artificial infestation on 30 Jul and remained covered through 3 Aug. All treatments sampled through 3 Aug provided significant reduction of black cutworm larvae. No phytotoxicity was noted." |
