| Abstract/Contents: | "This trial was completed on a bentgrass green maintained at the Penn State Valentine Turfgrass Research Center at University Park to determine product performance against third and fourth instar BCW larvae. Treatment plots were 6 X 8 ft, arranged in a RCB design and replicated four times. Eight inch diam by six inch long white PVC cylinders were placed in each replicate and secured in place. One cylinder was placed in each replicate per evaluation period (7 Aug, 9 Aug, 13 Aug). Ten 0.75-1.0 inch black cutworm larvae were placed in each cylinder on 5 Aug. Bird netting was placed over the experimental area from 5 Aug through 13 Aug to prohibit bird predation. Liquid formulations were applied by using a CO₂ compressed air sprayer with 4 8002VS TeeJet nozzles mounted on a 6 ft boom, operating at 28 psi, and applied in 363 ml of water/48 ft² or delivering 2.0 gal/1,000 ft². At treatment time (6 Aug), the following soil and environmental conditions existed: air temperature, 64°F; soil temperature at 1 inch depth, 62°F; soil temperature at 2 inch depth, 62°; RH, 80%; amount of thatch, 0.0625 inch; soil textural class, loam; soil particle size analysis: 48.3% sand, 42.9% silt, 8.8% clay; soil percent water content (percent by wt), 22.7%; organic matter, 4.0%; water pH, 7.0; soil pH, 6.6; time of application, early morning; and partly cloudy skies. A totalof 2.5 inches of rainfall or irrigation was recorded from 7 Aug through 13 Aug with 2.0 inches rainfall recorded from 9 Aug through 13 Aug which resulted in flooding of research area. Efficacy data was recorded on 7 Aug, 9 Aug, and 13 Aug by counting the number of BCW larvae flushed to the surface withing each PVC cylinder by using a soap irritant drench. An average of 7.75 larvae/50 inch² was recorded on 6 Aug. Three treatments provided significant control on 7 Aug, seven treatments provided significant control on 9 Aug, but no treatments provided significant control on 13 Aug which may be the result of flooding from excessive rainfall. No phytotoxicity was noted." |
