| Abstract/Contents: | "The field plot consisted primarily of Kentucky bluegrass. Treatment plots were 9 x 6 ft, arranged in a complete randomized block design and replicated 4 times. Granular formulations were applied with a hand-held shaker and mixed with blank granules to facilitate product distribution. Liquid formualations were applied by using a CO₂ sprayer with 4 8004VS TeeJet nozzles mounted on a 6 ft boom, operating at 28 psi, and applied in 1021 ml of water/54 ft² or delivering 5 gal/1000 ft². At treatment time (19 May), the following soil and environmental conditions existed: air temperature, 60°F; soil temperature at 1 inch depth, 72.0°F; soil temperature at 2 inch depth, 66.0°F; RH, 69%; amount of thatch, 0.25-0.5 inches; soil textural class, silt loam; soil particle size analysis: 19.0% sand, 57.0% silt, 24.0% clay; organic matter, 4.0%; soil moisture (oven dry weight), 25.5%; water pH, 7.0; soil pH 6.8; application time, mid-afternoon; and skies were partly cloudy. Immediately after billbug control was evaluated by removing four 0.087 ft² sod samples from each replicate, and the total number of bluegrass billbug life stages (larvae, pupae, adults) were recorded from each sample and converted to a ft² count. Sod samples were removed with a 4-inch cup cutter. Billbug infestations caused major damage to the experimental area in 1994. Bluegrass billbugs were actively observed on the experimental area prior to treatment based on pitfall counts. The ANOVA was not significant (P=0.5). No phytotoxicity was noted." |
