Abstract/Contents: | "This study was undertaken to determine suppression of BB on turfgrass maintained at Penn State's Valentine Turfgrass Research Center at University Park. The turfgrass area consisted primarily of Kentucky bluegrass (100%). Treatment plots were 8 x 6 ft, arranged in a RCB design and replicated three times. Granular formulations were applied with a hand-held shaker and mixed with fine top dressing sand to facilitate product distribution. At the first treatment time (7 May), the following soil and environmental conditions existed: air temp, 69°F; soil temp at 1 inch depth, 68°F, soil temp at 2 inch, 64°F; RH, 80%; amt of thatch, 0.25-0.5 inch; soil percent water content (percent by wt), 11.4%; water pH, 7.0; application time, late afternoon: and partly cloudy skies. Immediately after application, the treatments were irrigated with 0.15 inch of water. At the second treatment time (18 Jun), the following soil and environmental conditions existed: air temp, 72°F; soil temp at 1 inch depth, 74°F; soil temp at 2 inch, 66°F; RH, 50%; amt of thatch, 0.25-0.5; soil percent water content (percent by wt), 15.2%; water pH, 7.0; application time, early afternoon; and partly cloudy skies. Immediately after the application, the treatments were irrigated with 0.1 inch of water. The experimental area was irrigated as and when needed throughout the summer because of drought conditions. General soil conditions were as follows: textural class, silt loam; soil particle analysis, 20.8% sand, 52.6% silt, 26.6% sand; % water content (% by wt), 11.4; soil organic matter, 5.2%; and soil pH, 7.3. Posttreatment counts were made on 24 Jun. Three 4-inch cup cutter sod samples were randomly taken from each replicate. The total numbers of BB larvae recovered from three 4-inch cup cutter sod samples were recorded and converted to a 3ft² count. Each replicate was evaluated for turf quality by utilizing a color rating of 1-10 where 1 = off color and 10 = dark green on 25 Jun and 7 Jul. Adult billbugs were actively recovered from pitfall traps positioned at the experimental site prior to treatment on 7 May. Merit 0.5G was the only treatment that provided significant reduction of BB when compared to the untreated check (Table 1). On 25 Jun, four treatments provided significant differences in turf quality, while only two treatments provided significant differences in turf quality on 7 Jul (Table 2). A curative application of an insecticide plus fertilizer, provided that posttreatment irrigation is available, may mask BB larval feeding damage. No phytotoxicity was noted." |
