| Abstract/Contents: | "This experiment was conducted on an old established commercial turfgrass area in Somerset, PA, to determine the effectiveness of treatments against a natural HCB population. The turfgrass area consisted primarily of fine leafed fescue. Treatment plots were 5 x 6 ft arranged in a RCB design and replicated three times. Granular formulations were applied with a hand held shaker with top dressing sand used to provide even distribution of product. At treatment time (2 Aug), the following soil and environmental conditions existed: air temp, 65°F; soil temp at 1 inch depth, 69°F; soil temp at 2 inch depth, 66°F; RH, 78%; amt of thatch, 0.125 inch; soil textural class, silt loam; soil particle size analysis: 37.6% sand, 50.9% silt, 11.6% clay; percent water content (percent by wt), 15.3%; organic matter, 7.7%; water pH, 7.0; soil pH, 6.0; application time, early morning; clear skies. Each replicate was irrigated with 0.055 inch of water immediately after treatment. HCB was sampled by driving a 6-inch diam stainless steel cylinder into the turf, filling it with water, and counting the number of HCB nymphs and adults floating to the surface during a 10 min period on two sampling dates, respectively, 12 Aug and 23 Aug. Two floatation samples were taken randomly from each replicate, and the total number of HCB from each sample was recorded and converted to a ft² count. Each replicate was evaluated for turf quality by utilizing a color rating of 1-9 where 1 = off color and 9 = dark green. The severe drought encountered in 1999 significantly impacted color ratings because of soil moisture deficits. Before the treatment, an avg of 64.6 HCB nymphs and adults/ft² were present. All treatments provided significant reduction on 12 Aug, while only two treatments provided significant control on 23 Aug (Table 1). Select checks on 23 Aug had minimal turf remaining which resulted in reduction of HCB life stages since no suitable food source was available. No significant differences in turf quality were observed on either sampling date (Table 2). The latter maybe attributed to lack of rainfall during the severe drought. No phytotoxicity was noted." |
