Abstract/Contents:"This study was undertaken to determine the product effectiveness of registered and experimental formulations to preventively control a mixed adult population of bluegrass and hunting billbugs. The predominant billbug species present was hunting billbug (82.6%). The turfgrass area consisted of Kentucky bluegrass (80%) and annual bluegrass (20%) and was maintained at Penn State's Valentine Turfgrass Research Center at University Park. Treatment plots were 7 Œ 4 ft, arranged in a RCB design and replicated four times with a 1 ft barrier between all replicates. Liquid formulations were applied by using a CO2 sprayer with four 8002VS TeeJet nozzles mounted on a 7 ft boom, operating at 32 psi, and applied in 424 ml of water/28 ft2 or delivering 4.0 gal/1000 ft2. The granular formulations were applied with a hand-held shaker and mixed with fine top dressing sand to facilitate product distribution. At treatment time one (23 Apr) the following soil and environmental conditions existed: air temp, 57°F; soil temp at l inch depth, 50°F; soil temp at 2 inch depth, 50°F; RH, 38%; amt of thatch, 0.75 inch; water pH, 7.0; application time, mid-morning; soil and thatch, moist; and clear skies. No post irrigation was applied after application. General soil conditions were as follows on 23 Apr: soil textural class, silt loam; soil particle size analysis: sand, 17.6%; silt, 60.4%; clay, 21.9%; soil percent water content (percent by wt), 22.0; organic matter, 4.3%; CEC, 14.0; and soil pH, 6.4. At treatment time two (5 May) the following soil and environmental conditions existed: air temp, 56°F; soil temp at l inch depth, 50^DGF; soil temp at 2 inch depth, 48°F; RH, 47%; amt of thatch, 0.75 inch; water pH, 7.0; application time, late-morning; soil and thatch, moist; and clear skies. General soil conditions were as follows on 5 May: soil textural class, silt loam; soil particle size analysis: sand, 18.4%; silt, 63.6%; clay, 18.0%; soil percent water content (percent by wt), 23.7; organic matter, 4.7%; CEC, 15.6; and soil pH, 6.2. No post irrigation was applied after application. At treatment time three (13 May) the following soil and environmental conditions existed: air temp, 67°F; soil temp at l inch depth, 60°F; soil temp at 2 inch depth, 56°F; RH, 37%; amt of thatch, 0.75 inch; water pH, 7.0; application time, mid-afternoon; soil and thatch, moist; and clear skies. No post irrigation was applied after application. General soil conditions were as follows on 13 May: soil textural class, silt loam; soil particle size analysis: sand, 17.3%; silt, 60.5 %; clay, 22.2%; soil percent water content (percent by wt), 22.6; organic matter, 4.7%; CEC, 14.5; and soil pH, 6.3. Two, 4 inch cup cutter sod samples were removed from each replicate on 7 Jul. The total no. of billbug larvae and pupae was counted and converted to ft2. Data were analyzed with ANOVA and the mean separation test used was LSD. The area selected for the experiment had been infested with a natural population of billbugs during the fall of 2007 and spring of 2008. Eight pitfall traps were positioned in the turfgrass. Hunting billbug was the predominant adult species recovered from April through early June pitfall trap samples. The highest pitfall adult count was recorded on 27 May from eight pitfall traps. The first adult was recovered on 29 Apr (166 GDD). Billbug adult populations were lower when compared to 2007 trap data which may be the result of an extremely wet spring and negative effects of beauveria sp. Nine treatments provided significant reduction of billbug life stages. No phytotoxicity was noted."
