| Abstract/Contents: | "This study was undertaken to determine product effectiveness of experimental and standard formulations to preventively suppress a mixed adult population of bluegrass and hunting billbug. The turfgrass area consisted of annual bluegrass (20%) and Kentucky bluegrass (80%) and was maintained at Penn State's Valentine Turfgrass Research Center at University Park. Treatment plots were 6 ^D#x 4 ft, arranged in a RCB design and replicated four times with a 1 ft barrier around all replicates. Liquid formulations were applied by using a CO2 sprayer with four 8002VS TeeJet nozzles mounted on a 6 ft boom, operating at 28 psi, and applied in 363 ml of water/24 ft2 or delivering 4.0 gal/1000 ft2. Treatments were applied in early afternoon on 5 May to moist soil and thatch under partly cloudy skies. At that time, air temp was 73°F with RH = 28.4%. Soil temp at 1 and 2 inch depth was 56 and 51°F, respectively. Amount of thatch was 0.125-0.25 inch and water pH = 7.0. No irrigation was applied after treatments were completed. General soil conditions were as follows: soil textural class, silt loam; soil particle size analysis: sand, 16.2%; silt, 64.1%; clay, 19.7%; soil percent water content (percent by wt), 21.8; organic matter, 4.6%; CEC, 11.4; and soil pH, 6.1. Two 4 inch cup cutter sod samples were removed from each replicate on 6 Jul. The total no. of billbug larvae and pupae was counted and converted to ft2. Data was analyzed using Waller-Duncan k ratio (WD; P ≤ 0.05). The area selected for the experiment had been infested with a natural population of billbugs during the fall of 2004 and spring of 2005. Both bluegrass and hunting billbug species were present based on adult recovery from pitfall traps. DPXE2Y45 and Merit provided significant reduction of billbug larvae and pupae; however, DPXE2Y45 formulations, disregarding rate applied, provided 100% reduction of billbug larvae and pupae. Talstar F was not significantly different from the untreated checks. No phytotoxicity was noted." |
