| Abstract/Contents: | "This study was undertaken to determine product effectiveness when applied preventively in mid-Jun to control a predominant Japanese beetle (JB) white grub population on turfgrass maintained at the Valentine Turfgrass Research Center. The turfgrass area consisted of perennial ryegrass (100%). Treatment plots were 6 Œ 8 ft, arranged in a RCB design and replicated three times with a 1 ft barrier around all replicates. Granular formulations were applied with a hand-held shaker and mixed with fine top dressing sand to facilitate product distribution. Liquid formulations were applied by using a CO2 sprayer with four 8002VS TeeJet nozzles mounted on a 6 ft boom, operating at 32 psi, and applied in 363 ml of water/48 ft2 or delivering 2.0 gal/1000 ft2. At treatment time (10 Jun) the following soil and environmental conditions existed: air temp, 74°F; soil temp at l inch depth, 70°F; soil temp at 2 inch depth, 68°F; RH, 79%; amt of thatch, 0.75 inch; water pH, 7.0; application time, early-morning; soil, moist; thatch, moist; and clear skies. General soil conditions were as follows: soil textural class, silt loam; soil particle size analysis: sand, 16.1%; silt, 70.7%; clay, 13.2%; soil percent water content (percent by wt), 25.2; organic matter, 4.7%; CEC, 12.4; and soil pH, 6.3. Immediately after treatment the area received 0.1 inch of irrigation. Throughout the summer and early fall the area was irrigated on an as needed basis. Three, one ft2 soil samples were removed from each replicate on 6 Oct and the total no. of JB and NMC grubs was recorded and converted to a ft2 count. Data were analyzed with ANOVA and the mean separation test used was WD. The area selected for the experiment had been infested with a natural population of JB and NMC grubs during the spring of 2008 with an avg of 21.6/ft2 white grubs present in late Apr. JB was the predominant species present with minimal no. of NMC recorded. Fall 2008 grub populations may have been suppressed by the extremely dry summer weather. Adult NMC's were monitored in 2008 with a black light trap maintained at the Valentine Turfgrass Research Center, while JB populations were monitored with floral/sex pheromone traps. Adult JB and NMC populations were late this year. All treatments provided significant suppression of JB grubs, while NMC populations no. were insignificant. No phytotoxicity was noted." |
