| Abstract/Contents: | "Tests were conducted in 6.6 x 6.6 ft turf plots planted on sandy loam soil Sep 1997 and randomized with either Kentucky bluegrass, hard fescues, or turf type tall fescue at the Valley Laboratory, Windsor, CT. Two soil types divided the research field: a loamy sand had 78% sand, 17% silt, and 5% clay for the mineral component and 3.4% organic matter. The sandy loam portion consisted of 73% sand, 20% silt, and 7% clay, with 4.6% organic matter. There were 4 replicates for each treatment within each treatment within each species of turfgrass in a factorial RCB design. Thatch varied from 0-0.75-inch depth. Insecticides were applied with a CO₂ -pressurized research sprayer and a TeeJet 8002 nozzle calibrated to give 40 gpa at 25 psi. Each application was followed by 0.5 inch of irrigation. The field was sampled 14 Oct for treatments applied 24 Aug, and 17-24 Sep for all other treatments. A 1 x 3.3 ft turf strip was lifted with a sod cutter and larvae counted to a 6-inch depth. Numbers of grubs were log-transformed, subjected to ANOVA, and their treatment means separated with the Student-Newman-Keuls test. June application of Merit was more effective against all species than the August timing. Thiamethoxam (CGA-293343) was most effective against JB and OB, and performed best to control EC when applied in June. Mach 2 required a 2 lb (AI)/Ac total application rate in June and/or July to significantly control both oriental beetles and European chafers." |
