| Abstract/Contents: | "Four insecticides and 1 species of entomogenous nematode were applied to a rough at Fresh Meadow Country Club, Great Neck, Long Island, N.Y., on 12 Aug for control of Oriental beetle grubs. The fairway consisted of Kentucky bluegrass (35%), annual bluegrass (45%), and broadleaf weeds (20%). The experimental design was a randomized complete block with 4 replications. Individual plots were 10 X 10 ft. Granular materials were applied with a precalibrated Gandy 2.5 spreader. At treatment time (12 Aug) the following environmental conditions existed: air temperature, 84F; soil temperature, 68F (1 inch), 67F (3 inches); soil pH 5.1; water pH 6.65; soil moisture, 23.8%; soil texture, 11.1% coarse sand, 50.9% medium sand, 23.3% fine sand, 8.1% very fine sand, and 5.7% silt and clay; thatch, minimal. Following treatment, the plots received 0.5 inches of irrigation by sprinkler. The nematodes, Heterorhabditis sp. (strain HP 88), were applied on 20 Aug at a rate of 5 billion/acre in 5 liters of water through a sprinkling can to the center 4 sq ft of each plot. The nematode application site was immediately watered in by hand for a total of 11.4 liters. Posttreatment counts were taken on 21 Sep by cutting a 1- X 3-ft strip lengthwise through the middle of each plot by hand and examining the sod and underlying soil for grubs. A 3-sq-ft square sample of sod was examined in each plot, and the surviving grubs were counted. Grub species identifications were made in the field. At this time Oriental beetle grubs were 80% third instars and 20% second instars. All insecticides significantly reduced the number of oriental beetle grubs at this site; Dylox was most effective. The area treated with nematodes did not result in a significant reduction in grub density. No phytotoxicity was seen in any of the plots." |
