| Abstract/Contents: | "Four insecticides and one species of entomogenous nematode were applied to a fairway at Drumlins Country Club, Syracuse, N.Y., on 17 Aug for control of a mixed population of Japanese beetle and European chafer grubs. The fairway consisted of Kentucky bluegrass (40%), annual bluegrass (45%), bentgrass (10%), and broadleaf weeds (5%). 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 (17 Aug) the following environmental conditions existed: air temperature, 93F; soil temperature, 98F (1 inch), 96F (3 inches); soil pH 7.0; water pH 7.6; organic matter, 5.0%; soil moisture, 8.8%; soil texture, coarse sand, 15.6%, medium sand 30.7%, fine sand, 28.8%, very fine sand, 15.1% and silt and clay, 8.8%; thatch, <0.25 inches. The nematodes, Heterorhabditis sp. (strain HP 88), were applied at a rate of 5 billion/acre in 11.4 liters of water to the center 4 sq ft of each plot. Following treatment, the plots received 0.5 inch of water through the course's irrigation system. Posttreatment counts were taken on 28-29 Sep by cutting a 1- X 10-ft strip (2.25 inches deep) lengthwise through the middle of each plot with a mechanical sod cutter and examining the sod and underlying soil for grubs. A 3-sq-ft 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 Japanese beetle grubs and European chafer grubs were predominantly third instars. All insecticides significantly reduced the density of the white grub complex at this site. The area treated with nematodes was not significantly different from the untreated check. No phytotoxicity was seen in any of the plots." |
