Abstract/Contents: | "Several turf insecticides were tested for efficacy against Japanese beetle grubs on a golf course rough in Bolton, Mass., on 4 May. The test site consisted of annual bluegrass (25%), Kentucky bluegrass (40%), and perennial ryegrass (35%). Treatment plots were 8 X 8 ft, arranged in a randomized complete block design and replicated 5 times. Liquid applications were made with watering cans using 3 qt water/plot (ca. 4 gal/1,000 ft2). Granular applications were made using glass jars with perforated lids. At treatment time the following environmental conditions existed: air temperature, 62oF; soil temperature at two inch depth, 52%; amount of thatch, 0.6-1.0 inch; water pH 6.7; soil pH, 5.3; plots received ca. 4 inch deep were taken from each replicate, and the total number of Japanese beetle grubs/ft2 was recorded. All materials reduced population significantly relative to the untreated control, and all provided "acceptable" (>80%) levels of control. No phytotoxicity was observed at any time during the test." |
