| Abstract/Contents: | "Two formulations of Merit were compared for efficacy against Japanese beetle grubs on a golf course fairway in Amherst, NH. Plots were 10 x 10 ft, replicated 4 times in a RCB design. Treatments were applied 26 Apr and rated 24 Sep. The granular formulation was applied with a homemade salt shaker. The wettable powder was applied in a watering can at a volume of 5 gal water/1000 ft2. After application, plots were irrigated with 0.5 inches of water. Plots were rated by counting the number of live grubs in a 3 ft2 sample. Conditions at the time of treatment were: air temperature, 53.3 degrees F; soil temperature, 2 inches, 50.8 degrees F; thatch depth, 0.5 inch; soil pH, 5.8; slope. 1%; soil texture, sandy loam, 53% sand, 43% silt, 4% clay; soil organic matter, 6.5%; soil moisture, 19.4%. Both formulations significantly reduced grub populations. No phytotoxicity was observed." |
