| Abstract/Contents: | "Two rates of Merit WP were compared for efficacy against the annual bluegrass weevil on golf course greens in Keene, NH. Plot size was 10 x 20 ft arranged in a RCB replicated 4 times. Treatments were applied 5 May and rated 28 Jun. Treatments were applied with a backpack sprayer in a volume of 1.4 gal water/1000ft2. After application, treatements were irrigated with 0.25 inches water. Treatments were rated by removing 3 (0.1 ft2) samples per plot and counting live larvae in the laboratory. Conditions at the time of treatment were: air temperature, 58.1 degrees F; soil temperature 1 in, 56 degrees F; thatch depth, 0.25 inch; soil pH, 5.9; soil texture, sandy loam; soil organic matter, 5.2%; soil moisture, 22%. All treatments significantly reduced populations compared to the check. There was no difference between Merit and the standard Dursban. No phytotoxicity was observed." |
