Abstract/Contents: | "The large plot study was conducted at the Amherst Country Club, Amherst, NH. Plot size was 20 x 80 ft, replicated 4 times. Treatments were applied in 1 gal water/1000 ft² with a Chem Pro sprayer using MC5 nozzles. Each plot was sprayed for a total volume of 2 gal/1000 ft². The first treatments were applied in the evening on 19 Aug to predominantly 2ⁿd instar larvae and watered in. The second half of the split application of Vector WG was applied on 9 Sep (21 days later). Plots were irrigated as necessary 2-3 times per week with 0.2 inch water to keep soil moist. Three 1 ft² samples were removed from each plot and the number of live larvae counted. Conditions at the time of treatment on 19 Aug were: air temperature, 68.3°F; wind, < 3 mph; sky, clear; soil temperature 2 inch, 69.3°F; thatch depth, 0.5 inch soil pH, 6.5; soil texture, loam, 38% sand, 45% silt, 17% clay; soil organic matter, 5.2%; soil moisture, 23.4%; post treatment precipitation, 0.3 inch soils were moist due to recent rain. Conditions at the time of treatment on 9 Sep were: air temperature, 72.3°F; wind, 0 mph; sky, clear; soil temperature 2 inch, 63.5°F; soil moisture, 25.6%; post treatment precipitation, 0.3 inch soils were moist due to recent rain. Plots were rated on 7 Oct (42 days after initial treatment). Proxol provided excellent control. Split applications of half rates of Vector did not provide any better control than the full rate applied once. No phytotoxicity was observed." |
