| Abstract/Contents: | "An experimental compound under development by DuPont was applied to golf course rough turf (maintained at 2 to 3.5 inches) on 14 Jul and sampled 14 Sep to determine the efficacy of the compound against Oriental beetle (OB) larvae. The test was conducted at Hickory Ridge Country Club, Amherst, MA. The conditions at the time of application were as follows: air temp, 77Ā° F; soil temp, 72Ā° F; water pH, 6.2; soil pH 5.1, buffered pH 6.0; CEC 15.2 Meq/100g; low overcast and calm. Treatment plots were 8 ^D#x 8 ft, replicated five times, and arranged in a CRB design. All sprayable formulations were applied with a watering can (3 qt water per plot). All granular formulations were applied using a jar with a perforated lid. Plots were irrigated with 0.2 inch of water within 1 h after application. Product efficacy was evaluated on 14 Sep by inspecting (on site) five 4.25-in-diameter cores from near the center of each plot. Each core was recorded separately, and all counts were included in statistical analyses (Fisher's Protected LSD, P ā¤ 0.05). The grub population in the untreated plots was well above the commonly accepted threshold population (10 to 15 larvae per sq ft). All treatments reduced insect populations significantly, including Merit 75WP and Merit 0.5G, which were included as industry standards. Two of the granular formulations had significantly higher OB grub populations than most of the sprayable formulations and both Merit formulations, and failed to reduce populations below threshold levels. The OB is much less vulnerable to many traditional insecticides than other grub species, and the same may be true for this compound." |
