The study was located on a golf course fairway at Seville, Ohio. Insecticides were applied 1 Sep to plots 8 × 10 ft (2.4 × 3.1 m) arranged in a randomized complete block, replicated 4 times. Liquids were applied using a CO2 sprayer with Teejet XR8006VS nozzles at 35 psi (2.46 kg/cm2) pressure that delivered a volume of 1 gal/1000 ft2 (407 liter/ha). The experimental area was irrigated approximately V> in (6 mm) after all treatments were applied but before sprays had dried on the grass blades. Environmental conditions at time of treatment were as follows. JB: ca. 215/m2, 60% 2nd and 40% 3rd instars. Turf: slight slope <5° dew, 1 in (2.5 cm) height, 65% Bentgrass, 30% annual bluegrass, 5% other grasses. Thatch: dense, moist, 5/s in (1.6 cm) Soil: moist, 73°F at 1 in (2.5 cm) and 72°F at 3 in (7.6 cm). Weather: cloudy and light rain, 74°F, 0 mph. Water: pH 5.1. Efficacy data taken 5 Oct (35 DAT) were based on the number of live JB larvae in six 7 × 7 in (17.8 × 17.8 cm) square samples from each plot.
