| Abstract/Contents: | "Two studies were located side by side on a golf course fairway at Toledo, OH. Insecticides were applied 30 Aug to plots 12 ft (3.66 m) in length x the width allowed by the application equipment (3 or 4 ft wide) arranged in a RCB replicated 4 times. Granular insecticides were placed in two passes using a Cushman Ryan prototype subsurface applicator. The prototype cuts 11 slits into the turf on 2 inch (5.1 cm) centers and deposited granules 1/2 to 1 inches (ca 2 cm)deep. Liquid products were subsurface placed with one pass using a modified Rain Saver Jr liquid polymer injection machine at a 3.34 gal/1000 ft2 (1360 l/ha) volume. The machine cut 16 slits in the turf 2 inches (5.1 cm) apart placing the solution 1/2 to 3/4 inches (ca 2 cm)into the thatch-soil profile. Surface sprays were applied using a CO2 sprayer with Teejet 8015 nozzles at 55 psi (3.87 kg/cm2) pressure that delivered a volume of 3.32 gal/1000 ft2 (1352 liter/ha). Surface application of granules were made into two passes with a two foot Gandy drop spreader. All surface treatments were hand irrigated with 1/2 inch (13 mm) water immediately after each plot was treated. The site received 0.1 inch rainfall within 18 h after applications were made. Environmental conditions at the time of treatment were as follows: JB [Japanese beetle] larvae: ca. 194/m2, 10% 1st, 70% 2nd, 20% 3rd instars. Turf: level, dry, 3/4 inch (2 cm) height, mix of Kentucky bluegrass, annual bluegrass, and bentgrass. Thatch: dense, 1/2 inch (13 mm) moist. Soil: moist, 90 degrees F at 1 inch (2.5 cm) and 83 degrees F at 3 inches (7.6 cm). Weather: sunny, 91 degrees F, 3-7 mph (5-11 km/h). Water: pH, 4.9. Efficacy data taken 6 Oct (37 DAT) were based on the number of live JB larvae in six 7 inch x 7 inch (17.8 x 17.8 cm) square samples from each plot. No phytotoxicity was observed." |
