| Abstract/Contents: | "This test was conducted on mature, low-maintenance Kentucky bluegrass turf at the University of Kentucky Spindletop Farm, near Lexington. The turf was on a Maury silt loam soil (Ph = 6.4) with negligible thatch. Plots (6 X 6 ft) were arranged in a RCB design with 4 replicates. Treatments were applied once a month in Jun, Jul, and Aug. Granular formulations were preweighed, mixed with dry sand, and applied by gloved hand. Liquid applications were applied at 50 gpa using a low volume, Co² sprayer equipped with 4 Spraying System 8004 Tee Jet nozzles that delivered 2109 g pressure per cm₂. The whole site received 1/2 inch irrigation as soon as the last treatment was applied. Conditions during the time of treatment were 85, 86 and 89°F, respectively, with winds < 10 mph for all apllications. The site received natural rainfall between treatments as well as post-treatment irrigation after all applications. Plots were sampled on 17 Sep by cutting a 3 X 1.5 foot strip, about 3 inches deep, from the center of each plot with a motorized sod cutter. Sod was rolled back, broken apart, and examined for grubs which were counted and identified. At time of sampling, densities in control plots averaged about 8 per sample (1.8 per ft₂). The data presented is based on 3 replicates instead of 4 because in 1 replicate no grubs were present in any of the treatments. The grub population density in all the treatments was significantly lower than that in the untreated check. But, different timings of treatment with the two insecticides did not result in significant differences in the grub numbers. There was no evidence of phototoxicity from any treatment." |
