| Abstract/Contents: | "This test was conducted in turf-type tall fescue 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 (4 X 6 ft; 2 ft untreated borders) were arranged in a RCB, with 4 replications. The turf was treated on 27 Jul, during flight of JB. The soil population consisted mostly of eggs, with some 1st instars. Granular formulations were preweighed, mixed with dry sand, and applied by gloved hand. Liquid applications were applied at 50 gal/acre using a low volume, CO₂ sprayer equipped with 4 Spraying System 8004 Tee Jet nozzles that delivered 2109 g pressure per cm². Each plot was syringed with about 1/8 inch of water within 5 min after application, and the whole site received 3/4 inch irrigation as soon as the last treatment was applied. Conditions during application were 88°F with winds < 10 mph. There was 0.23 inch of rainfal on 26 Jul, the day before the test. There was no additional rain until 5 Aug, when 1.78 inch fell. The curative applicaion of Dylox 6.2G was made on 17 Aug, with 3/4 inch of irrigation immediately after treatment. All plots were sampled on 16 Sep. A motorized sod cutter was used to cut a 3 X 1.5 ft strip, about 3 inches deep, from the center of each plot. The sod was rolled back, broken apart, and examined for grubs, which were counted and identified. Grub densities in control plots averaged about 24 per strip (5.3/ft²) at the time of sampling. Most (82%) grubs were 3rd instar JB, with smaller numbers of SMC and MB. A relatively light beetle flight in 1995, together with very dry summer conditions contributed to generally low grub densities throughout Kentucky. Merit 1.67 SL at the low and high rates, and Merit 75WP at the high rate gave good residual control of grubs. The curative application of Dylox also was relatively effective. There was no evidence of phytotoxicity from and treatment." |
