| Abstract/Contents: | "This evaluation was established to acquire data on spring white grub supression and residual control on a turfgrass area located at Penn State's Valentine Turfgrass Research Center at University Park. The turfgrass area consisted of perennial ryegrass (100%). Treatment plots were 9 x 6 ft, arranged in a RCB design and replicated three times. Liquid formulations were applied by using a hand held sprinkling can and 4 gal water. Granular formulations were applied with a hand-held shaker and mixed with fine top dressing sand to facilitate proper distribution. At treatment time (7 May), the following soil and environmental conditions existed: air temperature, 56°F; soil temperature at 1-inch depth, 60°F; soil temperature at 2-inch depth, 58°F; RH, 95%; amount of thatch, 0.0625-0.125 inch; soil textural class, silt loam; soil particle size analysis: 15.1% sand, 59.2% silt, 25.6% clay; organic matter, 3.1%; soil water content (percent by wt), 20.4; water pH, 7.0; soil pH. 5.8; treatments were applied in late-morning: 1.7 inch of rainfall was recorded from 7 May through 12 May; and sunny skies. Select treatments were irrigated with 0.125 inch of water immediately after treatment. Post-treatment counts were completed on 20 May and 16 Sep. Three sod samples, 1 ft² each, were randomly taken from each replicate, and the total number of living and dead white grubs/ft² was recorded. An average of 7.8 grubs/ft was recorded on 24 Apr. All treatments provided significant reduction or death of JB grubs 13 DAT while only seven treatments provided significant control by 16 Sep. The experimental formulations of halofenozide applied at three rates provided significant extended control of JB grubs. No phytotoxicity was noted." |
