Abstract/Contents: | "The turfgrass area consisted primarily of annual bluegrass (30%), Kentucky bluegrass (40%), and perennial ryegrass (30%). Treatment plots were 9 x 6 ft, arranged in a RCB design, replicated 3 times. Granular formulations were applied with a hand-held shaker and mixed with a fine grade top-dressing sand to facilitate product distribution. At treatment time (21 Aug) the following soil and environmental conditions existed: air temperature, 73°; soil temperature at 1 inch depth, 84°F; soil temperature at 2 inch, 80°F; RH, 84%; amount of thatch, 0.25-0.75 inches; soil textural class, sandy loam; soil particle size analysis: 58.2% sand, 31.8% silt, 10.0% clay; organic matter, 4.9%; soil moisture (oven dry weight), 25.8%, water pH, 7.0; soil pH, 6.4; treatment time, early morning; and clear skies. Immediately after treatment the experimental area was irrigated with 0.25 inches of water. Posttreatment counts were completed on 26 Sep. Three ft² sod samples were taken from each replicate, and the total number of viable Japanese beetle grubs/ft² was recorded. An average of 25.3 grubs/ft² was recorded on 21 Aug prior to treatment. No treatments provided significant control. Phytotoxicity was noted 10 DAT with select experimental formulations." |
