| Abstract/Contents: | "The turfgrass area consisted primarily of annual bluegrass (40%), Kentucky bluegrass (40%), and perennial ryegrass (20%). 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 (23 Aug) the following soil and environmental conditions existed: air temperature, 72°F; soil temperature at 1 inch depth, 72°F; soil temperature at 2 inch, 72°F; RH, 55%; amount of thatch, 0.125-0.5 inches; soil type, loam; soil particle size analysis: 41.6% sand, 32.6% silt, 22.2% clay; organic matter, 17.9%; soil moisture (oven baked), 34.2%; water pH, 6-7; soil pH, 6.2; and clear skies. Immediately after treatment the experimental area was irrigated with 0.275 inches of water. Posttreatment counts were completed on 27 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 18.4 grubs/ft² was recorded on 22 Aug prior to treatment. Eleven treatments provided significant control. No phytotoxicity was noted." |
