Abstract/Contents: | "The rough consisted of annual bluegrass (30%) and Kentucky bluegrass (70%). Treatment plots were 6 X 9 ft, arranged in a RCB design and replicated 3 times. Liquid formulations were applied in 0.5 gal of water with a hand held sprinkling can. Granular formulations were applied 1 May with a hand held shaker. At treatment time, the following environmental and soil conditions existed: air temp, 70 d F; soil temp at 1-inch depth, 57 d F; soil type, silt loam; soil pH, 5.0; % organic matter, 4.0; soil condition, moist; % soil moisture, 22.5; amt thatch, 0.5 inches; water pH, slightly acidic; % RH, 40; and clear sunny skies. A total of 5.1 inches of rain was recorded over the posttreatment period. Immediately after treatment, each replicate was individually watered-in with 0.25 inches of water. Posttreatment counts were made 28 days later (29 May). Four ft2 sod samples were randomly taken from each replicate and the total number of surviving Japanese beetle grubs were recorded for each ft2 sample. An average of 13 Japanese beetle grubs per ft2 was recorded 1 May before treatment. Posttreatment results showed that all formulations provided significant control. However, Triumph 1G provided the most significant control. No phytotoxicity was noted." |
