Abstract/Contents:"The rough consisted primarily of annual bluegrass (20%), Kentucky bluegrass (20%), perennial ryegrass (20%) and 40% weeds. Treatment plots were 9 X 6 ft, arranged in a randomized complete block design and replicated 3 times. W and SP formulations were applied by using a CO2 sprayer with four 8004VS Tee Jet nozzles mounted on a 6 ft boom, operating at 28 psi at a spray rate of 5 gal/1000 ft2. At treatment time (7 Sep) the following soil and environmental conditions existed: air temperature, 78oF.; soil temperature at 1 inch depth, 72oF.; RH, 60%; amount of thatch, 0.125 inches; soil type, silt loam; soil particle size analysis: 40.0% sand, 50.4% silt, 9.6% sand; soil moisture, 13.1%; organic matter, 2.7%; water pH, 7.0; soil pH, 5.8%; 4.3 inches of rainfall was recorded over the posttreatment period. Immediately after treatment the experimental area was irrigated with 0.25 inches of water. Posttreatment counts were made 25 d later (2 Oct). Three ft2 sod samples were reandomly taken from each replicate, and the total number of Northern masked chafer grubs/ft2 was recorded. An average of 12.5 grubs/ft2 was recorded on 7 Sep. All treatments provided significant control. No phytotoxicity was noted."
