Abstract/Contents:"Insecticides were evaluated for control of sod webworm larvae on a Kentucky bluegrass lawn at the Gering Cemetery, in Scotts Bluff County, Nebraska. The turf (80% Kentucky bluegrass, 20% perennial rye and tall fescue) was maintained at a mowing height of 2.5 inches. Thatch accumulation (finger compressed) in the plot area was 0.25 inches. Field conditions at the study site were: soil type, silt loam; soil organic matter, 1%; soil pH, 8.0. Weather conditions at the time of treatment were as follows: soil moisture 16%; air temperature 56°F; soil temperature 62°F; relative humidity 74%; wind direction and velocity 136° at 10 mph. Plots were 10 x 10 ft and the experimental design was a RCB with 4 replications. Treatments were applied on 11 May 1995. Liquid insecticides were applied using a CO₂ sprayer with an LF-4 nozzle at 30 psi and delivering 3 gal finished spray/1000 ft². Following applications, plots were irrigated with 0.125 inches of water. A total of 0.52 inches of rain fell during the post treatment period. Treatments were evaluated 4 and 7 DAT (15 and 18 May) by mixing 0.5 oz of Lemon Dawn© per gal of water and applying one gal of the dilution to each of two 6 ft sampling areas per plot (12.0 ft² total area). Larvae that moved to the grass surface were collected and counted after twenty minutes. At 4 DAT Dursban Turf at the 1.0 rate, Talstar F at the 0.0125 raate, and Bifenthrin 1 EC at the 0.0031 rate provided statistically significant reductions in sod webworm numbers when compared to the untreated control. By 7 DAT all formulations had provided statistically significant reductions in numbers and attained greater than 65% control. No phytotoxicity was observed."
