| Abstract/Contents: | "The study was conducted on a buffalograss lawn in Lincoln, NE. The turf was maintained at a mowing height of 3.5 inches and thatch accumulation in the plot area was 0.25 inches. Field conditions at the time of application were: soil type, silty clay loam; soil organic matter, 3-5%; soil pH, 6-7; water pH, 7.0; soil moisture, near field capacity. Plots were 4 x 4 ft and the experimental design was a RCB with 4 replications. Insecticide treatments were applied 3 Sep. Prior to application, the plot area was mowed to 1.5 inches. Treatments were applied with a CO2 sprayer using a LF-4 tip at 24 psi and delivering 5 gal finished spray/1000 ft2. Immediately following application, plots were syringed with 0.25 inches water. Product efficacy was evaluated 8 Sep (5 DAT) by removing from each plot three turf-soil cores to a depth of 1 inch with a 4.25-inch diam cup cutter (0.3 ft2 total area per plot). Cores were returned to the laboratory and placed in Berlese funnels. After 48 hr extracted chinch bugs were counted. Pretreatment counts indicated 10-15 chinch bugs (nymphs and adults) per square foot. All rates of diazinon and the 6.0 lb rate of Sevimol 4 when combined with Safer Insecticidal Concentrate resulted in 100% chinch bug control. The insecticidal soap alone provided only 33% chinch bug reduction. No phytotoxicity was observed." |
