| 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 3 replications. Insecticide treatments were applied 2 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 of water. A total of 0.29 and 0.68 inches of rain fell respectively, during the 7 and 14 day post-treatment periods. Product efficacy was evaluated 9 and 16 Sep (7 and 14 DAT) by removing from each plot three turf-soil cores to a depth of 1 inch with a 4.25-inch cup cutter (0.3 ft2 total area per plot). Cores were returned to the laboratory and placed in Berlese funnels. Extracted chinch bugs were counted after 48 hr. Pretreatment counts indicated 10-15 chinch bugs (nymphs and adults) per square foot. Of the products under investigation, only the Sevin 80WSP treatment provided statistically significant reductions in chinch bug numbers. This occurred in part, because of a high degree of variability among plots which resulted in poor separation of the means. Numerically, however, both the Biosys nematode #25 and Beauvaria bassiana (AF4) treatments seemed to provide some measure of chinch bug reduction. No phytotoxicity was observed." |
