| Abstract/Contents: | "The experiment was conducted on a buffalograss lawn in Lincoln, NE. Insecticides were applied on 6 Sep to 5 X 5 ft plots arranged in a randomized complete block design and replicated 4 times. The predominant grass species was buffalograss (98%) which was maintained at a mowing height of 5.0 inches. Conditions at the time of appplication were as follows: air temperature, 78oF; soil temperature (4-inch depth), 72oF; soil type, silty clay loam; soil moisture was well below field capacity. Insecticides were applied with a CO2 sprayer using a LF-4 nozzle at 2 psi and delivering 4 or 10 gal finished spray/1000 ft2. A total of 4.79 inches of rainfall occurred during the post-treatment period. No irrigated water was applied. Product efficacy was evaluated 5 DAT (11 Sep) by cutting from each plot 4 randomly selected sections of turf to a depth of 2 inches with a 4-inch diameter cup cutter (0.35 ft2 total area per plot). Turf sections were returned to the laboratory and placed in Berlese funnels. Extracted chinch bugs were counted after 48 hr. Pretreatment counts indicated an average of 32 chinch bug nymphs and adults/0.35 ft2 in the test area. At 5 DAT, Talstar 10 WP (4 and 10 gal finished spray/1000ft2) and Dragnet FT (10 gal finished spray/1000ft2) provided greater than 90% reduction in chinch bug numbers. Heavy rainfall (4.79 inches) during the post-treatment period may have influenced the results of this study. No phytotoxicity was observed." |
