| Abstract/Contents: | "Insecticides were evaluated for control of mealybugs on a buffalograss lawn at the University of Nebraska Agricultural Research and Development Center near Mead, Nebraska. The turf (100% buffalograss) was maintained at a mowing height of 3.5 inches but was mowed to a height of 2 inches prior to insecticide applications. Thatch accujmulation (finger compressed) in the plot area was 0.25 inches. Field conditions at the study site were: soil type, silty clay loam; soil organic matter, 3-5%; soil pH, 6.7; water pH, 7.0. Environmental conditions at the time of treatment were as follows: soil moisture 13%; air temperature 83°F; soil temperature 70°F; relative humidity 53%; wind direction and velocity 177° at 10 mph. Plots were 4 x 4 ft and the experimental design was a RCB with 3 replications. Insecticide treatments were applied on 28 Aug, 1995. Granular treatments were applied by using a precalibrated 24H12 Gandy spreader. Liquid insecticides were applied using a CO₂ sprayer with an LF-4 nozzle at 30 psi and delivering 4 gal finished spray/1000ft². Following applications, plots were irrigated with 0.125 inches of water. No rain fell during the post treatment period. Treatments were evaluated 37 DAT (4 Oct) by removing from each plot three, 4.25 inch diam turf-soil cores (0.3 ft² total area) to a depth of 1 inch. Cores were placed in Berlese funnels and extracted mealybugs were counted after 48 hr. Pre-treatment estimate of insect activity was 75 mealybugs per 1.0 ft². All products under investigation provided statistically significant reductions in mealybug numbers when compared to the untreated control. Eighteen of the 25 product/rate combinations tested provided greater than 80% control. Although not statistically significant, EXP60655A, EXP60720A, PL95-118, and Saga produced numerical rate responses. No phytotoxicity was observed." |
