| Abstract/Contents: | "Insecticides were evaluated for control of Southern masked chafers (SMC) on a Kentucky bluegrass research area at the University of Nebraska Agricultural Research and Development Center near Mead, NE. The turf (100% Kentucky bluegrass) was maintained at a height of 2.5 inches. Thatch accumulation (finger compressed) in the plot area was 0.5 inches. Field conditions at the site were: soil type, silty clay loam; soil organic matter, 3-5%; soil pH, 6.2-6.6; water pH, 7.0. Environmental conditions at the time of treatment were as follows: soil moisture 18 %, 18%, and 15%; air temperature 68°F, 76° F, and 73° F; soil temperature 63° F, 74° F, and 70°F F; relative humidity 79%, 73%, and 64%; wind velocity 6 mph, 6 mph, and 4 mph. Plots were 5 ^D#x 5 ft and the experimental design was a RCB with four replications. Insecticides were applied on 2 Jun, 29 Jun and 15 Aug 2005. Granule insecticides were applied using a hand shaker. Post-treatment irrigation was 0.25 inches. A total of 8.8 inches of rain accumulated during the post-treatment period. Treatments were evaluated 110 days after the first treatment (DAT) (20 Sep) by removing from each plot, three 8-inch-diameter turf-soil cores (1.05 ft2 total area) to a depth of 3 inches and counting the number of surviving grubs. Data were subjected to ANOVA and means were separated using LSD (P ≤ 0.05). All treatments at all application timings provided statistically significant reductions in southern masked chafer numbers when compared to the untreated control. We did not encounter any application problems with any of the formulations tested. No phytotoxicity was observed." |
