| Abstract/Contents: | "Two formulations of Bacillus thuringiensis japonesis Buibui were evaluated for control of GJB grubs on a bermudagrass fairway at the Quail Ridge Golf and Country Club in Sanford. Turfgrass on the site is mowed at 0.88 inch and has 0.25 inch of thatch. The sandy loam soil had a pH of 5.6 and 0.51% humic matter. Plots 10 ft x 10 ft were established in an area with a history of GJB infestation and treatments (replicated 4 times) were randomly assigned to the plots. Insecticides were applied on 14 Aug under sunny skies (95Ā°F) to a population of primarily 1^D]st and 2āæd instar grubs. The spray formulations were applied using a COā-powered backpack sprayer with 8003 nozzles delivering approximately 30 gpa and operating at 40 psi. The area received 0.5 inch of irrigation the night before treatment and 0.25 inch of irrigation following treatment. All plots were oversprayed on 5 Sep with a 4.8 lb AI/acre rate of Sevin 80 WPS and were evaluated on 6 Sep (23 DAT) by counting all the dead grubs on the surface within two randomly placed one MĀ² frames in each plot. THe dead grubs from the Sevin overspray are assumned to have survived the initial "test" treatments. The average number of grubs counted (per mĀ²) in each plot are reported in the table. All data were transformed ā(x + 0.5) prior to ANOVA and DNMRT. Evaluation of the plots at 23 DAT reveal significantly fewer grubs counted in all the B. t. treatments as compared to the untreated plots. The MYX951 (both 3.1 and 9.3 gal/acre rate) were less effective than all other B. t. treatments." |
