Abstract/Contents: | "Four insecticide formulations 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 soil was classified as a sandy loam with 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. All insecticides were applied 31 Aug using a CO₂-powered backpack sprayer with 8003 nozzle delivering approximately 30 gpa and operating at 40 psi. The test received 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 (6 DAT) by counting all the dead grubs on the surface with two m² frames randomly placed in each plot. These dead grubs from the Sevin overspray are assumed to have survived the initial "test" treatment. The average number of grubs counted (per sq m²) in each plot are reported in the table. All data were transformed √(x + 0.5) prior to ANOVA and DNMRT. Evaluation of the plots at 6 DAT reveal that only the Merit 75WP treatment had significantly fewer GJB beetle grubs than the untreated control plots; however, there was no significant difference between the number of grubs counted in this treatment and the FCR 4545 10 WP treatment." |
