| Abstract/Contents: | "A standard treatment and two candidate RIFA quarantine treatments were applied 21-23 May 1991 to nonproduction field of common St. Augustine grass near Wadsworth, TX. Plots were 0.4 ha (210 X 210 ft) arranged in a CRD with 6 replicates per treatment. Granular formulations were applied witha Herd GT-77 granular applicator mounted on a John Deere AMT 600 all-terrain vehicle. Sprays were applied with a roller pump boom sprayer comprised of five KSS-3 spray tips spaced 0.9 m apart. The system was pressurized to 1.0-1.25 kg/cm2 and towed behind a Honda 300 all-terrain vehicle, provideing a delivery rate of 115.5 liter/ha. RIFA population assessments were made in 0.1 ha circular subplots in the center of each treatment plot immediately prior to, and at 4, 8, 12, 20, and 36 wk after application using a population indexing system described elsewhere (Lofgren and Williams; 1982. J. Econ. Entomol. 75: 798-803). Data were analyzed for treatment differences using ANOVA and the Tukey test. The RIFA population averaged 235 nests per ha prior to application. All treatments significantly reduced the population below that of the untreated check on all sample dates, except Dursban 10 G at 20 wk posttreatment. Residual activity of Suscon Green was superior to all other treatments. No phytotoxicity was observed in any treatment." |
