Abstract/Contents: | "The only RIFA quarantine treatment labeled for use on grass sod is Dursban 50W-N applied at 8.0 lbs (AI)/acre. Treatments were applied to non-production sod in Hattiesburg, MS on May 21, 1997 under good conditions; air temperature was 75-85°F and soil temperature was 72-80°F. The site did not receive supplemental irrigation. Plots were 0.8 acre arranged in a CRD with three replicates per treatment. Granular formulations were applied with a Herd GT-77 granular applicator mounted on a farm tractor. Liquid treatments were applied with a shop-built roller pump boom sprayer equipped with 3 TKSS tips which provided a 10 ft. swath. The system was operated at 50 psi providing 37.5 gal of finished spray per acre. RIFA population assessments were made in 0.25 acre circular subplots in the center of each treatment plot immediately before treatment and at 6 wk intervals thereafter using a population indexing system (Lofgren and Williams, 1982, J. Econ. Entomol. 75: 798-803). Data were analyzed for treatment differences using ANOVA and means separated by LSD test (P=0.05). All rates of EXP 60818A significantly reduced RIFA populations below that of the corresponding untreated check, and were not significantly different from the Dursban treatment at any assessment interval. However, all rates of EXP 60818A maintained > 93% control of RIFA up to a year after treatment, whereas the Dursban treatment showed progressively lower efficacy rates 46-52 wks after treatment. No visible phtotoxicity was observed." |
