| Abstract/Contents: | "This test was conducted on a 2-yr-old stand of hybrid Bermuda grass (Tifway 419) turf with negligible thatch at the Gulfport High School Soccer facility, Gulfport, MS. The objective of this study was to determine the relative efficacy of various rates of Provaunt compared to Talstar for control of armyworm. During the two wk study, the turf was irrigated every other day with about 0.3 inches, and mowed about two times per week at 0.75 inch cutting height. Plots, 12 ^D#x 12 ft, were arranged in a RCB design with four replicates. Treatments were applied in the afternoon on 18 Aug using a CO2-powered boom sprayer. Treatments for each plot were mixed with water in a 2l bottle so that the final solution was delivered to the turf at 2 gal/1000 ft2. Irrigation was withheld from the site for 12 h post-treatment. Plots were sampled at 2 DAT, 7 DAT and 14 DAT using a 3.3 Œ 3.3 ft (1 m ^D#x 1 m) sampling frame. A soap disclosing solution (30 ml of Ultra Lemon Joy dishwashing detergent in 2 gal of water) was applied to each frame and watched for larvae to surface for 10 min. Larvae were collected into labeled cups, placed into a cooler, and returned to the lab for counting. Data within each sample were analyzed using a general ANOVA followed by Fisher's LSD (P ≤ 0.05). Untreated check plots yielded an avg of 32 larvae over the 14 day experiment. On all sample dates, numbers of larvae recovered from treated plots were significantly less than those recovered from the untreated checks. There were no differences in control between any of the rates of Provaunt 14.5%SC. Likewise, all rates of Provaunt 14.5% performed as well as the standard Talstar F. Overall, less than one larva was recovered from plots treated with either Talstar F or the highest rate of Provaunt 14.5%SC in 14 days. There was no observed phytotoxicity resulting from any treatment." |
