| Abstract/Contents: | "The objective of this study was to evaluate the efficacy of fungicides for the control of gray snow mold on a Kentucky bluegrass/annual bluegrass fairway. The trial was initiated on 30 Oct 08 on the Sun River Meadows golf course (4,160 ft elevation) located in Sun River, Oregon, 15 miles south of Bend. The size of the plots measured 6-ft long by 5-ft wide and included a 1-ft buffer between plots. Permanent snow covered the plots from 12 Dec 08 until 20 Mar 09. Fungicide treatments were applied with a CO2-powered twowheeled sprayer with a 5 ft boom using TeeJet 80015 nozzles spraying 2 gallons of spray solution per 1,000 square feet at 30 psi. Speed was calibrated with a KORG MA-30 metronome. Turf quality and disease ratings were taken on 26 Mar 09, 6 days after snow melt. Turf quality ratings were made on a 1 to 9 scale (9=best quality). Disease data (0 to 100% scale) was normalized using an arcsine transformation. Data was subjected to analysis of variance using a randomized complete block design with 4 replications. Differences between means were determined using Fisher's Protected LSD (Α=0.05). Permanent snow cover did not occur until 6 weeks after treatments were applied which may have contributed to the poor performance of some of the treatments, most notably Penstar FLO (PCNB) applied at 12 fl oz and Instrata applied at 9.3 fl oz. Disease pressure was moderate to severe. Generally, the treatments with Triton Flo provided higher turf quality than other treatments with statistically the same level of disease control. The only exceptions are the two combinations: Tartan + Daconil Ultrex mix, and Penstar FLO + 26GT + Daconil Ultrex which also provided good disease control and turf quality. Additionally, higher rates of Compass (applied as Interface or as itself) when mixed with Triton FLO provided better turf quality." |
