| Abstract/Contents: | "Fungicides were evaluated on an established stand of Meyer zoysiagrass at the Manhattan Country Club, Manhattan KS. The turf was mowed to a height of 0.5-in. and fertilized with 3 lb N/1,000 ft2 during the season. Treatments were applied twice at 4-wk intervals beginning 18 or 19 Sep 06 except Heritage (TL 0.8 MEC) which was applied once on four staggered dates. Fungicides were applied with a CO2-powered boom sprayer with XR Tee Jet 8003VS nozzles at 30 psi in water equivalent to 2.0 gal/1000 ft2. Plots were 5 ft X 8 ft and arranged in a randomized complete block design with four replications. Plots were rated periodically through Oct 06 until turf became dormant and again starting at green-up in Apr and May 07 by visually estimating the percentage of infected area per plot. Large patch symptoms developed quickly and unexpectedly during 16-17 Sep 06, immediately prior to the first fungicide applications. Disease severity increased over the next month and on 18 Oct only Tartan II (both rates), TBZ + TFS at 2.0 oz, and Nativo had significantly lower disease severity compared to the untreated control, though Tartan II at 1.0 oz started with a lower disease pressure. In the spring symptoms first developed in late April when the turf became active. On 14 and 21 May there were no significant differences among treatments. On 30 May all treatments except Tartan II at the 2.0 oz rate and the late application of Heritage had significantly lower disease severity than the control. There were no significant differences among the different Heritage timing treatments on any rating dates, but the early treatment consistently led to the numerically lowest disease severity. All fungicides suppressed disease severity compared to the levels that were observed in the fall. No phytotoxic effects were observed, and there were no differences in green-up in the spring." |
