Abstract/Contents:"This evaluation was conducted at Manchester Country Club in Manchester, VT on a creeping bentgrass, annual bluegrass, and perennial ryegrass fairway maintained at 0.5-in. mowing height. Individual plots measured 3 ft x 6 ft (18 ft2), and were arranged in a randomized complete block design with three replications and a 1-ft buffer strip between each plot. Fungicides were applied based on labeled or suggested rates. Individual treatments were applied at a nozzle pressure of 40 psi using a CO2-pressurized boom sprayer equipped with two XR Teejet 8004 VS nozzles. All fungicides were agitated by hand and applied in the equivalent of 2 gallons of water per 1,000 ft2. All fungicides were applied on 18 Nov 10. Fungicide treatments Agion Exp A, B, C and D were applied as split applications on 11 and 18 Nov 10. Snow mold severity (caused by T. incarnata, T. ishikariensis and M. nivale) was visually assessed as percent snow mold symptoms per plot. Turfgrass quality was assessed using a 1 to 9 scale with 6 being acceptable. Both assessments were made on 31 Mar 11. Data were subjected to analysis of variance and means were separated using Fisher's protected least significant difference test. Snow cover persisted on the experimental plot for approximately 90 to 100 days and moderate disease severity was observed within untreated plots. Majority of the snow mold damage was caused by gray snow mold (T. incarnate-98%) and to a lesser extent by M. nivale (2%). Most treatments provided significantly better control than the untreated, with the exception of 5 out of the 41 treatments. Ten different treatments completely controlled all snow molds and most treatments (31 out of 41) provided good control of snow molds (< 5%). Acceptable turf quality (> 6) was observed among most treatments (30 out of 42). Turfcide 400 was the only treatment to provide good snow mold control without providing acceptable turf quality, which was due to slight phytotoxicity observed. This was the only treatment to exhibit any phytotoxicity. The new product Velista provide excellent gray snow mold control, however, the small amount of damage observed was caused by M. nivale."
