| Abstract/Contents: | "This evaluation was conducted at Berkshire Hills Country Club in Pittsfield, MA on an annual bluegrass, creeping bentgrass, and Kentucky bluegrass 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 plots. 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 fungicide treatments were applied on 19 Nov 10. Fungicide treatments Agion Exp A, B, C and D were applied as split applications on 12 and 19 Nov 10. Snow mold severity (caused by T. incarnate and M. nivale) was visually assessed as percent snow mold symptoms per plot. Turfgrass quality was assessed on a 1 to 9 scale with 6 being acceptable. Both ratings were made on 28 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. The majority of snow mold damage was caused by gray snow mold (T. incarnate-90%) and to a lesser extent by M. nivale (10%). Most treatments provided significantly better control than the untreated, with the exception of 14 out of the 41 treatments. The tank-mixture of Torque + 26/36 + Spectro was the only treatment to provide complete control of all snow molds. Velista, which belongs to the succinate dehydrogenase (SDHI) fungicide class, provided good control for gray snow mold alone and in several combinations; however, most snow mold observed on plots treated with Velista was caused by M. nivale. Many treatments (26 of 42) provided acceptable turf quality as well as acceptable snow mold control. A slight degree of phytotoxicity was observed in plots treated with Turfcide 400, which was the only treatment to exhibit any phytotoxicity." |
