Abstract/Contents: | "Pink snow mold (Mirodochium patch) and gray snow mold (Typhula blight) are the most prevalent and destructive winter diseases on cool-season turfgrass in the northern USA. They are especially destructive in the Intermountain Northwest where deep snow cover may last four to five months. Pentachloronitrobenzene (PCNB, Quintozene) has been use [used] to manage these diseases in turf on golf courses for many years. When used alone, over time, pathogen resistance may develop, as well as other turf and environmental problems. This research sought to identify new chemistry and combinations of compounds that could be used in rotation with PCNB. Research was conducted on golf course bentgrass (Agrostis stolonifera L.)/Poa annua golf greens and nurseries during a three-year period (2000-2003). In locations with mild to moderate winters, many of the older chemistry fungicides used alone, or in combination with a compound with newer chemistry, gave good control. In locations with prolonged snow cover, combinations of two and possible [possibly] three fungicides are needed for adequate control. Numerically, but not statistically different from all other treatments, overall sites and years the treatment with the best control with good spring turfgrass quality was Medallion + Banner MAXX + Daconil Ultrex." |
