Abstract/Contents:"Snow molds are a major cause of damage to golf course fairways during the winter in the upper Midwest. Five varieties of both creeping bentgrass (Agrostis palustris) and colonial bentgrass (Agrostis capillaris), and six varieties of fine fescue (Festuca spp.), were evaluated for tolerance to snow mold fungi (Typhula incarnata, T. ishikariensis, T. phacorrhiza, and Microdochium nivale) found in Wisconsin. Three sets of field studies were repeated twice, each over a two year period, in southern, central, and northern Wisconsin (Verona, Stevens Point, and Land O'Lakes, respectively). Each location represented a unique snow mold complex. Plots were split to allow evaluation for both natural and artificial inoculum. The turfgrasses were also evaluated for resistance to all four pathogens in a controlled environment. Typhula incarnata was the most pathogenic, followed by T. incarnata and M. nivale. T. phacorriza [phacorrhiza] was not pathogenic under field conditions, and weakly pathogenic in a controlled environment. The fine fescues and colonial bentgrasses were more tolerant to the snow mold pathogens than creeping bentgrass. In field conditions the fine fescues were infested with Poa annua by the second year, while two varieties of colonial bentgrass significantly resisted P. annua invasion."
