| Abstract/Contents: | "Pink snow mold caused by Microdochium nivale is a major disease of turfgrasses during the winter season in Wisconsin. One hundred sixty isolates of M. nivale, collected from golf courses throughout Wisconsin, were analyzed for their genetic diversity, pathogenicity, and virulence to bentgrasses. In growth chamber experiments, 86% of the isolates were pathogenic to both a creeping bentgrass 'Penncross' and a colonial bentgrass 'Tiger'. Virulence of eight different isolates of M. nivale from four genetically diverse groups estimated from RAPD marker-derived genetic distance, were evaluated on 80 day-old cultivars of bentgrasses (nine creeping, five colonial and three velvet) under controlled environmental conditions. The virulence and host resistance of M. nivale isolates among cultivars and species of bentgrass were statistically significant (P < 0.0001), however, no significant interaction between cultivars and isolates was detected. Of the three bentgrass species, creeping bentgrass was the most resistant to M. nivale isolates. Of the 17 cultivars, 'Pennlinks' creeping bentgrass was the most resistant, while 'Bardot' colonial bentgrass was the most susceptible to the pathogen. Increasing the inoculum concentrations (fresh mycelium weight/volume) of M. nivale significantly increase the amount of disease development in each bentgrass species. However, a slope of the dose response disease curve was steeper in virulent isolates than less virulent isolates. Comparison of field and in vitro evaluations of virulence and pathogenicity of M. nivale on bentgrasses will be discussed." |
