| Abstract/Contents: | "Dollar spot, a disease caused by the fungus Sclerotinia homoeocarpa, is a widespread, important disease of most turfgrass species worldwide. Dollar spot on turf was described almost a century ago by F.T. Bennett. However, the basic biology and epidemiology of the pathosystem is still unclear. Two isolates of S. homoeocarpa were grown on native silt loam and Waupaca sand with and without creeping bentgrass (Agrostis stolonifera) debris and incubated at several temperatures (14, 20, and 26°C). Radial growth of mycelia was recorded at 24, 48, 72, and 96 hours to assess effect of soil temperature on survival and pathogenicity. S. homoeocarpa grows most rapidly at 26°C on native silt loam with bentgrass debris (36% faster than Waupaca sand with debris, 76% faster than bare native silt loam, and 86% faster than bare Waupaca sand). Growth is significantly slower at 14 on both soils. Growth on bare silt loam and sand is evident, but is extremely slow and variable. These data suggest that S. homoeocarpa is able to survive in the absence of plant debris on soil, and that higher temperatures (20-26°C) are conducive to growth and pathogenicity." |
