| Abstract/Contents: | "Dollar spot, caused by Sclerotinia homoeocarpa, is an important disease of most turfgrass species worldwide. S. homoeocarpa was described almost a century ago by F.T. Bennett, however the basic biology and epidemiology of the pathosystem is still unclear. Four isolates of S. homoeocarpa from Wisconsin and six isolates from Oklahoma were grown on native soil and USGA greens-grade sand. WI isolates were grown with and without creeping bentgrass (CRB) debris and incubated at temperatures ranging from 11 to 34C. OK isolates were grown with CRB debris only at temperatures of 15, 20, 25, 30, and 35C. Radial growth of mycelia was recorded at 24, 48, 72, and 96 hours past infestation. Growth for all isolates was most rapid between 20 and 30C. WI isolates grew best on native silt loam with CRB debris, while the effect of soil treatment was not significant for the OK isolates. Growth was limited and sporadic at temperatures below 15C. To assess aggressiveness, CRB plants were inoculated with 3 WI isolates and 6 OK isolates and placed in separate growth chambers set at 10, 14, 20, 25, 30 or 34C. Disease severity was visually assessed every 24 hours for four days. Disease developed in each temperature treatment, yet was most severe at 14 and 20C for all isolates. These data indicate a temperature window for dollar spot development, but also demonstrate that another environmental parameter such as relative humidity is likely more important for dollar spot development." |
