| Abstract/Contents: | "Dollar spot, caused by Sclerotinia homoeocarpa, is the most prevalent and economically important turfgrass disease in North America. Increasing levels of fungicide resistance, coupled with tightening environmental scrutiny of existing fungicides, has left fewer options for dollar spot control. To reduce risk of resistance development and to manage fungicide resistance, a greater understanding of S. homoeocarpa population is needed. Our recent survey, based on invitro sensitivities to two systemic fungicides (thiophanatemethyl and propiconazole) using >1,400 S. homoeocarpa isolates collected from greens, fairways, and roughs of one of Massachusetts and six Wisconsin golf courses, indicated that the course age and fungicide history have no correlation with the frequency of thiophanatemethyl resistant isolates in the population. In case of propiconazole, the number of fungicide applications in the previous five years was not significantly related with reduced sensitivity. To examine genetic diversity of S. homoeocarpa population, isolates collected from the fairway and green of a university research facilities in Wisconsin were tested using inter simple sequence repeat (ISSR) markers. Two genetically distinct subgroups, which are vegetatively incompatible and have different fungicide sensitivities, coexisted on the fairway and putting green." |
