| Abstract/Contents: | "Dollar spot (Sclerotinia homoeocarpa) is the most important disease on intensively-managed turfgrass in North America, such as golf course turf where multiple applications of fungicides are required during the growing season. Development of fungicide resistance in dollar spot is well documented and precludes effective disease management with fungicides. Genetic structure and in vitro fungicide sensitivity of S. homoeocarpa populations were investigated using a total of 287 isolates collected from fairways and putting greens at the O.J. Noer Turfgrass Research and Education Facility in Verona, WI. Analysis of genetic similarity among the isolates based on ISSR markers indicated the presence of two distinct groups (called A and B) comprising >90% of the isolates tested and little variation within each group. Over 95% of the isolates belonging to group B showed reduced sensitivity to thiophanate-methyl and propiconazole where as only 18% of the isolates in group A showed reduced sensitivity. A higher number of group B isolates than group A isolates existed on the fairway but more group A isolates colonized the green. The result indicates that different managements for a golf course fairway and green may provide environmental niches, which create S. homoeocarpa populations with unique genetic structure and fungicide sensitivity." |
