| Abstract/Contents: | "Dollar spot is a disease of turfgrass cause by Sclerotinia homoeocarpa (Bennett). The pathogen produces abundant mycelia on potato dextrose agar followed by a large plate-like irregularly shaped stroma embedded in the media. Tan foliar blight symptoms of dollar spot rarely exceed 5 cm on greens and fairways, and stroma are infrequently observed. Symptoms initially similar to those were observed in Florida on bermudagrass and seashore paspalum. The patches were larger than dollar spot rarely exceeding 9 cm in diameter, and affected turf turned nearly white with time. The most distinguishing feature of this disease was sclerotia-like structures with an average diameter of 0.2 mm were embedded in tissue of both hosts. The fungus isolated from these symptoms produced stroma of regular size (0.5 - 2.0 mm) in culture after 2 to 4 weeks. Isolates of this fungus and one S. homoeocarpa isolate were inoculated onto bermudagrass, seashore paspalum, and creeping bentgrass to test pathogenicity. Media type used to generate the inoculum had a significant effect on the amount of disease that occurred. Sterilized wheat seed inoculum produced the most disease. Symptoms occurred after 2 to 7 days, and the fungi were re-isolated from infected turfgrass. Inoculations were conducted three times with the same results. Future work will focus on morphology and genetic sequence of the anamorph. Initial results indicate the fungus is a previously undescribed Poculum species." |
