| Abstract/Contents: | "The aggressiveness of Ophisophaerella korrae, O. herpotricha, and O. narmari, the pathogens that cause spring dead spot (SDS) of bermudagrass (Cynodon dactylon) and its hybrids, were evaluated following inoculation of bermudagrass swards at two locations in Kansas and one in Oklahoma. In general, O. herpotricha resulted in the highest proportion of dead spots and the largest patch diameters of the three SDS pathogens. Pathogenicity of O. korrae isolates was highly variable. Some isolates were non-pathogenic whereas others caused dead spots that increased yearly in size, but at a slower rate than those caused by O. herpotricha. The O. narmari isolates were either non-pathogenic or only weekly aggressive. A unique Ophiosphaerella was isolated from diseased bermudagrass in Kentucky. The fungus was closely related to other Ophiosphaerella species that cause SDS based on rDNA ITS sequence analysis. Nevertheless, the sequence was sufficiently different to indicate that this fungus is distinct form O. narmari, O. herpotricha and O. korrae. Attempts to produce ascocarps of this fungus in vitro were unsuccessful." |
