| Abstract/Contents: | "Magnaporthe poae Landschoot & Jackson, the cause of summer patch, was isolated from symptomatic annual bluegrass (Poa annua L.) in golf course putting greens at Cincinnati and Columbus during the summer of 1988. Small (<15) chlorotic patches typical of the early symptoms of summer patch consisted of plants with decayed crowns and discolored roots covered with dark ectotrophic hyphae. The teleomorph, required for accurate identification, was produced in vitro (acidified potato-dextrose agar) only when paired with the compatible mating type. Perithecia, asci with refractive apical rings, and ascospore morphology and measuremets were similar to those reported by Landschoot and Jackson. Pathogenicity of Ohio isolates was verified with Kach's postulates in greenhouse studies. Kentucky bluegrass (P. Pratensis L. 'S-21') and P. annua were inoculated with millet seed infested with M. poae at the time of planting in sterilized sand. This is the first published report of M. poae in Ohio." |
