| Abstract/Contents: | "A new disease of creeping bentgrass caused by Drechslera catenaria is reported. The fungus, originally isolated from 'Toronto' creeping bentgrass, caused severe blight of all cultivars of colonial and creeping bentgrass that were artificially inoculated. D. catenaria caused reddish-brown necrotic lesions or "flecking" of tall fescue, red fescue and perennial ryegrass. Kentucky bluegrass cultivars were unaffected. Conidia are thin-walled, obclavate with hemiellipsoidal basal cells and are produced in chains in culture on lactose casein hydrolysate medium in light. A yellow-orange pigment diffused from colony on sucrose proline agar at 15 C in the dark. Conidia germinated more rapidly at 25 C than at 15 or 20 C on water agar. However, nearly all conidia germinated after about 2 hours at all temperatures tested. Appressorium formation occurred within 24 hours on detached leaves and penetration occurred between cells and through stomata." |
