| Abstract/Contents: | "One hundred fifty-three isolates of Curvularia were collected from 415 turfgrass samples and 192 turfgrass seed samples. One hundred fifty-seven isolates were identified as C. lunata, four, C. geniculata, one C. intermedia, and one C. protuberata. These isolates were evaluated for pathogencity by inoculation on various cultivars of Kentucky bluegrass, creeping red fescue, and creeping bentgrass. The sources of inocula were conidial suspensions from 14-day-old colonies suspended in distilled water. The conidia were atomized on foliage and crowns of turfgrass, 16-18 weeks old, which had been grown in the greenhouse in pots. when plants were incubated at 20-24°C no visible symptoms of disease development were detectable after 10 days for any isolate tested. When plants were incubated at 24-31°C or at 29-35°C for 10 days most isolates induced some measure of disease development. Depending on the isolate, symptoms included leaf tip dieback, leafspots, and generalized blighting of crown tissues and leaf sheaths. One hundred twenty-one of the 147 isolates tested induced some form of symptom development. Various Curvularis isolates exhibited marked differences in virulence on the same grass cultivar. In addition, striking shifts in pathogencity occurred for the same isolate when inoculated on different grass cultivars and species." |
