| Abstract/Contents: | "The distribution of three Ophiosphaerella spp. that cause spring dead spot (SDS) of bermudagrass was studied by sampling at 24 locations in the southeastern United States. O. korrae was isolated from 73% of the 204 bermudagrass cores collected and was the only SDS pathogen recovered at most sites. O. herpotricha was isolated at three locations in Kentucky and one in North Carolina, and O. narmari was found at two locations in North Carolina. Most O. korrae isolates collected from Alabama, Kentucky, Mississippi, Tennessee, and Virginia clustered in an amplified fragment length polymorphism group (AFLP group II) that was distinct from Kentucky bluegrass isolates collected throughout North America and similar to bermudagrass isolates from Kansas and Oklahoma (AFLP group I). A third AFLP group (III) consisting of bermudagrass isolates from Mississippi and Virginia was identified. Isolates representing AFLP groups II and III grew more rapidly on potato dextrose agar at 25 and 30°C than those in group I. O. korrae isolates differed in their aggressiveness to two bermudagrass cultivars in greenhouse studies, but these differences were not associated with AFLP group, location, or host from which the isolate was collected." |
