| Abstract/Contents: | "Rhizoctonia solani isolates were obtained from creeping bentgrass exhibiting brown patch symptoms in two locations within North Carolina, Sandhills Research Station (SRS; 59 isolates) and Country Club of North Carolina (CCNC; 41 isolates). All isolates belonged to AG-2 based on nuclear status and anastomosis reaction. Analysis of ITS sequences placed all isolates from CCNC in AG-2-2-IIIB. Isolates from SRS formed a clade within AG-2-2 that was distinct from all known subgroups. SRS isolates produced colonies that were medium brown with brown sclerotia in concentric circles, while AG-2-2-IIIB colonies were dark reddish brown with dark brown sclerotia produced at the center and periphery of the plate. SRS isolates exhibited reduced growth rate at 12°C and increased growth rate at 36°C compared to AG-2-2-IIIB. AG-2-2-IIIB isolates caused higher disease incidence (70-80%) on creeping bentgrass seedlings at 25°C than SRS isolates (50-63%). We propose that the SRS isolates represent a novel subgroup of R. solani designated AG-2-2-V." |
