| Abstract/Contents: | "Determining anastomosis groups may provide valuable information relative to host range, pathogenicity and fungicide sensitivity of Rhizoctonia solani Kuhn. R. solani isolates were obtained from turfgrasses affected with brown patch in Maryland in 1992 and 1993. Three methods (i.e., cellophane strip, clean glass slide, and petri dish) were compared for their ease in identifying R. solani anastomosis groups. Growing isolates in a petri dish with a thin layer of water agar was the most simple and reliable method. R. solani isolates belonging to AG-1 were most frequently obtained from perennial ryegrass (Lolium perenne L.) and AG2-2 isolates were commonly identified from bentgrass (Agrostis spp.). Lower frequencies of AG2-2 and AG-4 also were isolated from perennial ryegrass. From a total of 810 samples of crown or root tissue obtained from diseased perennial ryegrass or colonial bentgrass (A. tenuis Sibth), only two isolates of R. solani were obtained from crowns of colonial bentgrass and perennial ryegrass and one from root tissue of perennial ryegrass. All of these isolates belonged to AG2-2. Bipolaris sp., Curvularia spp., Fusarium spp., Phoma sp., Acremonium sp., Gaeumannomyces sp., and Phialophora sp. were frequently isolated from leaves, crowns or roots of perennial ryegrass plants affected with brown patch." |
