| Abstract/Contents: | "Isolates of Rhizoctonia solani were collected from brown patch affected 'Caravelle' perennial ryegrass (Lolium perenne) in 1992 and 1993 and 'Bardot' colonial bent (Agrostis tenuis) plants in 1993, and their anastomosis groups (AG) were determined. Over seventy percent of all isolates (n=30) from Caravelle were AG-1 IA, and all isolates (n=20) from Bardot were AG-2-2 IIIB. Lower frequencies of AG-2-2 IIIB (n=6) and AG-4 (n=2) also were isolated from Caravelle perennial ryegrass. Nine isolates of AG-2-2 IIIB and one isolate of AG-1 IA were obtained from creeping bent (Agrostis stolonifera). Isolates of AG-1 IA and AG-2-2 IIIB were obtained from tall fescue (Festuca arundinacea) (n=12), and Kentucky bluegrass (Poa pratensis) (n=5). There was no seasonal variation in AG isolated. R. solani was isolated only three times from 540 crown or root samples from 135 naturally infected Caravelle or Bardot plants. Acremonium sp., Bipolaris sorokiniana, Curvularia lunata, C. senegalensis, Fusarium culmorum, F. oxysporum, Gaeumannomyces incrustans and Phoma sp. were isolated frequently from leaves, crowns or roots of perennial ryegrass and colonial bent plants affected with brown patch." |
