| Abstract/Contents: | "Turfgrass Rhizoctonia blight is a severe disease in golf courses in Korea. Attempts were made in 1989 to 1994 to identify the Rhizoctonia species associated with turfgrass blights and also to examine their epidemiology. A total of 120 Rhizoctonia isolates collected were identified as R. solani AG1, R. solani AG2-2, R. cerealis (AG-D) and R. oryzae from brown patch, large patch, yellow patch and white patch,m respectively, R. solani AG1 was mostly associated with brown patch of cool-season grasses, and most frequently isolated in June through July and also in September. R. solani AG2-2 was isolated exclusively from zoysiagrasses from April to November, most frequently in June through July and October through November. R. cerealis was isolated frequently from both creeping bentgrass in march through April and in November, and zoysiagrass in April and July. Thermophilic R. oryzae was isolated only from creeping bentgrass in August, although with very low frequency. R. solani AG2-2 was strongly pathogenic specifically to Korean lawngrasses(Zoysia japonica, Z. matrella, Z. tenuifolia), but non-pathogenic to creeping bentgrass(Agrostis palustris), bermuda grass(Cynodon dactylon), Kentucky bluegrass Poa pratensis), perennial ryegrass(Lolium prenne), and creeping red fescue(Festuca rubra subsp. rubra L.). R. cerealis was strongly pathogenic to zoysiagrass and bentgrass only, but was isolated-specific i.e., from non-pathogenic to pathogenic, for other turfgrasses. The mycelial growth was optimum at relatively high temperature ranges of 25-30°C for R. solani AG1, AG2-2 and R. oryzae, while the mycelial growth of R. cerealis was initiated at 5°C and almost ceased at of above 30°C." |
