| Abstract/Contents: | "Brown patch caused by Rhizoctonia solani Kühn is seldom considered to be a major foliar disease of turfgrass in Alberta and Saskatchewan because of the generally direr conditions in these prariw provinces. However, spring and summer incidence of brown patch has been observed frequently in arid as well as more humid regions of the Prairies. Irregular parches of purplish green (smoky), wilted grass constituting 10-50% of lawns is not uncommon. The dead grass later becomes brown when dry. Although cariable in cultural characteristics, the isolates produce tan, wooly or cottony colonies and brwonish black sclerotia on PDA, and cylindrical to moniliform hyphae without clamps but multinumcleate cells. Spring and summer isolates are pathogenic to Kentucky bluegrass in controlled environment tests at 24° C. Fine mycelium and sclerotia are produced on inoculated grass after incubation for 10 d in humid chambers. Infected grass is smoky colored due to soft rot by the pathogen. Some isolates are capable of slow growth at low temperatures and, therefore, spring Rhizoctonia damage can be confused with the activity of snow mold pathogens that has occurred over the winter." |
