Abstract/Contents:Provides a study conducted by the University of Guelth in Ontario, Canada on "the ectotrophic, root-infecting fungus Magnaporthe poae Landschoot & Jackson, the casual agent of summer patch disease in the U.S. [United States] (2), is implicated in the damage and loss of annual bluegrass (Poa annua L.) on golf course greens." Details the methods and materials used in the study, stating that "over 100 turf samples that exhibited symptoms (chlorotic circular or irregular patches ≥ 15 cm in diameter with necrotic crowns and discolored roots) reminiscent of summer patch were collected from 77 southwestern Ontario golf courses from July to August of 2009 and 2010." Reports that "after 2 to 3 weeks, inoculated plants exhibited chlorotic foliage and necrotic roots covered with dark ectotrophic runner hyphae and lobed hyphopodia. Infected root sections from each replication were surface sterilized and placed on PDA containing 50 mg L-1 streptomycin sulfate." Concludes that "to our knowledge, this is the first report of summer patch caused by M. poae in Canada."
