Abstract/Contents: | "Several cultivars of Poa pratensis were evaluated for midsummer Helminthosporium sorokinianum (H. sativum) leaf spot. Field-plot evaluations of natural infections revealed that all cultivars were susceptible. Severity of midsummer H. sorokinianum leaf spot was minimal on Fylking, Glade P-29, and Pennstar; Nugget, Park, South Dakota Certified, Sydsport, and Delta were severely infected. It was concluded that the environmental conditions under which evaluations were made may have encouraged the near maximum expression of susceptibility among the cultivars. The general increase in the incidence of midsummer H. sorokinianum leaf spot on P. pratensis in Iowa is believed to be closely associated with irrigation practices and possible changes in virulence of the pathogen." |
