| Abstract/Contents: | "Fusarium roseum was found capable of inciting severe foliar blighting of certain turfgrasses. Foliar infection by the pathogen is accomplished by both direct penetration of intact epidermal cells and by mycelial growth through cut leaf tips. Virulent strains of the organism have been isolated from commercial turfgrass seed lots. Using dew cabinets for post inoculation environment, the interactions of three air temperatures (75°F. 85°F., 92°F), three F. roseum isolates and three turfgrass species (Highland bentgrass, Merion Kentucky bluegrass, and Illahee fescue) were studied. Quartz sand was used as the plant support medium and irrigations were accomplished with balanced Hoagland's solution. The inoculum was prepared by growing the isolates on a corn meal-sand medium. Inoculations were preformed eight weeks from the time of seedling emergence. Disease incidence was rated on the basis of percentage plants blighted. Within the temperature range studied, all isolates were pathogenic to all turfgrass species. At certain air temperatures, however, the isolates differed significantly in degrees of virulence." |
