| Abstract/Contents: | "Seven grasses in 18 mixtures were studied under heavy shade (5% of incident sunlight) provided by mature maple trees. The area received only natural rainfall, was cut at a 2-inch height, and received 2# of nitrogen per 1,000 square feet per year. Three years results show disease incidence to be the major factor influencing adaptation. Powdery mildew (Erysiphe graminis) infection of common and Merion Kentucky bluegrasses resulted in 98% loss of stand with no recovery in subsequent years. Pennlawn red fescue showed a 90% reduction in stand due to leafspot (Helminthosporium sativium) but exhibited over 50% recovery the subsequent spring. However, each year reinfection occurred with the advent of warmer weather. Kentucky 31 tall fescue, common perennial ryegrass and Norlea ryegrass performed poorly due to snow mold (Typhula spp.) and low temperature injury during the winter period. Roughstalk bluegrass produced an acceptable turf for two summers but was severely thinned by disease in the third year which correlated with thatch accumulation. The higher humidities, extended dew periods and more succulent growth in shade resulted in disease being a more important factor in adaptation than light intensity or moisture." |
