Abstract/Contents:"Sclerophthora macrospora (Sacc.), the incitant of downy mildew in many grass species, has been observed in association with 'Meyer' zoysiagrass (Zoysia japonica Steud.) in eastern Missouri and western Illinois. The first reports of yellowing were received in 1995. The symptoms occur in the early spring or in early fall on shaded areas of zoysiagrass fairways. From a distance the affected turf is freckled, with yellow tufts interspersed with green, healthy grass. Occasionally the yellowing is more diffuse, with no well-defined tufting. Tufting corresponds to multiple tillers at individual nodes. As many as 40 tillers have been observed at a single node. In April 1999 and again in April 2000, sporangia conforming to the size range and morphology of S. macrospora were observed on infected leaves. The disease appears to be a cosmetic problem, although individual tufts sometimes die because of poor rooting."
