This article discusses the occurrence of Rhynchosporium orthosporum on Italian Ryegrass. In the second week of March 1960, stunted plants of S22 and HI strains of Italian ryegrass, Lolium miiltiflorum, were seen in a nine-acre field at Wadhurst in East Sussex, England. The foliage was chlorotic, with the older leaves brown and shrivelled. Affected plants were in several patches about one or two yards in diameter. Examination of individual leaves showed light green or greyish areas with irregular dark-brown margins and bearing cylindrical conidia which were mostly one-septate.
