| Abstract/Contents: | "Curvularia species are ubiquitous and are typically considered to be secondary pathogens or saprophytes. A foliar blight of zoysiagrass has been observed in NC since 2002. The disease is most active when temperatures are 21 °C to 30 °C. Initial symptoms normally appear as small, chocolate brown spots with dieback from the tips. Continued infection can result in blighting of irregular patches up to 15 cm in diameter. Microscopic analysis revealed Curvularia conidia consistently associated with the disease. To determine the pathogenicity of these fungi, twenty-one isolates were obtained from 6 locations. Analysis of ITS rDNA sequences indicated 2 isolates most closely related to C. lunata while other isolates appeared more closely related to C. pallescens. Spore morphology was consistent with C. lunata for all isolates. Pots of 'Emerald' and 'El Toro' zoysiagrass were inoculated with one of five C. lunata isolates in greenhouse at 26C. Isolates varied in aggressiveness, inducing symptoms in 1 to 3 weeks. Continued disease progress resulted in blighting similar to that observed in the field. This is the first report of Curvularia blight of zoysiagrass in the United States, it was previously reported in Japan, where is is called 'dog footprint'." |
