Abstract
Anthracnose symptoms on Spiraea prunifolia were observed around the residential area of Dongbumyon, Geoje City, Gyeongnam Province, Korea in 2002 and 2003. Typical symptoms of the disease were dark red spot on the leaves and black spot on the stem. The pathogen formed gray to dark gray colony on potato dextrose agar. Conidia were single celled, color, ovoid or oblong in shape and $6{\sim}12\;{\times}\;3{\sim}5\;{\mu}m$ in size. Seta were dark brown in color, cone-shaped in shape and $23{\sim}42\;{\times}\;2{\sim}4\;{\mu}m$ in size. The optimum temperature for growth of the isolate was about $25{\sim}30^{\circ}C$. On the basis of mycological characteristics and pathogenicity test on host plants, the fungus was identified as Colletotrichum gloeosporioides. This is the first report on the anthracnose of S. prunifolia caused by C. gloeosporioides in Korea.
