Abstract

Anthracnose symptoms were observed on the community area in Sancheong-gun, Gyeongnam Province in Korea. The symptoms occurred on leaf and stem, and then plants eventually were died. Colony color was whitish gray to dark gray on potato dextrose agar. Conidia were single celled, colorless, cylindrical and was 10.2~20.4×3.6~6.0 mm in size. Appressoria were dark brown, ovate to obovate and 6.2~10.5×4.3~8.6 mm in size. Perithecia were brown to black in color and shaped as globose to obpyriform and 72.6~284.7 mm in size. Asci were clavate to cylindrical in shape and 63.6~98.8×8.3~12.5 mm in size. Ascospores were cylindrical, fusiform, slightly curved at the center and 9.6~21.8×4.0~6.0 mm in size. Optimum temperature for growth was 30℃. On the basis of mycological characteristics and pathogenecity test on host plants, the fungus was identified as Glomerella cingulata. This is the first report on the Anthracnose of achyranthes caused by Glomerella cingulata in Korea.
