Glomerella cingulata (Stonem.) Spauld. & Schrenk에 의한 스타티스 탄저병

Anthracnose of statice (Limonium sp. var. Misty Blue and L. sinuatum Mill. cv. Early Blue) occurred up to 20% in vinyl-houses at Buan, Imsil and Namwon from July to November, 1993. All isolates from the anthracnose symptoms were identified as Glomerella cingulata (Stonem.) Spauld. & Schrenk and its anamorph was Colletotrichum gloeosporioides (Pens.) Sacc. Pathogenicity of the isolates was ascertained on the statice host by artificial inoculation. The symptoms on leaves appeared as circular brown spots in early stage and developed to zonate spots. The spot aggregated and diseased leaves were blighted. The symptom also developed on the stems of severely infected plants and the infected branches were blighted. A lots of acervuli developed on the lesions of stems. Acervuli on necrotic lesions were setose, rounded and elongated. Setae variable in length, 1~4 septate, brown, slightly swollen at the base and tapered to the apex on which conidia were occasionally borned. Statice was revealed as the new host of G. cingulata.
