Severe spotted lesions were observed on tulip plants grown in Asan, Yongin, and Icheon areas in Korea during a disease survey in 2000 and 2001. Diseased plants with severe symptoms were blighted and rotted at the late stage of disease development. A total of 15 isolates was obtained from the infected plant parts of tulip. All the isolates were identified as Botrytis tulipae based on their morphological and cultural characteristics. Three isolates of B. tulipae were tested for their pathogenicity to tulip by artificial inoculation. Spotted lesions similar to those observed in the fields were induced on tulip leaves. This is the first report of tulip fire disease caused by B. tulipae in Korea.
