Abstract

Gray mold severely occurred up to 50% in freesia and gladiolus grown in the fields and greenhouses in Korea from 1998 to 2000. Symptoms appeared as spot and blight on leaves and flowers of infected plants. A total of 25 isolates was obtained from infected plant parts. All the isolates were identified as Botrytis gladiolorum based on their morphological and cultural characteristics. Gray mold symptoms similar to those observed in the fields and greenhouses were induced on the plants of freesia and gladiolus by artificial inoculation with four isolates of the fungus. This is the first report of gray mold of freesia caused by B. gladiolorum in Korea.

Key Words: Botrytis gladiolorum, freesia, gladiolus, gray mold
