Abstract

|
Sclerotinia rot symptoms were frequently found on the stems of Aster yomena in the Gurye region of Korea in April 2016. The symptom, watery soft rot, mainly appeared on the stems, and severely infected plants blighted. White mycelia spread over the stems of the infected plants and the soil surface. Small black sclerotia formed on the plant lesions and inside the diseased stems. Incidence of the disease was as high as 20~80% in the A. yomena fields. Based on the morphological and molecular characteristics of the isolates, the fungi were identified as Sclerotinia minor. This is the first report of Sclerotinia rot caused by Sclerotinia minor on A. yomena in Korea.
