Abstract
Sclerotinia rot was occurred on the leaf and stem of Peucedanum japonicum Thunb. in greenhouse field of Pohang city of Gyeongbuk province in Korea. The typical symptom of the disease was light brown spot and tipburn on infected leaves. The colony of the isolated fungus was white to light gray in color. Asci were cylindrical shape and 75‒240×5.9‒17.3 μm in size. Apothecia were cup-shaped with numerous asci and 0.5‒0.9 cm in size. Ascospores were aseptate and ellipsoid in shape, and 8.4‒10.7×4.8‒5.8 μm in size. Sclerotia formed on the plants and potato dextrose agar medium were globose to irregular in shape and black in color. Partial sequencing of rDNA of this isolate showed that it was 100% consistent with that of Sclerotinia sclerotiorum. It was confirmed that the same lesion was formed by reinoculating this pathogen on a healthy P. japonicum Thunb. and the same strain was isolated. This is the first report on the Sclerotinia rot of P. japonicum Thunb. caused by S. sclerotiorum in Korea.
Key Words: Peucedanum japonicum Thunb., Sclerotinia rot, Sclerotinia sclerotiorum
