Sclerotinia Rot of Broad Bean (Vicia faba) Caused by Sclerotinia sclerotiorum
Jin Hyeuk Kwon, Yeoung Seuk Bae
Abstract
Sclerotinia rot occurred on the stem and pod of broad bean (Vicia faba) at Gyeongsangnam-do Agricultural Research and Extension Services in Korea from 2004 to 2006. The infected plants showed the typical symptoms; wilted, water-soaked, rotted and eventually died. The colony of the isolated fungus on PDA was white to faintly gray color. Apothecia were cup-shaped and 5~10 mm in size. Asci were cylindrical in shape and 90~180 × 8~12 μm in size. Ascospores were ellipsoid and 8~12 × 4~6 μm in size. Sclerotia formed on the PDA were globose to cylindrical or irregular in shape with black color. The optimum temperature for mycelial growth was 25oC and sclerotia formation was at 20oC on PDA. This is the first report on sclerotinia rot of broad bean (Vicia faba) caused by Sclerotinia sclerotiorum (Lib.) de Bary in Korea.
Key Words: Broad bean (Vicia faba), Sclerotinia rot, Sclerotinia sclerotiorum
