- Abstract
- Stem rot symptoms of common bean occurred sporadically in Jinju, Korea. The typical symptom included water-soaking on the main stem, rotting, wilting, and blighting, which eventually leads to death of the plant.
The sclerotia, white to brown, spherical with size of 1−3 mm, formed over lesions and surface soil line. The optimum temperature for mycelial growth and sclerotia formation was 30oC on potato dextrose agar (PDA).
The typical clamp connections were observed in the hyphae of the fungus grown on PDA. Mycological characteristics and pathogenicity to host plants indicated that the fungus was Sclerotium rolfsii Saccardo.
This is the first report of stem rot on common bean caused by S. rolfsii in Korea.
