Stemphylium vesicarium on Garlic and other Allium spp. in Korea

마늘 및 기타 Allium속 식물에 발생하는 Stemphylium vesicarium

More than 100 isolates of Stemphylium obtained form leaf blight lesions of garlic (Allium sativum), onion (A. cepa) and leek (A. fistulosum) were identified as Stemphylium vesicarium (Wallr.) Simm. based on various morphological characteristics rather than S. botryosum Wallr. previously reported on those plants in Korea. In controlled inoculations, the pathogen induced the disease symptoms on leaves of garlic 7 days after inoculation. Onion and leek were also artificially infected by the fungus. This is the first report of S. vesicarium causing a leaf blight of garlic, onion and leek in Korea.
