Soybeans are an important crop known to harbour a complex of Diaporthe and Phomopsis species. This complex has been reported to be involved in several soybean diseases, including Phomopsis seed decay. In this study, two species of Diaporthe/Phomopsis fungi from soybean plants were identified by morphological and molecular characterizations. Koch's postulates were confirmed by pathogenicity tests on hypocotyls of soybean seedlings. Phomopsis longicolla was found to be the most common and virulent pathogen to soybeans in Korea. Phomopsis sp., which was considered as a new soybean pathogen, might have been introduced from other plants given that similar strains of Phomopsis sp. have infected fruit trees in China, Japan and Portugal and vegetable plants in the United States.
