| Abstract: | Panax notoginseng is a highly valuable herb, but root rot disease severely impairs its development and decreases the yield and quality of roots. In this study, a fungal isolate (3A-2-2) was obtained from P. notoginseng seedlings with root rot symptoms and was identified as Plectosphaerella plurivora based on morphological characteristics and molecular analysis. The fungal isolate 3A-2-2 could cause root rot disease and be re-isolated, fulfilling Koch's postulates. This is the first study to report on root rot disease caused by P. plurivora on P. notoginseng in China. |
