Occurrence and management of root rot disease of Panax notoginseng in China

摘要

Panax notoginseng is an important medicinal herb cultivated only in the limited mountainous areas of Yunnan, China. However, its production is severely limited by disease because of the length of propagation in warm, humid, and shaded environments. Root rot is an increasingly serious problem due to a lack of proper rotation in recent years. Disease incidence ranges from 10% to totally infected. In view of its serious importance, studies on the causal microorganisms, infection cycle and management were undertaken. This paper presents some of the results obtained.
