Abstract: With the scarcity of wild medicinal plant resources and the increase in market demand, conventionally cultivated medicinal plants have become the dominant source in the market. However, due to soil degradation, imbalance in the rhizosphere microbial community, and the accumulation of allelopathic and autotoxic substances, root rot has emerged as a major disease in the cultivation of root- and rhizome-derived traditional Chinese medicines (RR-TCMs) in single, intensive, large-scale cultivation. It has a high incidence rate and is difficult to control, severely affecting the yield and quality of traditional Chinese medicines (TCMs). Currently, the application of microbial biocontrol agents in the control of diseases and pests of medicinal plants offers promising prospects for the sustainable development of TCMs. This paper presents a review of the antagonistic microorganisms and biological control mechanisms of root rot disease in RR-TCMs, aiming to provide a reference for the control of root rot.

Key words: root and rhizome, traditional Chinese medicines, root rot, biological control, yield, quality
