Abstract:

Members of the genus Coptis, in the Ranunculaceae family, are perennial herbaceous plants commonly known for their medicinal properties. Fungal diseases are among the main types of plant diseases and they limit the production of Coptis species. The planting area of Coptis in China is approximately 10000 ha. To date, there has been limited research on its fungal diseases. To provide a background for research on the fungal diseases of Coptis in the future, we have summarized the results of domestic and international research, describing the types of diseases and pathogens, their distribution, damage, and occurrence patterns, current control methods, and other relevant problems. As of 2025, 40 diseases caused by 32 fungal species have been identified on 10 Coptis species, distributed across six countries and 10 regions. These include 27 foliar and stem diseases and 13 root diseases. Among them, 15 diseases were reported only abroad, while 25 were reported exclusively in China, with the highest number (16) in Chongqing. Research on the fungal diseases of Coptis abroad is limited. In China, studies have focused mainly on anthracnose, leaf spot, powdery mildew, southern blight, and root rot, and have described occurrence patterns, impacts, and control measures. Research on the pathogenic mechanisms remains insufficient. It is recommended to focus on major diseases affecting Coptis production, clarify pathogen taxonomy, conduct detailed studies on occurrence patterns and pathogenic mechanisms, and evaluate the effects of plant diseases on active medicinal compounds. In addition, it is important to generate new disease-resistant varieties and develop effective disease control strategies to promote sustainable Coptis production.
