Observation reveals significant root rot disease incidence in Polygonatum cyrtonema, indicating urgent control measures are needed.

The incidence of root rot reached approximately 42.5%, dramatically impacting both yield and quality of Polygonatum cyrtonema.
PCR analysis confirmed the causal organism as Clonostachys rosea with a 99.81% match in sequence databases.
The pathogenicity test showed that inoculated roots developed symptoms consistent with field observations after 15 days.
The findings mark the first documented case of Clonostachys rosea root rot impacting Polygonatum cyrtonema in China, highlighting the need for preventive measures.

Liu et al. (2025) studied this question.
