摘要

[Objective] The paper was to explore the herbicidal effects of Periconia heveae culture filtrate on Mikania micrantha. [Method] Through indoor bioassay method, the inhibition effects of culture filtrates of seven species of plant disease fungi on seed germination and seedling growth of M. micrantha were studied, and the security of P. heveae culture filtrate on pepper (Capsicum annuum) and tomato (Solanum lycopersicum) was also evaluated. [Result] The culture filtrates of P. heveae had strong inhibition effects on seed germination and the growth of root, shoot and seedling of M. micrantha, and the inhibition rates were 72.7%, 93.0%, 32.4%, and 54.6% (fresh weight), respectively. Security tests showed that culture filtrates of P. heveae were safe to seed germination and root and shoot growth of tomato, and the growth rate had no significant difference with control, but they inhibited seed germination of pepper. [Conclusion] As potential biological herbicide, the culture filtrate and metabolites of P. heveae is worthy of further development. .
