Ginseng ( Meyer) is an invaluable medicinal plant containing various bioactive metabolites (e.g., ginsenosides). Owing to its long cultivation period, ginseng is vulnerable to various biotic constraints. Biological control using endophytes is an important alternative to chemical control.
In this study, endophytic PG87, isolated from mountain-cultivated ginseng, was evaluated for biocontrol activity against six major ginseng pathogens. exhibited antagonistic activity with mycoparasitism against all ginseng pathogens, with high endo-1,4-β-D-glucanase activity.
inoculation significantly reduced the disease symptoms caused by and and induced ginsenoside biosynthesis in ginseng plants. was formulated as dustable powder and granules. The formulated agents also exhibited significant biocontrol activity and induced ginsenosides production in the controlled environment and mountain area.
Our results revealed that has great potential as a biological control agent and elicitor of ginsenoside production.
人参（迈耶）是一种珍贵的药用植物，含有多种生物活性代谢物（如人参皂苷）。由于其生长周期长，人参易受各种生物胁迫。利用内生菌进行生物防治是化学防治的重要替代方法。
在本研究中，从山地栽培人参中分离出的内生菌PG87，对六种主要人参病原菌的生物防治活性进行了评估。对所有参病原菌均表现出具有重寄生作用的拮抗活性，具有较高的内切-1,4-β-D-葡聚糖酶活性。
接种显著减轻了由[病原菌名称缺失]和[病原菌名称缺失]引起的病害症状，并诱导人参植株中人参皂苷的生物合成。PG87被制成可湿性粉剂和颗粒剂。这些制剂在控制环境和山区也表现出显著的生物防治活性，并诱导人参皂苷的产生。
我们的结果表明，PG87作为一种生物防治剂和人参皂苷生产诱导剂具有巨大潜力。
