The indole alkaloid venenatine exhibited antifungal activity against some plant pathogenic and saprophytic fungi. Venenatine in an aqueous acetic acid solution inhibited spore germination of all the 10 tested fungi, Fusarium udum, Alternaria brassicicola, Ustilago cynodontis and Aspergillus flavus showed an especially high sensitivity towards this compound, exhibiting germination levels below 10%. The spore germination and colony development of the parasitic fungus Erysiphe pisi, which causes powdery mildew in pea (Pisum sativum), on excised leaves of pea was also significantly affected. Pre-inoculation rather than post inoculation treatment of the leaves was more inhibitory against spore germination and colony development.
吲哚生物碱毒黎碱对一些植物病原真菌和腐生真菌表现出抗真菌活性。毒黎碱在乙酸水溶液中抑制了所有10种受试真菌的孢子萌发，其中乌德镰孢菌、芸苔链格孢菌、狗牙根黑粉菌和黄曲霉对该化合物表现出特别高的敏感性，萌发率低于10%。寄生真菌豌豆白粉菌可导致豌豆（豌豆属）白粉病，其在豌豆离体叶片上的孢子萌发和菌落发育也受到显著影响。叶片的接种前而非接种后处理对孢子萌发和菌落发育的抑制作用更强。
