摘要: 试验将黄柏皮、苦楝、大黄等活性植物醇提液的活性物质组合配比,进行室内抑菌优选试验。结果表明,最佳配方小檗碱含量为0.5%,并将其命名为0.5%小檗碱水剂。室内毒力、毒性测定及环境生物毒性试验表明,0.5%小檗碱水剂对多种靶标病菌有较高毒力,对人畜微毒,环境毒性为低毒或中等毒性。多点规模田间药效试验得出0.5%小檗碱水剂400倍对南瓜白粉病、辣椒疫病、莴苣菌核病防效均在75%以上。

Abstract: To clarify the bioactivities of the botanical substances against pathogens, the antibactierial effects of ethanol extracts of the bark of Chinensis Phellodendron, Melia azedarach, Rheum palmatum, et al. and their mixtures were studied. The results showed that the bioactivity of 0.5% berberine AS was highest to many fungi. It was also found that 0.5% berberine AS had high toxicities against some vegetable pathogenic fungi, slight toxicities against people and livestock and low biological toxicity to environment. All the efficacies of 0。5% berberine AS diluted to 400 times against Sphaerotheca fuliginea, Phytophthora capsici and Jclerotinia sclerotiorum, were above 75% in the field.

Key words: berberine, bioactivity, toxicity, field efficacy
