将30种市售产品或采集的植物样品进行提取,把植物提取液加入培养基进行抑菌效果实验。对4种病原菌菌丝生长的测定结果表明,在30种供试植物中,大蒜(Allium sativum)提取液对粉红聚端孢霉(Trichothecium roseum)的抑制率达99.1%;蒲公英(Taraxacum mongolicum)提取液对有害疣孢霉(Mycogone perniciosa)抑制率达96.3%;石榴皮(Punica granatum)和龙葵(Solanum nigrum)提取液对蜡蚧轮枝菌(Lecanicillium fungicola)抑制率分别为85.2%和83.5%。但所有植物提取液对真菌轮枝霉(Verticillium fungicola)均无明显的抑制作用(<40.3%)。
Thirty commercial products or collected plant samples were extracted, and the plant extract was added to the culture medium for antibacterial effect experiments. The results of mycelial growth of the four pathogenic bacteria showed that the inhibitory rate of allium sativum extract on Trichothecium roseum was 99.1% among 30 tested plants, and that of Taraxacum mongolicum The inhibition rate of liquid to Mycogone perniciosa was 96.3%. The inhibitory rates of Punica granatum and Solanum nigrum extracts to Lecanicillium fungicola were 85.2% and 83.5% . However, all the plant extracts had no significant inhibitory effect on the fungus Verticillium fungicola (<40.3%).
