摘要
用10种不同溶剂提取的合欢叶、夹竹桃叶、蓖麻叶、马缨丹叶、黄花菊叶和黄花菊花粗提物(共60种) 对根结线虫二龄幼虫的生物测定结果表明,当合欢叶乙醇、甲醇、氯仿、乙酸乙酯、四氯化碳粗提物,马缨丹叶 甲醇粗提物,黄花菊花乙醇、丙酮、甲醇、乙酸乙酯粗提物相对植物粉浓度为2％时,对二龄幼虫具有较强的杀线 虫活性,24 h二龄幼虫死亡率均为100％。合欢叶和黄花菊花可能含有多种杀线虫活性成分。
In nematicidal activitiy of sixty plant crude extracts from Albizzia spp. leaf, Nerium indicum leaf,Ricinus communis leaf,Lantana indica leaf, Tithonia spp. leaf and Tithonia spp. flower extracted by ten different solvents were determined against the second juvenile (J2) of Meloidogyne spp..The result showed that the Albizzia spp. leaf ethanol, methanol, chloroform, ethyl acetate and carbon tetrachloride crude extracts, Lantana indica leaf methanol crude extract,Tithonia spp. flower ethanol, acetone, methanol and ethyl acetate crude extracts had stronger nematicidal activities against the J2. When concentration of these plant crude extracts were 2% (relating concentration of plant powder) , J2 mortality rate were 100% in 24 hours. Several nematicidal components may exist in Albizzia spp. leaf and Tithonia spp. flower.
