58种中(草)药对植物寄生线虫Meloidogyne javanica和Pratylenchu svulnus的药效研究

STUDY OF THE EFFECT OF 58 CHINESE HERBAL MEDICINES ON THE PLANT PARASITIC NEMATODES, Meloidogyne javanica AND Pratylenchus vulnus

为寻找化学杀线虫的替代物 ,首次进行中国草药杀植物寄生线虫试验 ,从 50 0多种有记载的杀线虫和昆虫的中草药中挑选 58种进行筛选试验。研究表明 ,在试验条件下 ,2 2种中草药能杀死根结线虫 Meloidogyne javanica,2 6种对短体线虫 Pratylenchus vulnus有很强药效 ,其中 9种明显杀死它们。试验还指出 ,大部分中草药都有不同程度的麻醉作用 ,受麻醉作用的线虫当转入水中后会复苏并恢复活力 。

WT5BZ]We introduce the idea of using Chinese traditional herbal medicines as alternatives to the nematicides currently used in agriculture for the management of plant parasitic nematodes.We tested 58 of the approximately 500 herbal remedies documented to kill worms in humans,or insects, for their effects on Meloidogyne javanica and Pratylenchus vulnus .Twenty two of the remedies killed M.javanica juveniles.Twenty six of the remedies strongly affected P.vulnus, and nine were toxic.In many cases the herbal medicines had a narcotic effect and the nematodes recovered activity when placed in water.The narcotic effect varied with medicines and increased with time of exposure.
