摘要:

为寻找新型植物源杀线虫活性物质,测定了22种植物甲醇提取液对南方根结线虫2龄幼虫的毒杀效果。试验结果表明:紫茎泽兰、蕺菜、草麻黄、马钱、半夏、艾蒿、小米椒、大蒜等8种植物在48 h内对线虫的校正死亡率在50%以上,具有较强的杀线虫活性;蕺菜对线虫的校正死亡率在24 h4、8 h内均达到100%,具有极强的杀线虫作用。

Abstract:

In order to search for a new plant-based nematicidal active substance, the toxic effects of methanol extracts from 22 species on the 2nd-instar larvae of Meloidogyne incognita were determined. The test results showed that the corrected mortality of eight species of Eupatorium adenophorum, Eupatorium chinense, Ephedra, Machilus, Pinellia, Artemisia annua, Xiaomijiao, garlic and so on within 48 hours was above 50% Of the nematicidal activity; the correct mortality of B. inciseatus nematodes in 24 h 4,8 h 100%, with a very strong nematicidal effect.
