6种植物源化合物对南方根结线虫的毒性和温室防效研究
Nematicidal Activity of Six Phytochemicals against Meloidogyne incognita and Control Effects in Greenhouse
摘要
Abstract
The nematicidal activity and control effects of 6 phytochemicals against Meloidogyne incognita J2 were separately tested in glass culture dishes and greenhouse.The result showed that oxalic acid had the strongest inhibition activity,of which EC50 was 102.183 4mg/L.According to the inhibition activity,the order from big to small was oxalic acid＞crotonic acid＞tartaric acid＞ mandelic acid＞malic acid＞citric acid.The result in greenhouse indicated that the control effect of oxalic acid(76.8 ％) was the most significant and citric acid the lowest(10.4％).And the control effect order of 6 chemicals against M.incognita in greenhouse was consistent with that of their nematicidal activity.关键词
