| 摘 要： | 选取7种植物源药剂与1种化学药剂(2.5%溴氰菊脂)对苜蓿蓟马Frankliniella occidentalis进行防治比较.结果表明,7种植物源药剂对苜蓿蓟马均有显著的防治效果,其中0.3%印楝素乳油、2.5%烟碱-楝素乳油、10%柠檬草乳油防效突出,与2.5%溴氰菊脂相比无显著差异,药后3 d的防效分别达到76.18%、63.42%和90.59%.此外0.3%印楝素乳油的药效持续时间长而10%柠檬草乳油的起效快.

| Abstract: | Field tests of comparing seven botanical insecticides to one chemical insecticide showed that seven botanical insecticides gave significant control.Especially 0.3% deltamethrin,2.5% nicotinamide-azadirachtin and 10% lemongrasstin had excellent control not significant different compared to 2.5% deltamethrim;3 days after treatment,control level attained were 76.18%,63.42%,90.59% respectively. |
