摘要
利用4种农药混用和单用对菜青虫、斜纹夜蛾和小菜蛾进行了田间药效试验。结果表明，农药混用效果显著优于各药剂单用效果。其中48%乐斯本乳油与10.8%凯撒乳油混用对3种害虫有特效，速效性好，持效期长达7d(天)。48%乐斯本乳油与5%卡死克或5%抑太保乳油两种混用对3种害虫防效高，持效期长达7～10d(天)，但防治斜纹夜蛾、小菜蛾的速效性差。
The field tests of Pitris rapae，Prodenia litura a nd Plutella xylostella control with Lorsban 4 E，Cesar 10.8 EC，Flufenoxuron 5 EC and Atabron 5 EC were conducted. The results showed that the control effec ts of mixed pesticides were much better than each single one. The mixture of Lor sban and Cesar had special efficiency，fast acting and durability (7 days) on abov e three pests. The mixture of Loraban and Flufenoxuron or Atabron also had good efficiency and durability (7-10 days)，but slow acting on Prodenia litura and Plutella xylostella.
