| 摘 要： | 本文用１０％溴氟菊酯乳油对甘蓝蚜进行了室内毒力测定和田间药效试验。试验结果表明：１０％溴氟菊酯乳油对甘蓝蚜的室内触杀ＬＣ５０为１１．７４２０ｍｇ／ｋｇ，而对比药剂２０％甲氰菊酯乳油的ＬＣ５０为２２．１２０８ｍｇ／ｋｇ，可见，１０％溴氟菊酯乳油的触杀作用明显高于２０％甲氰菊酯乳油。１０％溴氟菊酯乳油１０００×，２０００×稀释液，药后３天，５天对甘蓝蚜的防效均达到９０％以上，明显高于２０％甲氰菊酯乳油２０００ｘ稀释液８４．１％和８５．１％的防效。因此，建议田间使用１０％溴氟菊酯乳油２０００×稀释液防治甘蓝蚜为宜

| Abstract: | The test of control cabbage aphid with 10 percent brofluthrin EC was conducted.The result showed:(1)the contact LC 50 of fenpropathrin was 22.1208 mg/kg.Thus,it is obvious that the contact action of brofluthrin is higher than that of fenpropathrin.(2)the control effdct of each test was over 90% after 3 and 5 days of using 1000 and 2000 times diluents of 10 percent brofluthrin EC.These effects were higher than those of 20 percent fbnpropathrin EC 2000 times diluent which effects were 84 1% 85 1%.It is suitable to use 2000 times diluent in the filed. |
