摘要
１９９２～１９９５年用１０％溴氟菊酯乳油对大豆食心虫、大豆蚜、甘蓝夜蛾进行了小区试验。结果表明，该药对上述三种害虫具有良好的防效。ｌ０００倍液对大豆食心虫防治效果与２０％甲氰菊酯乳油２０００倍液相当，达到３９２．９％以上；用１０００～２０００倍液防治大豆蚜，药后７天防效达８８．５％以上；用５００～１５００倍液防治甘蓝夜蛾，药后７天均达到了８４．６％以上的防治效果。而且对作物安全。
ield trials with brofluthrin 10EC to control the soybean pod borer (Leguminivoia glycinivorclla Matsumura).the soybeans aphid (Aphis glycincs Matsumura) and the cabbage army worm (Mamestra brassicae L.) were carried out in 1992～1995. The results showed that the chemical was an effective insecticide for controlling these three pests. The control efficacy for the soybean pod borer at 100ppm was similar to that of fenpropathrin 20EC at 100ppm and reached over 92. 9%. The control efficacy after seven days of spray at 50～100ppm for the soybean aphid was over 88. 5% and at 67～200ppm for the cabbage army worm was over 84. 6%,and no side-effect on growth of the test crops was found.
