溴氟菊酯防治果树、蔬菜上四种蚜虫的试验研究

Effective Tests on Brofluthrin Against Four Species of Aphids Feeding on Fruit Tree and Vegetable

１９９５年用１０％溴氟菊酯乳油１０００～３０００倍液对果树上的苹果黄蚜、桃蚜及蔬菜上的甘蓝蚜、菜缢管蚜进行了小区药效试验。结果表明：该药对上述四种蚜虫均具有良好的防治效果，明显优于２０％甲氰菊酯乳油２０００倍液，药后７天，１０００、２０００倍液对四种蚜虫防治效果均在９０％以上，对果树上的两种蚜虫持效期可达１４天左右。

ield tests with brofluthrin 10EC at 33～100 ppm to control Aphis pomi DeGeer,Myzus persicae(Sulzer) .Brevicoryne brassicae(L.) and Rhopalosiphum pseudobrassicae (Davis)were conducted in 1995. The results demonstrated that brofluthrin was highly effective for control of the four pests .the control efficacy was better than that of fenpropathrin 10EC at 100 ppm. The control efficacy of the chemical after seven days after spray at 50～100 ppm reached over 90%, and insecticidal action lasted for two weeks to fruit tree aphids.
