溴氰菊酯又叫敌杀死(Decig),是法国1975年研制成功的一种高效低毒、低残留的拟除虫菊酯类杀虫剂。目前,国际上生产和试产的拟除虫菊酯类品种达十多种,其中以2.5％溴氰菊酯乳剂最佳,有世界上最高效的杀虫剂之称。溴氰菊酯的化学名称为2—氰基—3—笨氧基苄基—(1R,3R)—3—(2,2—二溴乙烯基)—2,2—二甲基环丙烷羧酸脂。溴氰菊酯具有很强的杀虫力,对一般性害虫防治,用作叶面喷雾时,每亩仅用原药0.2—1.2克。其杀虫效果为DDT的100倍,西维因的80倍,马拉硫磷的50倍,对硫磷的40倍,其它拟除虫菊酯的5—10倍。
Also known as Decig, deltamethrin is a highly effective, low toxicity and low residual pyrethroid pesticide developed in 1975 by France. At present, there are more than 10 kinds of pyrethroids produced and trial-produced in the world, among which 2.5% deltamethrin emulsion is the best and the most efficient insecticide in the world. The chemical name for deltamethrin is 2-cyano-3-stupidoxybenzyl- (1R, 3R) -3- (2,2-dibromoethenyl) -2,2-dimethylcyclopropanecarboxylate Fatty. Deltamethrin has a strong insecticidal power, the general pest control, when used as foliar spray, the original drug only 0.2-1.2 grams per mu. Its insecticidal effect is 100 times that of DDT, 80 times of westvine, 50 times of malathion, 40 times of parathion, and 5-10 times of other pyrethrins.
