速灭杀丁又称杀灭菊酯,化学名称为α-氰基-3-苯氧基苄基-2-(4-氯苯基)-3-甲基丁酸酯,是我国重点发展并已生产的拟除虫菊酯。它是高效广谱杀虫剂。经我所的药效试验表明,按有效成分计算,速灭杀丁每亩用量2.5-5克。对烟青虫、烟蚜有较好的防治效果,防效均达90%以上。为了制订出该农药在烟草上的安全使用标准.我们于1983-1984年对其在烟草中的残留动态进行了研究。
Speed kill kill Ding also known as fenvalerate, chemical name is α-cyano-3-phenoxybenzyl 2- (4-chlorophenyl) -3-methyl butyrate, is China’s key development and Pyrethroids have been produced. It is a highly effective broad-spectrum insecticide. The efficacy of our tests show that, according to the calculation of active ingredients, the rate of immediate use kill 2.5-5 grams per mu. On tobacco budworm, aphids have better control effect, control effect reached more than 90%. In order to establish the standard of safe use of the pesticide on tobacco, we studied its residual activity in tobacco from 1983 to 1984.
