据国外W.B.Tappan研究报告,当使用乙酰甲胺磷防治烟草害虫时,收获的烟草经过加工后,烟叶中不会有药物残留。烟叶上发生的三种害虫是桃蚜、烟青虫和一种天蛾幼虫,经常使用乙酰甲胺磷喷雾或喷粉防治,一般整个生长期要喷施6、7次,每次用药量54.5—84克/亩。然后对所收获的青烟叶、烤烟和加工的雪茄烟叶进行检测乙酰甲胺磷和其代谢物 Ortho 9006(O,S-二甲基硫赶磷酰胺脂)的残留量,经两年检查,结 According to foreign W.B.Tappan research report, when using acephate to control tobacco pests, the harvested tobacco is processed and there is no drug residue in the tobacco leaves. The three pests that occur on tobacco are Myzus persicae, tobacco budworm and a hawk moth larvae, often using acephate spray or dusting control, the general growth period to be sprayed 6, 7 times, each dose of 54.5- 84 grams / mu. The harvested tobacco leaves, flue-cured tobacco and processed cigar tobacco leaves were then tested for residues of acephate and its metabolite Ortho 9006 (O, S-dimethylthio phosphoramidate) after two years of inspection and knot
