近几年来,中国农药行业通过产品结构调整,高毒农药所占比例虽然有大幅下降,但仍有杀扑磷、甲拌磷、甲基异柳磷、克百威、灭多威、灭线磷、涕灭威、磷化铝、氧乐果、水胺硫磷、溴甲烷、硫丹等12个高毒品种,产量约占农药总产量的2.5%左右。中国是农药生产、使用和出口大国,目前已形成包括农药原药生产、制剂加工、原料中间体生产及研发在内的完整工业体系。随着农药工业的快速发展,环保问题也日益突出。化学合成农药步骤多、收率较
In recent years, China’s pesticide industry through product mix adjustment, although the proportion of highly toxic pesticides have dropped significantly, but there are still killing the phosphorus, phorate, methylisophthalone, carbofuran, methomyl, Phosphorus, aldicarb, aluminum phosphide, omethoate, isocarbophos, methyl bromide, endosulfan and other 12 highly toxic varieties, accounting for about 2.5% of the total output of pesticides. China is a big country for the production, use and export of pesticides. At present, China has formed a complete industrial system that includes the production of pesticides, the preparation and processing of raw materials, the production and research and development of raw material intermediates. With the rapid development of pesticide industry, environmental issues have become increasingly prominent. Chemical synthesis of pesticides more than the yield
