目前,DDT等有机氯农药已在我国停止生产,迫切需要研制低残毒的农药取代之。但这往往需要的时间较长,资金多。如能尽量利用DDT的生产设备、原料,生产国外已商品化的低残毒品种,当然也是一种切实可行的方法。为此我们曾合成了甲氧DDT。虽然甲氧 At present, DDT and other organochlorine pesticides have been discontinued in China, and there is an urgent need to develop low-residue pesticides to replace them. But this often takes longer, more money. If we can make full use of DDT’s production equipment, raw materials, the production of foreign commercial low residue varieties, of course, is also a viable method. To this end we have synthesized methoxy DDT. Although methoxy
