拟除虫菊酯(Pyrethroids,下简称PT)是七十年代迅速发展起来的第三代新型杀虫剂。其有效杀虫成份渊源于植物除虫菊花(Chrysanthemum Cinerariaefolium)的天然除虫菊素(Natural Pyrethrins)。PT系人工合成而与天然除虫菊素类似的化合物,目前至少有1000种,由于这类农药具有广谱、高效、低残留、易生物降解等特性,对短期或长期接触人群无明显的慢性毒作用或潜在的健康危害,多数动物实验证明为非致癌、致畸、
Pyrethroids (Pyrethroids, referred to as PT) is the rapid development of the seventies the third generation of new insecticides. Its effective insecticidal ingredient is derived from the natural Pyrethrins of Chrysanthemum Cinerariaefolium. PT is a synthetic compound with natural pyrethrins, at least 1,000 kinds of which have no obvious chronic toxicity to short-term or long-term exposure due to their broad spectrum, high efficiency, low residue and biodegradability Or potential health hazard, most animal experiments prove to be non-carcinogenic, teratogenic,
