有机磷除草剂胺草灵(Amiprophos)的化学结构、性质以及除草性能等均见本卷上期“除草剂胺草灵毒性试验”一文。其急性毒性按急性毒性分级属低毒性类。我们在做该药迟发性神经毒性试验时,发现该药对公鸡有性腺毒作用,表现在公鸡不再啼叫,鸡冠萎缩下垂,睾丸明显萎缩,睾丸脏器系数比对照组小5～6倍。化学致突变原在小白鼠精子形成的某些阶段能诱发突 The chemical structure, properties and herbicidal properties of the organophosphorus herbicide Amiprophos are described in the article “Herbicide Aminetotoxicity Test” in this volume. Acute toxicity according to acute toxicity classification is a low toxicity class. We are doing the drug delayed neurotoxicity test and found that the drug on the rooster has gonadal toxicity, the performance of the cock is no longer crowing, cock crowding atrophy, testicular atrophy, testis organ coefficient than the control group 5 to 6 Times Chemical mutagenesis in the mouse spermatogenesis in some stages can induce sudden
