摘　　要：本文通过敏感性测定和安全性试验，明确了水稻各类型品种对吡嘧黄隆的耐药性。研究结果表明，籼稻（早稻）品种耐药性较强，嘉籼７５—８、嘉育２９３在不同时期亩用１０％吡嘧黄隆１０～２０克，均表现安全；粳、糯稻（中稻、晚稻）品种耐药性较弱，宁６７、秀水１１、祥湖８４等在芽期使用或较高剂量使用，易产生明显药害。This paper is about the tolarence of different typesof rice ravieties to pyrazosulfron-ethyl by means of sensitivitydetermination and safety experiment.The result is as follows:Long-Shaped rice(early rice)had strong tolerance,Jiaxian75-8 and Jiayu 293 showed safe when pyrazosulfuron-ethyl10%WP was applied at 150 300g/ha in different growthstage. Round-Shaped rice and glutinous rice(semilate and laterice) had weaker tolerance. Ning 67,Xiushui 11 and Xianghu84 were easy to cause phytotoxility at higher dosage of pyrazo-sulfuron-ethyl.
