摘　　要：南方稻区使用噻枯唑防治水稻白叶枯病，在推荐剂量下，叶面喷雾，早、晚稻（叶）上残留随时间呈指数型模式降解，半衰期（Ｔ＿１／２）１．３４－４．３３ｄ。水稻全生长期使用８次之内，距收期２０ｄ，在稻米、谷壳中最终残留量皆低于ＭＲＬ值一个量级水平，从防治效果和安全使用上，是合理、可行的。Abstract Saikuzuo is used to protect rice from rice bacterial leaf blight in southof China Saikuzuo in rice was logistically degraded with time at suggesteddosage,Half life of Saikuzuo in rice was from 1.34 to 4.30 days.WhenSaikuzuo was sprayed tree times in rice growth period and 20 days beforeharvest,the final residues in rice and hask were less than MRL.
