为评价联苯肼酯在草莓上的环境安全性，采用田间试验方法，研究了设施栽培条件下联苯肼酯在草莓上的消解动态和残留情况，并据此对实际生产中的用药模式进行调整，探索最适安全间隔期。结果表明，联苯肼酯2000倍液施药1次，其在设施栽培草莓上的半衰期为3.15 d；设施栽培草莓上联苯肼酯的残留量受施药浓度、施药次数影响，残留风险与田间用药剂量、用药次数呈正相关。参考国外农药残留限量标准，建议在设施栽培条件下，按常规方法及作用剂量施药；在施药2～3次的情况下，草莓的安全采收间隔期为3d；随着施药浓度或施药次数增加，安全间隔期应适当延长。

In order to determine the environmental safety of bifenazate , the dynamic changes of bifenazate residue on strawberry was studied under greenhouse condition .Meanwhile , the safe application mode of bifenazate and proper harvest interval of strawberry was explored .It was shown that the half-life of bifenazate in strawberry was 3.15 d when it was applied once in 2 000 times diluents.The final bifenazate residue was influenced by both the application concentration and application times , and the environment risk was positively correlated with the application dosages and times.When bifenazate was applied 2 or 3 times at the recommended concentration on strawberry , the proper post-harvest interval was 3 d, and the harvest interval should be appropriately extended with the increased application dosages and times .
