为评价嘧菌环胺在设施栽培草莓上使用后的残留行为及环境安全性,依据《农药残留试验准则》,采用田间试验方法,研究分析了设施栽培条件下嘧菌环胺在草莓上的消解动态和最终残留情况,并以残留分析结果为依据,对实际生产上的用药情况进行调整,探索最适安全间隔期。结果表明,以800倍液施药1次,嘧菌环胺在设施栽培草莓上的降解半衰期为3.180天;随施药浓度和次数的增加,嘧菌环胺残留量和膳食风险会加大,因此,安全间隔期应适当延长。
In order to evaluate the residual behavior and environmental safety of cyproteronil on strawberry cultivated after application, according to the Pesticide Residue Test Guidelines, a field experiment was conducted to study the digestion of cyprodinil on strawberry Dynamic and final residues, and based on the residual analysis results, adjust the actual production of medication, to explore the optimal safety interval. The results showed that the half-life of cyproterone degradation was 3.180 days on the strawberry cultivated in 800 times with 800 times. With the increase of the concentration and times, the residues of cyprodinil and the risk of diet were increased, Therefore, the safety interval should be extended appropriately.
