摘要/Abstract

摘要： 在337和506 g·hm-2的施用剂量下，研究溴虫腈在温室和露地栽培西兰花花蕾和叶片上的残留动态。结果表明，溴虫腈在西兰花花蕾上的半衰期为77～173 d，在叶片上的半衰期为693 d。根据我国和日本、欧盟的残留限量标准，建议温室和露地栽培西兰花，当溴虫腈用量为337～506 g·hm-2，施用1次时，建议安全间隔期为14 d，可满足国内消费和出口欧盟的标准。由于溴虫腈在西兰花叶片残留量高且降解缓慢，因此在此剂量下使用的西兰花叶片不能食用。

Abstract: In the present study， the initial deposition of chlorfenapyr in broccoli was set as 337 and 506 g·hm-2 to study the residues and dissipation dynamics of chlorfenapyr in broccoli flowers and leaves under both greenhouse and open field conditions. The result showed that the half life of chlorfenapyr in broccoli flowers was 77-173 d，and was 693 d in leaves. According to the maximum residue limits （MRLs） of China，EU and Japan， with the use dosage of 337-506 g·hm-2 and 1 time application，the pre\|harvest interval （PHI） of chlorfenapyr in broccoli flowers was suggested to be 14 d，in order to meet the standards of domestic consumption and exportation to EU. As the residue of chlorfenapyr in broccoli leaves was relatively high and hard to dissipate，broccoli leave was not suggested for consumption with this application dosage.
