| 摘 要： | [目的]为了评价吡蚜酮、异丙威在水稻上残留动态和环境安全性.[方法]2009-2010年在湖南、福建、广西进行了残留动态试验,建立了高效快速检测方法.吡蚜酮样品用乙腈-丙酮(体积比85∶15)提取,经Pesticarb/NH2柱净化,HPLC-UV检测;异丙威样品用丙酮、二氯甲烷提取,浓缩净化后,GC-FID检测.[结果]2年3地消解动态试验结果显示:吡蚜酮在土壤、植株中的残留消解半衰期分别为2.6～5.3、0.8～1.6 d;异丙威在土壤、植株中的残留消解半衰期分别为1.7～4.1、0.8～2.6 d.[结论]推荐剂量和1.5倍推荐剂量,各施药2、3次,收获期取样检测吡蚜酮和异丙威,各样品均未检测出.72％吡蚜酮·异丙威WG在水稻上使用安全.

| Abstract: | [Aims] The purpose of this paper was to study residual dynamics and environmental safety of pymetrozine and isoprocarb in rice eco-system.[Methods] The field trials on the dissipation and final residue of pymetrozine.isoprocarb 72% WG were carried out in Hunan,Fujian and Guangxi province during 2009-2010.The samples of pymetrozine were extracted with acetonitrile and acetone(85:15,by vol),concentrated and cleaned up by Pesticarb/NH2 SPE tubes,and determined using LC equipped with UV;the samples of isoprocar... |
