摘　　要：[ Objective] Residue condition of thiacloprid in soil and rice was studied. [ Method] The residue decline of 480 g/L thiacloprid SC in rice soil and the final residue in rice was studied through crop field trials and liquid chromatography analysis. [ Result] Crop field trials in Jilin, Hunan and Guangdong during two years showed that the half-life of thiaclopdd in rice soil was 0.1 -0.5 d when application concentration was 315 g/hm^2. Under the dose condition with effective components of 315 and 210 g/hm^2, when insecticide was sprayed for 2 -3 times, the final residue in rice husk was lower than 7.830 mg/kg, the final residue in brown rice was less than 0.1 mg/kg. [ Conclusion] Take multiple factors into consideration, according to the recommended application dose of 210 g/hm^2, MRL value of thiacloprid in rice could be tentatively ascertained as 0.1 mg/kg, the preharvest interval was 7 d. aDolication frequencv was no more than two times.[ Objective] Residue condition of thiacloprid in soil and rice was studied.
