Residue and Degradation Dynamic of Buprofezin in Citrus and Soil
摘要
Abstract
[ Objective ] The paper was to detect the residue of buprofezin in citrus and soil. [ Method ] Gas chromatography (GC) method was used to measure the residue of buprofezin in citrus and soil. [ Result ] The average recovery rate of buprofezin in entire citrus fruit was 96. 17% -97.38%, and the variation coefficient was 6.10% - 9.07%; the average recovery rate in pulp was 95.24% - 105.46%, and the variation coefficient was 3.30% - 6.01% ;the average recovery rate in peel was 88.76% - 93.64% ,and the variation coefficient was 5.12% - 6.27%;the average recovery rate in soil was 97.79% - 104.3% ,and the variation coefficient was 2.45% - 9.21%. The degradation dynamics and the final residue results of buprofezin in citrus and soil showed that the degradation half-lives in citrus in Changsha (Hunan),Hangzhou (Zhejiang) and Guiyang (Guizhou) were 7.65,7.64 and 8.40 d ,and the degradation half-lives in soil in three places were 13.75,9.97 and 10.18 d,respectively. [ Conclusion ] When 25% buprofezin SC watered agent were sprayed in citrus fruits for 2 - 3 times according to the recommended dose of 166.7 -250.0 mg/L,the safe period of buprofezin in citrus could be set as 14 d.关键词
