摘　　要：[ Objective ] The paper was to study the residue dynamics of mancozeb in Capsicum annuum Linn and soil. [ Method ] Field spraying test and indoor analysis were carried out in three places of Changsha, Guangzhou and Beijing City during 2008 -2009 to study the digestion dynamics and the final residue of man- cozeb in C. annuum and soil, and gas chromatography was used for quantitative analysis. [ Result]The average recovery rates of mancozeb in C. annuum and soil were 86.59%-93.03% and 92.57%-95.14%, respectively. Mancozeb had rapid digestion in C. annuum and soft with the half-life of 2.29 -4.65 and 4.01 - 4.65 d, respectively. When metalaxyl-M,mancozeb water dispersible granule was sprayed in C. annuum according to the recommend dose （ spraying for no more than three times with the spraying interval of 5 d）, the final residue of maneozeb in C. annuum collected in the third day after the last spraying was less than 2 mg/kg.[ Objective ] The paper was to study the residue dynamics of mancozeb in Capsicum annuum Linn and soil.
