Residue Dynamics of Mancozeb in Chilli ( Capsicum annuum Linn) and Soil
摘要
Abstract
[Objective] The paper was to study the residue dynamics of mancozeb in chilli 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 degradation dynamics and the final residue of mancozeb in chilli and soil, and gas chromatography was used for quantitative analysis. [ Result ] The average recovery rates of mancozeb in chilli and soil were 86.59% -93.03% and 92.57% -95.14% .respectively. Mancozeb had rapid digestion in chilli and soil with the half-life of 2.29 -4. 65 and 4. 01 -4. 65 d, respectively. When metalaxyl-M · mancozeb WDG was used in chilli according to the recommend dosage (spraying for three times at most with the spraying interval of 5 d) ,3 d later after the last spraying,the final residue of mancozeb in chilli collected was less than 2 mg/kg. [ Conclusion ] The result provided basis for preparation of safety standards of mancozeb.关键词
