Residual Dynamics of Azoxystrobin in Strawberry and Soil
摘要
Abstract
Field trial and gas chromatography were carried out to study residual decline and final residues of azoxystrobin in the strawberry and soil.The results showed that when the added concentration of azoxystrobin ranged from 0.05 mg· kg-1 to 1.0 mg· kg-1,the recoveries changed from 97.16％ to 99.78％,and the coefficients of variation varied from 1.89％ to 3.67％.Meanwhile,the limit determination of azoxystrobin was 0.02 mg·kg-1.The half-lives of azoxystrobin was 3.66 days to 3.96 days in strawberry and 6.31 days to 8.79 days in soil,respectively.The final residue of azoxystrobin(250 g· L-1) SC was 0.17 mg·kg-1 to 0.20 mg·kg-1 when used in strawberry with the frequency of administration was not more than 3 times,interval of 7 days,and it was less than 1.0 mg· kg-1 that the Maximum Residue Limits(MRL)of the U.S.,Europe,Japan and other countries.关键词
