Dynamic Study on Residual Digestion of Dimethomorph and Ametoctradin in Pepper and Soil
摘要
Abstract
Residue dynamics of dimethomorph and ametoctradin in pepper and soil were studied to evaluate their using safety.A field trial was performed, and the target pesticides were determined by UPLC-MS/MS. The decline rules of dimethomorph and ametoctradin in pepper and soil followed the first order chemical reactions dynamics equation, and their half-lives were 1.8 ~4.6 d and 7.4~23.3 d in pepper and 6.6~12.8 d and 3.6~7.0 d in soil respectively. The final residues measured were <0.04~0.58 mg·kg-1 and 0.06~0.27 mg·kg-1 in pepper, <0.01~0.98 mg·kg-1 and 0.01~0.18 mg·kg-1 in soil. The residues of dimethomorph and ametoctradin detected in pepper and soil were all less than the maximum residue limit of GB/T 2763-2016. Correct use under specification would not cause pollution of residues in pepper and soil.关键词
