Dissipation and Residues of Mandipropamid in Grape Using QuEChERS Methodology and HPLC-DAD

الملخص EN

The HPLC method for determination of mandipropamid residues and its dissipation in grape was investigated.

The mean recoveries of the analytical method were 98–102%.

The samples were collected within 2 weeks after pesticide application, and the pesticide residues were extracted by an optimized QuEChERS method.

Mandipropamid dissipated rapidly with half-life 2.20 days in grape.

According to maximum residue limit (MRL) the preharvest interval (PHI) of mandipropamid on grape was 4 days, after the last treatment.
