Thiophanate-methyl is an effective fungicide on several food crops. In the present study, dissipation of residue levels of thiophanate-methyl in apple and strawberry fruits under open field conditions were studied using high performance liquid chromatography with diode array detection (HPLC-DAD).The extraction and clean-up were conducted by QuEChERS method. The limit of quantitation and detection were 0.01 and 0.003 mg/kg, respectively. The results suggest that the thiophanatemethyl dissipation curves followed the first order kinetics and its half-life values were (1.01) and (1.26) days for apple and strawberry, respectively. The residues in apple and strawberry were below the codex maximum residue limit (MRL) (0.5 and 0.1 mg/kg) after 8 and 4 days of the application, respectively.
