AB  - 20% commercial suspension emulsion (SE) of (8% tetraconazole + 12% 
      kresoxim-methyl), as a pre-registered product in China, was firstly investigated 
      under Chinese greenhouse-field conditions. A MWCNTs-based QuEChERS method for 
      simultaneous determination of tetraconazole and kresoxim-methyl in strawberry was 
      developed and validated via RRLC-QqQ-MS/MS. On basis of this method, the 
      dissipation behaviours, residue distributions and dietary risk probability of 
      these fungicides in strawberry were further investigated for food safety. The 
      dissipations of tetraconazole and kresoxim-methyl followed first-order kinetics 
      with the half-lives of 8.0-18.2 days. The highest residues (HRs) of these 
      fungicides in the supervised trials at the pre-harvest interval (PHI, 3 days) 
      were below 0.8970mgkg(-1). The total national estimated daily intake (NEDI) of 
      tetraconazole and kresoxim-methy in strawberry at the PHI 3day was 0.2784mg and 
      0.4031mg, respectively, based on Chinese dietary pattern and terminal residue 
      distributions under good agricultural practices (GAP) conditions. The risk 
      quotients (RQs) of tetraconazole and kresoxim-methy at PHI 3 days were below 
      82.7% and 1.6%, respectively, showing that the evaluated strawberry exhibited an 
      acceptably low dietary risk to consumers. The current study could not only guide 
      reasonable usage of the formulation, but also facilitate the setting of maximum 
      residue limits (MRLs) of tetraconazole in strawberry.
