| 초록 | The present greenhouse experiment was carried out to study the residues of sulfoxaflor in spinach and Korean cabbage under different pre-harvest application regimes. After 2 times application of with 1 week interval in that day of harvest (0), 3, 7, 14 and 21 days before harvest, and the residue of pesticides was investigated by LC-MS/MS. Matrix-matched calibration curves for sulfoxaflor in both spinach and Korean cabbage yielded good linearity (R2 ≥ 0.9995). The biological half-lives of sulfoxaflor in spinach and Korean cabbage deduced from first order forms of decline (C=3.2539e-0.179t in spinach and C=1.2432e-0.196t in Korean cabbage) were 3.87 and 3.54 days, respectively. Pre-harvest residues of sulfoxaflor in spinach at 10-3 days (2.16 mg/kg) and 7-0 days (2.97 mg/kg) were above the EU-MRL (2.0 mg/kg), but within the MFDS value of 3.0 mg/kg. In Korean cabbage, residues at 10-3 days (0.74 mg/kg) and 7-0 days (1.17 mg/kg) were above the MFDS value of 0.3 mg/kg, though below the EU-MRL (6.0 mg/kg). Based on field incurred residues, it’s safe to apply sulfoxaflor to spinach as per MFDS regulation and Korean cabbage at 21-14 or 14-7 days before harvest as per EU regulation. | ||
