Determination of pre-harvest interval for fenvalerate and acephate in tomato and yard long bean using Gas Chromatography

The study was carried out to detect and quantify the left over residue of fenvalerate acephate in tomato yard long bean using Gas Chromatography coupled with Flame Thermionic Detector. Four supervised field trials were undertaken sprayed prescribed dose at rate 1mL/L water 2g/L water. samples collected 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14 15 days after spray (DAS). detected up 11 DAS all quantities above Maximum Residue Limit (MRL) set by European Union. No 12 bean. 13 bean, which EU-MRL 9 Fenvalerate contained 0.076-0.008 mg/kg 0.049-0.021 below 10 EU-MRL. So, case pre-harvest interval (PHI) determined for it Asian Australas. J. Food Saf.
