The consumers are very much concerned about food safety. To ensure safe for the consumers, it is essential to follow pre harvest interval (PHI) of pesticides. Therefore, in order ascertain pre-harvest fenitrothion and diazinon hyacinth bean environmental conditions Bangladesh, this study was started. chosen organophosphorus insecticides (fenitrothion diazinon) were sprayed with recommended dose (1.5 ml/L water) a field trial at Entomology Division BARI, Gazipur. At 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 12 days after spray (DAS), samples taken. Gas chromatography (GC) Flame Thermionic Detector (FTD) used quantify residues prepared using modified Quick, Easy, Cheap, Effective, Rugged Safe (QuEChERS) extraction method. Fenitrothion residue found up 8 DAS, 7 DAS (0.018 mg/Kg), level above MRL. 0.007 mg/kg, which below Pre-harvest determined no 9 DAS. Diazinon MRL (0.016 mg/Kg). as 10 found. Asian Australas. J.

The present study was conducted to determine the pre harvest interval of chlorpyrifos and quinalphos in hyacinth bean agro-climatic condition Bangladesh ensure safe food for consumers. A supervised field trial undertaken experimental Entomology Division BARI, Gazipur selected pesticides (chlorpyrifos quinalphos) were sprayed with recommended dose (1.5 ml/L water). samples collected at 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 12 days after spray (DAS). extracted cleaned up using modified Quick, Easy, Cheap, Effective, Rugged Safe (QuEChERS) extraction technique residues determined by Gas Chromatography (GC) coupled Flame Thermionic Detector (FTD). residue detected upto 8 DAS (0.027 mg/Kg) a level above EU-MRL, 9 DAS, no detected. So, PHI set DAS. On other hand, which EU-MRL (0.02 mg/kg). At remained 0.009 mg/Kg, below EU-MRL. Asian Australas. J. Food Saf. Secur. 2023, 7 (1), 47-55

The application of fipronil for the control insect pests different crops is increasing day by day. As a result, it inevitable to remain residues in treated crops. Therefore, an urgent need develop analytical method quantification fipronil. Keeping this view, study was initiated and optimize residue using Gas Chromatography triple quadrupole Mass Spectrometry (GC-MS/MS). A number experiments has been conducted select parent ion precusor based on these findings, determination GC-MS/MS developed. linearity developed very good 0.999. optimization MS/MS parameters done properly through direct injection 100 ug/L standard solution Asian Australas.
