Abstract
The study was conducted to analyze difenoconazole, dimethoate, chlorantraniliprole,
pymetrozine residues on brinjal fruits collected from different fields and markets of
Bangladesh during November 2021. The collected samples were analyzed using
modified Quick, Easy, Cheap, Effective, Rugged and Safe (QuEChERS) extraction
technique and LC-MS/MS for the determination of pesticide residues in 50 field
samples and 50 market samples of brinjal. Among the 50 analyzed field samples,
pymetrozine was detected in 4 samples (8%), dimethaote was detected in 10 samples
(20%), difenoconazole was detected in 6 samples (12%) and chlorantraniliprole was
detected in 7 samples (14%). In 50 market samples, pymetrozine was detected in 2
samples (4%), dimethaote was detected in 5 samples (10%), difenoconazole was
detected in 4 samples (8%) and chlorantraniliprole was detected in 8 samples (16%).
All of the samples detected with pymetrozine, dimethaote, difenoconazole residues
has residue above Maximum Residue Level (MRL).
