The study was conducted in the experimental field and Pesticide Analytical Laboratory of Entomology Division, Bangladesh Agricultural Research Institute (BARI), Gazipur during 2014-15 to evaluate the effect of different decontaminating solutions in the removal of organophosphorus insecticide residues in brinjal and chilli. Five insecticide viz. diazinon, malathion, fenitrothion, quinalphos and chloropyrifos formulation were sprayed in brinjal and chilli plant. Estimation of residues was done using Gas Chromatograph equipped with Flame Thermaionic Detector. The results indicated that dipping in 2 % salt water solution for 15 minutes followed by washing under tap water plus cooking was found to be more effective in reducing all pesticides tested when compared with other treatment solutions both in brinjal and chilli. This study facilitated to standardize simple cost effective approaches to eliminate harmful pesticide residues from brinjal and chilli which could be adept by home makers.
