Abstract: An experiment was conducted at the Instructional Farm of Post Graduate Institute, MPKV, Rahuri to determine the extent of reduction in pesticide residue levels in brinjal fruits through different household decontamination processes. Single application of insecticides viz., profenophos and triazophos was given at the fruit initiation stage with recommended dose by knapsack sprayer. After 2 hr of spraying, harvested brinjal fruits were subjected to five different processing methods viz. washing with tap water, washing with 2% salt solution, washing with 2% tamarind solution, boiling and cooking. Treated samples were analysed for insecticide residues by using validated QuEChERS method on Gas Chromatograph. The results revealed that all the treatments removed the residues of insecticides but, cooking brinjal fruits showed highest reduction in dislodging the residues of profenophos (90.97%) and triazophos (86.5%) from brinjal fruits.
