Abstract: Amaranth (Amaranthus tricolor L) is a major leafy vegetable extensively consumed in Kerala. Farmers have been using pesticide in a wide range to protect crop from pests. This resulted in high residues of pesticides on amaranth. A preliminary survey was conducted to monitor pesticide residues on amaranth. Among the insecticides using on amaranth organo phosphates and synthetic pyrethroid insecticides are major insecticides group. Here to evaluate efficiency of different decontaminating methods in removal of synthetic pyrethroid pesticide residues from amaranth plants were sprayed with different SP insecticides viz., bifenthrin 10% EC, cypermethrin 25% EC, fenvalerate 20% EC and Lambda cyhalothrin 5% EC were subjected for decontamination methods viz., washing, 2% common salt, 2% vinegar, 1% turmeric, 2% tamarind, 1% veggie wash (produced by Kerala Agricultural university, Vellayani) and cooking. The residues in control and processed plants were estimated by using Gas Chromatograph equipped with Electron Capture Detector. Dipping in 2% tamarind, 1% veggie wash for 10 minutes followed by three further washings + cooking and 2% common salt were found to be effective in removal of SP insecticide residues at the average of 67%, 64% and 63%. This study helped to standardize simple and effective method in removal of most commonly used synthetic pyrethroid insecticide’s residues in amaranth.
