Risk mitigation methods for different pesticides on Indian bean for food safety

Abstract

Objective: To evaluate the decontamination methods for the removal of pesticide residues on Indian bean for food safety.Material and Methods: Evaluation of effectiveness of decontamination methods were carried out by collecting zero-day samples from each treatment wise after spray and made into many sets at four replications. One set of sample from each treatment was analyzed for initial deposits of the pesticide and remaining sets of samples of zero day from each treatment were subjected to various decontamination methods separately and these samples were analyzed for residues through validated method.Results: The highest removal of all insecticides from green pods of field bean were obtained from the treatment Formula 1 (4% Acetic Acid + 0.1% NAHCO3 + 1 Lemon) ranging from 67.60 to 74.90 per cent followed by 2% salt solution in chlorantraniliprole 20% SC @ 30 g a.i ha-1, bifenthrin 10% EC @ 812 g a.i ha-1 profenophos 50% EC @ 400 g a.i ha-1, lambda cyhalothrin 5% SC @ 15.63 g a.i ha-1, beta cyfluthrin (Solomon 300 OD) @ 30 g a.i ha-1 while, 0.1% baking soda solution was found more effective than 2% salt solution for fipronil 5% SC @ 500 g a.i ha-1, flubendiamide 480% SC @ 60 g a.i ha-1 imidacloprid (Solomon 300 OD) @ 30 g a.i ha-1 and least removal of all insecticides from green pods of field bean was recorded from tap water wash which ranged from 11.39 to 29.64 per cent.Conclusion: Formula 1 (4% Acetic Acid + 0.1% NAHCO3 + 1 Lemon) decontamination process can be practiced as a house hold process which proves best practice in removal of pesticide residues on Indian bean surface towards food safety and better human health.
