Abstract: Persistence studies of bifenthrin 10% EC and lambda cyhalothrin 5% EC in / on green chilli was undertaken by following two foliar applications at recommended dose (50 g a.i./ha; 15 g a.i./ha) at fruiting stage of the crop. The residues of bifenthrin and lambda cyhalothrin dissipated to below limit of quantification (LOQ) of 0.05 mg/kg on 7^th and 10^th day with half-life of 2.89 and 5.01 days respectively. Considering this, waiting period of seven to ten days can be suggested for bifenthrin and lambda cyhalothrin with reduced risk of insecticide residues in green chilli.
