Abstract
AbstractThe study was carried out to determine the dissipation kinetics, persistence, and dietary risk assessment of tetraniliprole. Three applications of tetraniliprole were given at 50.00 g a.i./hac (X) and 62.50 g a.i/hac (1.25X) on chilli and brinjal at the fruiting stage. The recoveries in all the matrices were within the acceptable range of 70%–120%. The initial residues of tetraniliprole on chilli fruits were 0.379 and 0.593 μg/g and on brinjal fruits, the residues were 0.559 and 0.916 μg/g at 50.00 and 62.50 g a.i./ha, respectively. In red chilli, chilli field soil, and brinjal field soil the residues were below the limit of quantitation. The tetraniliprole follows first‐order dissipation kinetics with the half‐life (RL50) 1.58 and 1.99 days in chilli and 1.42 and 1.79 days in brinjal at X and 1.25X doses. In chilli, 9.89 and 12.11 days whereas, in brinjal, 10.75 and 13.25 days were recommended for harvesting the crops after the last application of tetraniliprole at X and 1.25 X doses, respectively. The hazard quotient values in chilli and brinjal for both males and females were below 1 indicating that the use of tetraniliprole does not cause any health risk to the consumers.
