Dissipation dynamics and risk assessment of carbosulfan in brinjal (Solanum melongena L.) fruits

Abstract

The present study was conducted to investigate the persistence behavior and dissipation dynamics of carbosulfan in brinjal fruits to assess its risk in consuming the fruits. The results revealed that the residues were 0.05, 0.12 and 0.27 μg g-1 at 15 DAT at the first harvest of the fruits after three rounds of spraying when applied at 250, 500 and 1000 g a.i.ha-1 respectively. However, the residues were below detectable limit at all the levels of application at the third harvest of the produce. The residues were below the maximum permissible residue limit (MRL) of 0.1 μg g-1 at the recommended dose of 250 g a.i. ha-1 even at the first harvest itself making it as a suitable insecticide for managing brinjal pests without any risk.
