Online published on 8 January, 2020. Abstract Dissipation of chlorantraniliprole residues on tomato and brinjal fruits and cropped soil is reported by high performance liquid chromatography and confirmed by liquid chromatograph-mass spectrometer. The average initial deposits of chlorantraniliprole (18.5 SC) were 0.03 and 0.04 mg kg−1 in tomato which dissipated to below the maximum residue limit(0.03 mg kg−1) after 1 and 3 d after application of chlorantraniliprole @ 30 and 60 g a.i. ha−1 respectively. In case of brinjal crop, the initial deposits were 0.19 and 0.40 mg kg−1 after its application @ 40 and 80 g a.i. ha−1 respectively, which dissipated to below the limit of quantification (0.03 mg kg−1) after 7 d of spray. At 30 and 40 g a.i. ha−1 also, it proved effective in managing the damage caused by fruit borers in tomato and brinjal crops respectively.
