A field experiment was conducted at Main Sugarcane Research Station, Navsari Agricultural University, Navsari to study the dissipation behaviour of fipronil and its metabolites in sugarcane grown soil. The fipronil 0.3 GR was applied at standard and double dose i.e. 100 and 200 g ai ha-1 in gross plot when sugarcane crop was four month old. The soil sampling was done at 0 (2 hrs.), 1, 3, 5, 10, 20, 30, 60 and90 days after application of fipronil. In method verification, acetonitrile based extraction and dispersive clean-up approach adopted to quantify the residues of fipronil and its metabolites with gas chromatography (GC-ECD) from soil was accurate, precise and sensitive enough. Persistence study indicated that residues of fipronil progressively dissipated and reached BQL (
