Residue of fipronil was studied on rice crop following three application of the product at 7 days interval @ 50 and 100 g ai ha^-1. The residues were estimated by HPLC equipped with UV detector at 280 nm wavelength. The limit of quantification was 0.001 μg g -1 for rice plant, grain and soil. Recoveries of fipronil at 0.01, 0.10 and 0.50 μg g^-1 fortifications were in the range of 80.00-87.00%, 81.00-89.80%, 87.00-91.40%, and 85.00-89.20% in rice straw, husk, grain and soil, respectively. Residues of fipronil were below maximum residue limit of 0.001 μg g^-1 at harvest in husk, grain and straw.
