Abstract: A gas chromatographic analytical method for the determination of tricyclazole residues in rice, soil and water samples was described. Tricyclazole was extracted from soil, brown rice and rice husk by refluxing with ethyl acetate-acetone (80:20, V/V), from rice leaf with ethyl acetate and from water by partitioning into dichloromethane. The extract of soil and rice was cleaned up using coagulation. The compound was detected and measured by gas chromatography with flame photometric detection (S-mode). Spiked with tricyclazole, the recoveries averaged 95.4±4.2%(X±Sx%), for soil with additive concentration ranging from 0.10-5.00μg/g, 97.3±5.3% for water with that rangeing from 0.10-1.00 μg/ml and 95.4±4.4%, 96.2±9.1% and 95.0±4.4% for rice leaf, brown rice and rice husk with that ranging from 0.10-1.00μg/g, respectively.
