A simple and inexpensive technique for analysis of oxadiazon (5-tert-butyl-3-(2,4-dichloro-5-isopropoxyphenyl)-1,3,4,-oxadiazol-2(3H)-=one) residues in thatch and soil involving solid-phase extraction/purification and final gas-liquid chromatographic determination with nitrogen-phosphorus specific detection has been developed. The method, sensitive to 0.08ppm for thatch and 0.04ppm for soil, significantly reduces the use of organic solvents and labor, and allows simultaneous analysis of multiple samples.
