residual analysis and half-life time of imidazole fungicide prochloraz in soils (silty clay) were investigated by gas chromatography equipped electron capture detector (GC-ECD). The soil samples were extracted acetone/hexane(1:1) solvent and analyzed after separated by LC-NH2 Sep-Pak solid column. Linear sensitivity of standard calibration curve was Y = 268.8600X + 0.0664, R2 = 0.9998 between 0.05∼1.00 ng. The detection limit was 0.02 ㎎/L and the average recoveries were 94.5∼97.3% from the standard additional experiments with 0.10 and 0.40 ㎎/L. The half-life time was 24.4 days in room laboratory and 7.6 days in the field test soil.
