The solvent extraction and clean up processes for the gas chromatographic determination of muarimol pesticide residues in apples were investigated and examined the changes of residual concentration with the passage of time. The extracted pesticide with methanol were partitioned with dichloromethane after adding sodium chloride solution. The separated solutions were concentrated and transfered to the alumina column for clean up, and eluated with 1-chlorobutane : methanol solution. As a results their recovering for 0.200 and 1.00ppm muarimol spiked on apples have shown 79~95%. Residual amounts of nuarimol in apple was 0.0830ppm when the fungicide was treated eight times until 3 days before its harvest. It seems to be safely used when nuarimol is treated six times until 7 days before harvest of apple.
