This study was investigated to determine the residual amounts of bifenthrin which is used to control Spodoptera litura using gas-liquid chromatography (GLC) with electron capture detector (ECD). Recoveries obtained from two concentrations were 95.33% and 97.82%, respectively. The residual amounts of bifenthrin in the chwinamul (Aster scaber) ranged from 1.42 to 3.08 mg kg-1. Because the maximum residue limits (MRL) of bifenthrin in the chwinamul (Aster scaber) was 1.0 mg kg-1, it can be proposed for these chemicals to apply up to 3 times before 14 days of harvest in Korea.
