【Objective】 To establish a detection method of bifenthrin,and to study the residue and degradation dynamics of bifenthrin in the form of 1% bifenthrin·clothianidin granules in cabbage and soil. 【Method】Field experiments were conducted in Guangzhou of Guangdong，Nanning of Guangxi and Qianjiang of Hubei．Bifenthrin was added at three levels of 0.01，0.10，0.50 mg·kg^-1in the range from 0.01 to 1.00 mg·kg^-1. Bifenthrin was extracted from cabbage and soil using ultrasonic-assisted acetonitrile extraction，cleaned up using a florisil solid phase extraction column，then detected by GC with ECD detector, and quantified by external standard method．【Result】The average recovery rates of bifenthrin in cabbage were 83.64 %-96.44% with 3.26%-7.24%RSD，and the average recovery rates in soil were 86.76%-90.09%with 2.17%-4.94%RSD. The half-life of bifenthrin in soil was 6.77-13.51 d.No bifenthrin residue was detected in cabbage at harvest.【Conclusion】Bifenthrin is an easily degradable pesticide. Using 1% bifenthrin·clothianidin granules as pesticide is safe and recommended.
