This study was conducted to the amount of pesticide residue in 21 different kinds of 100commercial flowering teas. Multi-residue analyses of 203 pesticides was performed using the GC-ECD, GC-NPD, GC-MSD, and LC-MS/MS. Pesticide residues were detected in 4 samples (4%) of which 4 samples(4%) violated the maximum residue limits. 4 samples violating the limit were all imported teas. Pesticidesdetected were chlorpyrifos, flufenoxuron, lufenuron, pyrimethanil and methoxyfenozide. These results indicatethe need of continuous monitoring of pesticide residue needs for safety of flowering teas. Key words Flowering teas, Pesticides, MRLs          , ,    .
