摘要

Chlorfluazuron residues were determined in the peaches that were sprayed at dosage (a.i. 0.0167 kg 10a(-1)), using an analytical method that was validated as follows; r (2) = 0.9999, 0.02 mg kg(-1) (LOQ) and 87.8-93.6% (recovery). The residues from all samples were lower than the MRL (0.5 mg kg(-1), Korea). A maximum 0.27 mg kg(-1) of chlorfluazuron was detected in the samples applied at 6 days before harvest. The results signify that the 10% SC product would be used safely as an insecticide if it is applied two or three times onto peaches, with applications given until 6 days prior to harvest.
