Rapeseed stalk as a kind of vegetables is popular with Chinese residents.However,pesticide resi-dues in rapeseed stalks were not well monitored.The aim of this study was to evaluate the current situation of pesti-cide residues in rapeseed stalk from four provinces in south China,and to provide a scientific basis for the develop-ment of related industries and food safety.A total of 38 pesticide residues were detected in 86 samples collected from 4 provinces including Hubei,Jiangxi,Sichuan and Yunnan in the period of January to March 2022.The types of pesticides include insecticides,fungicides,herbicides and plant growth regulators.The test results were judged according to the Chinese National Standard GB/T 2763-2021"National food safety standard-Maximum residue limits for pesticides in Food"and EU pesticide residue regulations.A total of 50%of the samples contained pesti-cide residues.The detected compounds were procymidone,carbendazim,paclobutrazol,quizalofop-P-ethyl and benazolin-ethyl.Although a high incidence of pesticide detection was observed,the levels of pesticides detected were low,which indicating a low risk to food safety.
