The residue of thiabendazole in apple and soil were determined with HPLC.The samples were extracted with ethyl acetate followed by a simple clean-up procedure and determined wth HPLC-UV,The fortified recoveries of thiabendazole and CVs in apple and soil were 87.8%～99.8%and 0.4%～2.3%,respectively. Thiabendazole dissipated fast in apple and soil,with half-lives of 6.2～9.8d and 11.3～17.8d,respectively. The preharvest interval of thiabendazole in apple was 14d.
