Abstract In order to formulate the standards for safe application of chlorpyrifos in celery under greenhouse conditions,penetrate,residual dynamics and the final residue in celery was conducted to investigate the residual dynamics of chlorpyrifos in celery.The results showed that chlorpyrifos could penetrate into celery,the penetrative quantity was 25 %-40 % of the total after application 1-7 day,the half-life of chlorpyrifos in celery was 9.90 days,the residue in celery was correlative to the application dosage and...
