| Abstract: | Phoxim (40% EC) was applied to the pomelo orchard soil for the control of citrus midge (Tesseliella citrifrugis Jiang) . Its original accumulation was 81.65 ~132.96 mg/kg in soil. And its half-life was 2.7 ~4.5 days. Results indicated that degradation of phoxim was rapid in soil. The residues decreased over 90% in 7 days treatment. |

| Keywords: | phoxim degradation dynamic half-life residue pomelo |
