摘要
按沙田柚园上桔实雷痪蚊的防治期适期喷施４０％辛硫磷乳油（３ ．７５ｋｇ／ｈｍ～２），其在不同果园土壤中的原始沉积量为８１ ．６５～１３２．９６ｋｇ／ｈｍ～２，半衰期为２．７～４．５ｄ，药后７ｄ各处理点辛硫磷的消解率均在９０％以上。
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.
