残留试验表明，用20％康福多浓可溶剂600ml／hm2喷施防治稻飞虱，在田水中原始沉积量为0．11～0．25mg／kg，半衰期为5．9～7．9 d；在土壤中原始沉积量为0．08～0．16mg／kg，半衰期为5．3～24．6 d；在茎叶上原始沉积量2．82～6．99mg／kg，半衰期为6．5～6．8 d。最终残留量试验，表明在水稻卷叶螟、稻飞虱发生期喷药2次，施药剂量为300～600ml／hm2，最后一次施药距收获期为7 d，在糙米中残留量均低于0．05mg／kg，在土壤和茎叶中的最终残留量分别小于0．083 mg／kg和0．822 mg／kg。

Imidacloprid 20 OSL was applied at 600 ml/hm2 for controlling rice planthopper.Its original accumulation was 0.11 - 0.25 mg/kg in water,0.08 - 0.16 mg/kg in soil and 2.82 - 6.99 mg/kg in fice stem and leaf. Its half-life was 5.9-7.9 d in water ,5.3-24.6 d in soil,and 6.5-6.8 d in rice stems and leaf. For controlling the rice planthopper, two applications of Imidacloprid 20 OSL at 300- 600 ml/hm2 for twice were made with an interval of 7 days between the last spray and harvest . The result showed the residue was < 0.05 mg/kg in rice , < 0.083 mg/kg in soil , < 0.822 mg/kg in stem and leaf.
