| 摘 要： | 本文用气相色谱电子捕获检测器，通过田间试验研究杀虫单在水稻和土壤中最终残留。结果表明按常规用药剂量和高剂量施于水稻田后，杀虫单最终残留量表现为：稻壳〉稻田土壤〉植株〉糙米。建议杀虫单在水稻合理使用：按混剂用药剂量600、900g a．i．／hm^2（其中杀虫单为180、270g a．i．／hm^2）在水稻生长期施药，施药3次，2次施药的间隔时间为14d，安全间隔期至少为14d。收获时杀虫单在稻田土壤、稻植株、稻壳、糙米中的残留量均〈0．50mg／kg。

| Abstract: | Residues of monosultap in rice and soil were determined by gas chromatography with electron capture detector. The results showed that the final residues of monosuhap were as in paddy〉soil〉stalk〉rice.The final residues were all less than 0.50mg/kg in paddy, soil, stalk and rice with the application dosage of 180-270g（a.i.）/hm2, 3 times during the growth period while the interval time were 14d. It was recommended that the safety interval should be at least 14d befor harvest. |
