摘　　要：本试验对棉田样品中IKI—7899的残留量测定作了改进。由对农药添加样品的测定结果表明,IKI—7899在棉籽、棉叶和土壤中的添加回收率分别为88.3％,83.9％和85.9％;最小检出浓度分别为0.005ppm、0.005ppm和0.0025ppm;对实际样品的测定表明,本法能满足IKI—7899在棉花上残留动态试验的要求。The analytical method for IKI-7899 in cotton field has been improved in this experiment. The results obtained from analysis of the sample added with the pesticides showed that the average recovery rates for IKI-7899 in cotton seed, leaf and soils were 88.3%, 83.9% and 85.9%respectively, and the detection limits were 0.005 ppm, 0.005 ppm and 0.0025 ppm respectively. The improved method satisfies the requirements for the dynamic experiments of IKI-7899 residue in cotton field.
