用气相色谱法测定了氟氯菊酯(天王星)在棉花叶片、棉籽和土壤中的消解动态及最终残留量。结果表明,在本地区特有的气候环境条件下,氟氯菊酯在棉叶和棉田土壤中消解速度较快,其半衰期分别为 8.7 d和 11.8 d。最终残留量的测定结果说明,氟氯菊酯在棉籽中无残留。

The dissipation and residues of biphenthrin in soil, cotton leaves and seed were determined by Gas Chromatography. It has been shown that under specific environment and climate in the investigated area, the amounts of biphenthrin in cotton leaves and soil were dissipated rapidly. The half- lives of dissipation were found to be 8.7 days and 11.8 days, respectively. The final residues of the insecticide remained in cotton seeds were discovered to be not detectable.
