为了解灭多威施用后在棉田中的残留降解行为，全面准确评价灭多威的生态环境安全性，指导其科学合理施用，笔者通过动态及残留实验．研究了灭多威在棉花及其土壤上的动态降解及最终残留行为。结果表明：施药3d后，灭多威在棉田土壤和棉叶中的消解率均大于50％：施药28d后，灭多威在棉田土壤和棉叶中的消解率均在90％以上。灭多威在湖南长沙的棉田土壤和棉叶中的半衰期为11．39d和10．04d；在河北石家庄的棉田土壤和棉叶中的半衰期为9．99d和8．94d。灭多威在棉田土壤中的最终残留量均低于0．50mg／kg；在棉叶中的最终残留量均低于0．40mg／kg：在棉籽中的最终残留量均低于最小检出量0．02mg／kg...

In order to find out the residual degradation of Methomyl after it had been used in cotton field, assess completely and correctly the bio-environmental safety of Methomyl, and guide how to use it in scientific and rational way. This paper research dynamic degradation and final residual behavior in cotton and soil of Methomyl, by means of dynamic and residual experiment. The results indicated that the degradation rates in cotton soil and cotton leaves both exceeded 50%, after Methomyl had been used for 3 days; and the degradation rates exceeded 90% after Methomyl had been used for 28 days. The ...
