The residual dynamics of flumioxazin in soil and soybean were determined with HPLC, using a Zorbax SIL column and methylene dichloride-methanol (99.5:0.5, V/V) as mobile phase. A method for pretreatment of samples and analysis was established. Recoveries of flumioxazin in soil, green soybean and soybean were 84.82%-85.63%, 88.79%-94.00% and 93.70%-94.48%, respectively. Flumioxazin degrades relatively slowly and its half-life in soil was 10.0-10.5 days, but in the soil, green soybean and soybean residual flumioxazin was not detected. The results showed that the residual pollution of flumioxazin is negligible, so the application of flumioxazin is safe for the soil and soybean.
