半衰期

Flumioxazin degrades relative ly slowly and its half- life in soil was 10.0-10.5 days, but in the soil, green soybean and so ybean residual flumioxazin was not detected. The results showed that the re sidu al pollution of flumioxazin is negligible, so the application of flumioxazin is safe for the soil and soybean.

速收在土壤中的半衰期(t1／2)为10.0～10.5 d，降解速度较慢，但在收获期的土壤、青豆(用药后80～85 d)和大豆籽粒中均未检出，说明其残留污染性很小，可以在大豆田安全使用。
