Fate and behaviour of flupyrsulfuron-methyl in soil and aquatic systems

The environmental fate of [14C]flupyrsulfuron‐methyl, a sulfonylurea herbicide, was investigated in soil and aquatic systems. The major degradative pathways in both systems were contraction of the sulfonylurea bridge followed by intramolecular rearrangement (at pH>7) or sulfonylurea bridge hydrol...
