Bispyribac Sodium is a systemic, selective herbicide used primarily in rice cultivation to control a wide spectrum of grass, sedge, and broadleaf weeds. It is effective as a post-emergence herbicide and is absorbed both through foliage and roots. It works by inhibiting acetolactate synthase (ALS), an enzyme crucial for amino acid biosynthesis in plants.
