  • Applications

    In agriculture, particularly in rice production, bispyribac-sodium is a selective post-emergence herbicide used to control annual grasses and some broadleaf weeds; it inhibits the ALS (acetolactate synthase) enzyme and exhibits systemic movement within treated plants, contributing to effective weed control in rice; it is typically formulated for foliar spray in paddy fields and is commonly integrated into weed-management programs with other herbicides.
