Bispyribac sodium is a systemic herbicide commonly used to control grassy and broadleaf weeds in rice paddies and other aquatic and terrestrial crops such as wheat, barley, and soybeans.
It belongs to the pyrimidinyl carboxy herbicide group and works by inhibiting the enzyme acetolactate synthase (ALS), which is essential for the biosynthesis of branched-chain amino acids in susceptible weeds, leading to their death.
Bispyribac sodium is valued for its efficacy, low application rates, and selectivity against grassy weeds while being relatively safe for broadleaf crops.
However, proper application techniques and stewardship practices are essential to minimize the risk of crop injury and environmental contamination.
