Bispyribac

Bispyribac (CAS 125401-75-4) is a pyrimidinyloxybenzoic acid herbicide used in rice cultivation to control a broad spectrum of weeds.

Where is Bispyribac used?

• Rice: selective post-emergence control of grassy and broadleaf weeds in transplanted and direct-seeded paddy
• Paddy and upland rice systems: single-active and combination herbicide products
• Residue analysis and regulatory submission workflows: reference standard
• It inhibits acetolactate synthase (ALS) to suppress barnyardgrass and sedges.

Good to know: Bispyribac sodium is the commercially dominant salt form and primary commercial form. Not to be confused with other ALS-inhibiting herbicides.
