WINSTA 30% WP is a modern selective post-emergence herbicide formulated as a Wettable Powder (WP), combining Bensulfuron and Bispyribac-Sodium for highly effective control of a wide range of grassy, broadleaf, and sedge weeds in rice.

Mode of Action:

Bensulfuron: A sulfonylurea herbicide that inhibits the ALS (Acetolactate Synthase) enzyme, stopping cell division and growth in susceptible weeds.

Bispyribac-Sodium: A pyrimidinyl carboxy herbicide that also inhibits the ALS enzyme, providing strong control of grasses and sedges.

 Together, they provide dual systemic action, ensuring broad-spectrum weed control with long-lasting effectiveness.

• Post-emergence flexibility
• Systemic action for complete weed control
• Highly effective in rice ecosystems
• Reduces weed competition at critical stages
