Sonar® H4C is designed for aquatic weed management programs where pellet placement and treatment-area coverage are critical. Its high-coverage pellet formulation helps applicators place more Sonar contact points across the treatment area, improving exposure to targeted aquatic weeds.

This makes Sonar® H4C a strong fit for spatially targeted programs, including hydrilla management and other submersed aquatic weed treatments where coverage, placement, and water movement are important planning factors.

• Systemic or full control of target plants
• High-coverage Sonar pellet formulation
• Maintains concentration after initial application

• Supports sites with high dilution or flow
