Sonar® PR is designed for aquatic weed programs where steady performance and reliable concentration matter. Its pellet formulation gives managers a practical way to plan treatments across challenging freshwater sites where water movement or dilution can make control more difficult.

Sonar® PR provides a moderate upfront release of active ingredient while helping sustain Sonar® concentration after application. This makes it a useful option for programs that require continued exposure, careful timing, and confidence in treatment performance. For challenging aquatic weed programs, Sonar® PR helps managers balance release, exposure, and treatment timing with greater confidence.

• Systemic or full control of target plants
• Predictable Sonar release in a pellet formulation
• Maintains concentration after initial application
• Supports sites with dilution or flow
