Easy to apply with precise dosage control, reducing the mess and hassle of liquid application, making treatment straightforward for users of all experience levels.
Long-lasting Effects
Provides prolonged control of invasive aquatic vegetation, minimizing the frequency of treatments needed, ultimately saving time and money for pond management.
