Sonar AS Aquatic Herbicide is a professional-grade systemic aquatic herbicide trusted for long-term selective control of invasive aquatic weeds in lakes, ponds, reservoirs, irrigation canals, and other freshwater systems. Powered by fluridone, Sonar AS provides season-long or year-long control of many troublesome aquatic weeds with a single application, making it one of the most effective and economical aquatic vegetation management solutions available. Widely recognized as the industry standard for duckweed control, Sonar AS slowly disrupts carotenoid production in susceptible aquatic plants, leading to gradual bleaching and plant death while minimizing oxygen depletion and water quality disruption often associated with rapid vegetation collapse. Sonar is highly effective on duckweed, hydrilla, coontail, Eurasian watermilfoil, bladderwort, and other labeled submerged and floating aquatic weeds. Unlike many aquatic herbicides, Sonar AS has minimal restrictions on recreational water use following application. Swimming, fishing, and livestock watering may continue according to label directions, though irrigation restrictions may apply for certain sites and crops. Developed by SePRO, a recognized leader in aquatic plant management, Sonar AS has been trusted by professional aquatic applicators and lake managers throughout the United States for decades.
