Choose the Right Sonar* For Your Pond.
Three Unique Formulations
Dedicated to advancing the science of aquatic plant management, SePRO has conducted over six years of extensive research on product formulations,
release rates and pond sediment to discover how these three critical factors affect plant control.
As the culmination of this research, pond managers and owners now choose from two distinct formulations of Sonar,
the world's leading brand of aquatic herbicide for the selective, long-term control of undesirable aquatic vegetation.
Sonar RTU (Liquid)
Sonar RTU—our newest formulation for successful do-it-yourself weed control for ponds. Sonar RTU is a Ready-to-Use formula that controls most troublesome pondweeds including Duckweed. No mixing, no need for spray equipment or a boat—simply apply directly into the water from the shoreline.
Sonar A.S. (Liquid)
Sonar A.S. (Aqueous Solution) is the liquid formulation of Sonar available for immediate uptake into the target plants and is best in ponds with minimal water flow that have a mucky or high organic bottom.
Sonar Q (Pellets)
Sonar Q (Quick) is your best choice for season-long control of all pondweeds in ponds with sandy or firm bottoms.
If you have any questions about which Sonar formulation is right for you,
a SePRO Pond Advisor will gladly guide you through the entire Sonar treatment process including helping you determine which formulation will provide the most selective,
long-term control of undesirable aquatic vegetation in your pond.
