Along with Sonar SRP, Sonar A.S. (liquid in gallon, quart and pint containers) is one of the two original formulations of Sonar Aquatic Herbicide. While each Sonar formulation provides applicators an abundance of options when seeking to control nuisance aquatic vegetation in a variety of treatment situations, Sonar A.S. is available for immediate uptake into the target plants. Sonar A.S. provides the most efficient concentration level and is the ideal choice in waterbodies with minimal water flow and when targeting strands of emersed vegetation.
Sonar Aquatic Herbicide selectivity is dependent upon dosage, time of year, stage of growth, method of application and water movement. Please see the Sonar label for an outline of vascular aquatic plants controlled, partially controlled and not controlled by Sonar. Algae (chara, nitella, filamentous species) are not controlled by Sonar. Consult a SePRO Aquatic Specialist prior to application of Sonar Aquatic Herbicide to determine your target plants' susceptibility.
