Sonar SRP Aquatic Herbicide (slow release pellets in 40 lb. pails) 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 SRP provides unique slow dissipation to offer an extended period of contact with the target plants. Sonar SRP is the ideal formulation to prevent dilution in rapid water movement and maintain the high degree of efficacy expected with the Sonar product line.
Sonar SRP 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.
