Product Overview

Sonar Q delivers Sonar's active ingredient (a.i. fluridone) on a fast-releasing, easy-to-use pellet, allowing more accurate placement and targeted contact with undesired plants. Rapid pellet expansion allows the product to remain buoyant on sandy or firm bottoms, avoiding complications from the organic tie-up.

Quick, Accurate Control

Formulated as a 5% active ingredient on a 1/8-inch diameter granular pellet, Sonar Q quickly expands for an accelerated release into the water column, providing better control in ponds with muck sediments and high organic content.  When used in ponds, Sonar Q releases a higher amount of active ingredient into the plant than other Sonar pellet formulations in a shorter amount of time.

Innovative Release Process

The Sonar Q pellet begins the degradation process immediately upon contact with the water.  Once submerged the Sonar Q pellet swells and expands, transforming the pellet into a buoyant composition that will rest on top of soft muck bottom sediments.  Sonar Q has the efficient concentration level of a liquid but provides for more accurate placement. The pellets will land where they are thrown, eliminating overspray onto sensitive shoreline vegetation like lawns.

Sonar Formulations Offer Choices

Our abundance of Sonar formulations allows us to provide applicators the options they need for controlling nuisance aquatic vegetation in a variety of treatment situations.  Please see the Sonar Q 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.  The selectivity of Sonar Q is dependent upon dosage, time of year, stage of growth, the method of application, and water movement.
