Sonar Quick Release (Q) is SePRO’s newest Sonar* pellet formulation designed to deliver an accelerated release of the Sonar active ingredient. Faster than Sonar SRP and Sonar Precision Release* (PR) pellets, Sonar Quick Release provides a fast, yet measured release of Sonar into the waterbody providing even longer-lasting efficacious concentrations than Sonar A.S. liquid. Sonar Quick Release, with its unique release profile, and formulated on an easy-to-handle pellet, allows professional aquatic applicators to save time and labor costs when applying to multiple ponds. The rapid expansion of the Sonar Quick Release pellet, and accelerated release of Sonar herbicide, delivers more active ingredient for better nuisance aquatic plant control in ponds with high organic or muck sediments.
This pellet formulation is recommended for use in water bodies with sandy or rocky bottoms. Sonar Q accelerates the release of fluridone concentrations into the water column. Sonar Q provides a longer-lasting residual than liquid Sonar A.S., and still delivers an effective dose to targeted plants within the first day. The rapid pellet expansion allows the product to release fluriudone quicker while remaining buoyant on sandy or firm bottoms, avoiding complete organic tie-up. As Sonar Q is immediately carried to the bottom of the waterbody, Sonar’s active ingredient is less likely to be impacted by initial light degradation, preserving valuable fluridone parts per billion (ppb’s) for targeted plant control.

Direction For Use
This “ready-to-apply” pellet formulation allows you to place the Sonar exactly where desired. Apply Sonar Q at a rate of 20 pounds per acre at an average depth of 4′ – 6′ or 4 lbs. per acre-foot. Sonar Q makes water usable for recreation and helps provide an environment for bringing fish populations back into balance. Sonar usage won’t restrict swimming, fishing or drinking.
Sonar Q can be applied starting in early spring, at the first sign of weed growth.
Best control is obtained when water discharge can be stopped for thirty days or longer. Pond levels should be at or near normal water level when treated. Excessive outflow dilutes Sonar Q and reduces the chance of control. Outflow can be reduced by lowering pond level prior to treating with a siphon made from a rubber or PVC pipe.
The dose for the first Sonar Q treatment is normally 20 lbs. per surface-acre depending upon depth (see product label).
The labeled rate for Sonar Q should be split and applied in two applications about 10 – 14 days apart. For small ponds, application can be made from the bank. Spread pellets directly from container into the water. It is not necessary for Sonar Q to come into direct contact with the plants for effective control. If infestation is heavy, disperse thick mats in order to get the product directly into the water. Be sure to triple rinse the container and pour the rinse water back into the pond.
Plants should start turning white as control begins in 2 – 4 weeks. It may take 5 – 10 weeks for final results. This slow rate of control is beneficial as it greatly decreases the chance for a severe change in oxygen levels which can harm fish.
No restrictions for swimming, fishing, boating or livestock use. Some precautions may apply for irrigation. See product label for details.
