Sonar Q Aquatic Herbicide, SePRO's pellet formulation, selectively controls undesirable aquatic vegetation for a year or longer. Sonar Q is your best choice for season long control of all pondweeds in ponds with sandy or firm bottoms.

Cannot ship to the following states:

• Alaska
• California
• Connecticut
• Maine
• New York
• New Jersey
• Washington

• 5 lb of aquatic herbicide pellets in a shaker container with handle

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.

Timing
Sonar Q can be applied starting in early spring, at the first sign of weed growth.

Pond Level
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.

Dose
The dose for the first Sonar Q treatment is normally 20 lbs. per surface-acre depending upon depth (see product label).

Application
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.

Control Time
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.
