Sonar Q Aquatic Herbicide
Sonar Q Aquatic Herbicide
Sonar Q by SePro Technologies is an aquatic herbicide that comes in the form of a Sonar pellet which makes for a quick, easy-to-apply formula that selectively controls undesirable aquatic vegetation for a year or longer.
It has the efficient concentration level of a liquid herbicide but the granular formulation provides for more accurate placement. The pellets will land where they are thrown, eliminating overspray onto sensitive shoreline vegetation like lawns. If you're looking to control aquatic weeds and want an easy hassle-free option, Sonar Q fits the bill.
Tools Needed
Sonar Q is ready to use right out of the bag. The only tool you will need is a plastic scoop or spreader to distribute the pellets or you could disperse the pellets directly from the container.
How to Use
- Step 1: Read the product label for complete instructions before applying products and for specific instructions for application rates depending on the size of your pond or water body.
- Step 2: Spread pellets directly from the container into the water. Apply Sonar Q at a rate of 20 pounds per acre at an average depth of 4' - 6' or 4 lbs. per acre-foot.
- Step 3:The labeled rate for Sonar Q should be split and applied in two applications about 10 - 14 days apart. For small ponds, the application can be made from the bank. Spread pellets directly from the container into the water.
