FAQ

What is Sonar used for?

Sonar fluridone is a broad spectrum aquatic herbicide used to treat a wide variety of submerged weeds and duckweed in ponds.

What is the active ingredient in Sonar?

The active ingredient is fluridone. Each Sonar product has a different percentage of fluridone.

How to apply Sonar herbicide?

Simply pour the Sonar into multiple places around the pond and triple rinse the bottle. Natural water mixing does the rest of the work for you. If you are treating a large body of water, you can apply Sonar more evenly across the lake using a subsurface injection system.

Is granular or liquid better?

Both forms of fluridone will disperse throughout the entire body of water. Depending on which exact product you’re looking at, they have different percentages of fluridone in them.

How does Sonar compare to Spritflo fluridone herbicide?

Spritflo fluridone and Sonar A.S. have the exact same active ingredient in the exact same quantity. Save when you buy our brand!

When will I see results after applying Sonar?

You’ll see results 30-45 days after application.

  1. Carl (verified owner) –

    My wife and I had agonized over our “ugly” pond for several years before we finally decided to spend the cash and hope for the best. We went with the sonar because we had a severe miliweed / milifoil ? problem. Our big problem is that our neighbors pond overflows into our pond and they have the same problems. We treated our pond and over the course of several weeks we noticed a big difference. The kicker is I’m writing this review about 4 years later and our pond is still in great shape which I find incredible. Our miliweed is still almost non existent even with the overflow, and the host of critters that go from our pond to several in the neighborhood. As a side note, over the summer months the neighbors pond is covered on top with the miliweed to this day. We are starting to get some of our spatterdock infestation back so it may be time to re up on something that will beat it back a bit. Overall, we were and still are thrilled with the products we ordered from lakerestoration.com. Thank you!
