Professional Systemic Aquatic Herbicide for Whole Pond Treatment

SePro Sonar A.S. is a selective systemic aquatic herbicide designed for comprehensive management of aquatic vegetation in fresh water ponds, lakes, reservoirs, and irrigation systems. With 41.7% Fluridone as the active ingredient, this professional-grade formulation provides season-long control of submersed and emergent aquatic weeds in water bodies with minimal flow.

Label and Instructions

Key Features

  • Systemic Action: Absorbed and translocated throughout the entire plant system for complete control
  • Selective Control: Targets aquatic weeds while preserving desirable vegetation when used properly
  • Long-Lasting Results: Provides season-long control with proper application
  • 41.7% Fluridone: Professional-strength active ingredient for effective weed management
  • Whole Pond Treatment: Designed for comprehensive treatment of entire water bodies
  • Minimal Flow Applications: Best suited for ponds and lakes with little to no water flow

Available Sizes

8 oz (SKU: SO8): Perfect for small ponds and initial treatments. Ideal for treating smaller water bodies or testing the product's effectiveness.

16 oz (SKU: SOP): Mid-size option for medium ponds and lakes. Provides enough product for moderate-sized water bodies or multiple applications on smaller ponds.

32 oz (SKU: SOQ): Professional size for larger ponds and extensive treatment areas. Excellent choice for serious pond managers treating multiple water bodies.

1 Gallon (SKU: SOG): Commercial-grade size for large lakes and professional aquatic management operations. Best value per ounce for extensive treatment programs.

How It Works

Sonar A.S. is a systemic herbicide that inhibits carotene production in target plants, causing them to lose their green color and eventually die. The key to success is maintaining the recommended concentration in contact with target plants for a minimum of 45 days. Apply early in the season, prior to or just after plant growth begins, for best results.

Important Information

This is a restricted-use herbicide and requires applicator certification in most states. Always follow all federal, state, and local regulations. Designed for minimal flow water bodies—consult the label for flow rate limitations. Does not control algae species.

FAQ

Q: How long does Sonar A.S. take to work?
A: You'll typically see initial signs of control within 30-60 days, with complete control taking 60-90 days as the herbicide works throughout the entire plant system.

Q: Why is the 45-day contact period important?
A: Sonar A.S. requires sustained contact with target plants for at least 45 days to be fully absorbed and translocated. This is why early-season application and minimal water flow are critical.

Q: Can I use this in flowing water?
A: Sonar A.S. is designed for water bodies with minimal flow. Significant water flow dilutes the herbicide and prevents the required 45-day contact period.

Q: Which size should I buy?
A: Size selection depends on your water body size and treatment goals. The 8 oz size suits small ponds, while the 1 gallon size is for large lakes or commercial operations.

Q: Will this harm fish?
A: When used according to label directions at proper application rates, Sonar A.S. can be used in waters containing fish. Always follow label restrictions.

Q: Does this control algae?
A: No, Sonar A.S. does not control algae species. It is specifically designed for controlling submersed and emergent aquatic weeds.

Q: Do I need a license to apply this product?
A: Yes, Sonar A.S. is a restricted-use pesticide requiring applicator certification in most states. Check your state and local regulations before purchasing or applying.

Q: When is the best time to apply?
A: Apply early in the season, prior to or just after plant growth begins. This ensures the herbicide has time to work and allows for the critical 45-day contact period.

returned- for now
Style: Updated Formula
I was using the lotion version of this for about a year, then went to the balm for more hydration. However, it seems to be breaking me out. I think because it's spring, im not needing as much occlusion as i did during winter. I'm gonna go back to the lotion formula, then pick this up again next winter. It is a little hard to spread, but I spray the avene mineral water on, let it dry slightly, and press the balm into my skin when its still wet. That helps thin the balm just enough to rub in. Otherwise, it can actually feel kind of rough!

Impressive
Style: Updated Formula
Nice thick cream! I even saw results (skin improvement) within days. I like this way better than their Cicalfate+, as it’s easier to rub in, less greasy, and doesn’t have the water vs cream separation issue. I’m not a huge fan of the pump top for this one, but at least it’s a tube instead of a solid canister (where you can’t see how much is left or get to the last bit).

Excellent for my sensitive skin and rosacea
Another excellent product from this brand. I have type 1 rosacea on my cheeks, even when I avoid triggers (like red wine, warm weather, etc.), and very sensitive skin overall. I've been using the cicalfate serum from this brand for the sensitivity, but it didn't help the redness. After two weeks of using this twice daily, I noticed a significant difference. After a month, I had no redness unless I encountered a trigger. Even then, the intensity of the redness seemed less. I tried going without this product for a month when the first bottle ran out, and sadly, the redness started coming back within a cycle of weeks. I've got this on auto-delivery now, along with the cicalfate serum. I never want to be without it!

Best moisturizer for sensitive skin
I have very sensitive skin and have tried many products over the years. This is by far the best daily moisturizer. I don’t wear makeup other than under eye concealer. This keeps my skin looking and feeling great. Not greasy. One bottle lasts about a month. I have probably bought this 10 times in the past year.
