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.

Very handy
Color: Sienna
I purchased it because I still use paper boarding passes. With luggage claim paper, your passport and ID card, things could get quite messy if you try to put everything in your bag or backpack’s compartment. This one organizes all those nicely. Because of its size it accommodates multiple boarding passes and luggage claim papers easily. (They used to get crumpled in international flights, and It annoyed me.). Yet it is compact enough to carry in your pocket. One negative is its price. It is expensive. But it is a quality product. Nice leather and well made. If you are willing to spend some $, this will spare you from searching your boarding pass and passport frantically at boarding. Highly recommend.

Excellent product, great for travel
Color: Cocoa
I just got back from a business trip and this is by far the most useful passport holder/wallet I've ever used. Lots of room for cards, bills, boarding passes, and a second passport and still folds very flat. Leather is good quality, and is very well put together. Since its too big for my pocket and will mostly live in my briefcase, I expect it to last a very long time. The only drawback is the high price, especially since the leather is probably not full grain (it's not advertised as full grain, so we can assume it's not). But it fits my needs perfectly, even if it is a little overpriced.

Highly recommend.
Color: Cocoa
My favorite purchase for a recent trip across three continents. Fits in pocket (I mean it’s a tight fit, but it will fit). Perfect in cargo pant pocket. Has two separate compartments for paper bills which is nice - you can keep your home currency in one and travel currency in the other. Really sleek looking. Bought four of these and we all loved ours. Highly recommend.

Nice wallet. Just received it and used on trip to Italy
Too early to rate for durability, but it came quickly, looks nice, and appears to be well-made. Was a godsend on my trip to Italy and back. With all the times you have to show your passport (usually dragging your luggage with you), my passport was always at the ready, secure in my wallet in my pocket. I would not travel abroad without it. Not only that, it will serve as my daily wallet as well

Pen holder feature isn't good
Color: Cocoa
Edited review: previously I gave this a two-star review because when I inserted the pen into the pen holder the wallet couldn't close anymore... I tried taking it out putting it back in a few times and it seemed obvious to me that something was wrong and I just could not figure out why the wallet possibly was having an issue closing even though it's designed to hold a pen... To me it seemed obvious that when inserting the pen you should have the clip on the inside where are the bills go.... That single millimeter of space that that clip takes up in the bill fold causes the wallet to not be able to close properly so it springs open. Needless to say that felt extremely cheap for a product of this price and I was very unhappy and considering a return and after writing a bad review I happen to see product pictures with the clip on the inside of the wallet where your cards go and it dawned on me that I had just simply put the pen in in the wrong orientation. That completely solves the issue. So updated back to five stars, and the wallet is great. 2n update after using it for a week on an international trip so I was carrying my passport. Worked great - made me feel safe to always have my passport and room for all my most important documents inside a -just- large enough for a passport wallet. I really don't think they could have saved another millimeter and still made such a quality wallet. Having a micro pen in there is icing on the cake - makes you feel like James bond. I also felt safer having a hidden bill compartment so your not showing a fat stack of foreign currency (I mean depends on your use case but I was in some rather poor areas and this added some peace of mind and 'security' in my opinion). You can just keep some small bills up front and your real stack on the hidden flap. I won't dock a star for it - but keeping this on a back pocket so you're sitting on it because it's bigger and the way it holds cards after just one week there's already card imprints on the leather (just imagine your older leather wallets where the cards start wearing through the leather) Also I tested the RFD blocking and it indeed works. I'm unable to scan any cards through the wallet and that was an important feature to me. Even when the wallet is open and I ran scanners directly over cards (in the sleeves) it still didn't pick anything up.
