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.

Super Satisfied Customer Here!
Color: Gold, Color: Gold
I purchased the gold/black mug warmer. I always spend a good about of money for great coffee products and I take my time to perfect my coffee for my mornings at work. However, I get pulled into urgent meetings and just something urgent and I always leave more than half of my coffee behind. When I come back it’s cold and that’s very disappointing considering the money and time I spent to make it bc I then have to toss it. I don’t believe in microwaves and I refuse to use one. When I found this, I was super excited! It looks perfect at my desk and it works perfect! I would have liked it to be more on the brass gold like my pen holder, but it’s just as pretty! As you can see, my mug had a layer on the bottom and that made me think it may not work well, but it did the job. My coffee was super warm and it got even hotter as I left it there tearing it. I turned it one before making my coffee, so I’m not sure exactly how long it took to warm up but for me, by the time I got back, it was the peg temperature. I highly recommend this to anyone who has the same struggles. No more cold coffees! Thank you!!!

Works great, easy, convenient, safe and priced right
Color: Black
This warmer is just amazing. I tend to nurse a mug of tea from morning to night. This warmer has three different temperatures. I always start out at the high 167 but as I drink my tea and there’s less than a cup, I drop it to 149, and when it gets lower, I can drop it to 131. Keeps it at the right temperature all day long. One of the other things I love about it is that if I leave and forget that I still had some tea sitting there, it turns itself off after four hours. It is so convenient to use because you don’t have to turn it on or off. You just set your cup down on it and it automatically returns to the last temperature you used. I bought my first one in 2021 and now have five of them. I keep one in my bedroom, one in my family room for when I’m watching TV, one at my office desk, one at my partner‘s desk in his man cave, and one in the camper. I’ve tried many different brands and styles in the past and I can assure you this is the best. Enjoy.

THE ABSOLUTE BEST MUG WARMER! WORKS PERFECTLY!
Color: Black
This is the best mug warmer I've ever had! It's sleek, keeps drink hot or even warm if that's what you prefer. I bought two, my niece liked mine so much she got one, and I'm getting one for my guest who comes to my house.

YEOSEN 3 Temperature Mug Warmer
Color: Black
Wow! There really are warmer mug warmers than lukewarm! This is one of them. Who wants lukewarm coffee? The YEOSEN 3 Temperature Mug Warmer on the MEDIUM temperature setting keeps my coffee HOT enough. Not lukewarm, or barely warm (even at the bottom of the cup). In fact, I use the lower temp. settings, while the level of liquid goes down. The lowest temperature is HOT enough ...not lukewarm. It's not burning, but HOT. I bought it because the reviews said it kept the coffee much warmer than lukewarm. And it does. The point is, when I walk away from my desk for 15 minutes, the temperature of my coffee is still satisfyingly hot. After all, what is lukewarm? It's a few degrees above normal body temperature! 137 is hotter than that! The unit automatically shuts off (the Off-On button is on the bottom of the unit positioned under the hot plate and the weight of the cup pushes the button to turn it on), when you pick up the cup it shuts off. I don't like the auto shut off button on the bottom of the unit. It shuts off and on every time you take a drink. Lift the cup up and it shuts off, set it back down and it turns back on. Wish you could shut that feature off. A piece of tape? but unplugging it from the wall is inconvenient. Maybe, because it's so much warmer than lukewarm, it needs some kind of safety feature. But, all in all, I would definitely buy another one.
