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.

Good quality, fairly easy assembly
Color: White
Comfortable chair as advertised. Assembly time about 20 minutes with one screwdriver needed. (Note: don't follow the instructions included. Lay the left arm assembly down on the floor and THEN affix the seat, followed by turning that over on its side and adding the right arm assembly. Trying to affix the two arms in an upright position is too difficult as directed.) The only thing I don't like about it is the fluted upholstery on the seat and back, where a bit more padding would have helped greatly. Otherwise, it's comfortable and functional and reasonably priced. Delivery was on time. ADDITIONAL COMMENTS AFTER 18 MONTHS OF USE: I've used the chair for 6-8 hours a day. The leather on the arms is cracking in multiple places. This is a big disappointment. And speaking of the arms, there's a major problem with the sewing of the leather on the outside edge of both left and right arms: the stitching is on the top at the outer edge, which means that it forms a jagged edge that your arms scrape on when resting on the leather. That jagged edge scraping my skin has caused a great deal of chafing, is most irritating, and could have been avoided entirely if they had just applied the stitching one inch further down on the side rather than along the top flat edge. This is a major design flaw. I will not buy this chair again because of the one flaw and the too-thin, cracking leather on the flat top of the arms, which is too bad, because it's fine in all other ways.

Good, but not great
Color: White
I work from home, so having a really comfortable chair that supports my back and provides me a nice place to sit for 8 hours is really important to me. I ordered this chair in March 2023 and was really happy with it at first. Sleek, easy to put together, and comfortable. I then had an issue with it because after I sat on it while wearing leggings, the entire seat and armrests turned black from the fabric. No other furniture I own turns black from my leggings. I reached out to the seller and they were kind enough to provide me a replacement for the seat and the two armrests at no charge. I went through the whole summer and didn't wear leggings. However, I am now in Oct 2023 and wearing leggings again. The chair seat and armrests are black again, but there is also a lot of wear to the chair in general. I understand I sit in it a lot, but the seat lost its comfort factor. Additionally, I lean on the left armrest a lot and it shows - there is a large indent on it. The fake leather material is just not for me and the chair no longer looks attractive. I wish it lasted longer considering how much I paid for it.

Worth Every Penny
Color: Black
Bought this chair Aug 2023 and as i come up on 3 years with this chair i can say i absolutely love this chair. i bought this chair when i was having very bad back pain and assuming my old chair was to small i decided to purchase it. Zero complaints about this chair at all, no rips, cuts or broken parts. The chair does have some cracking but that's because I'm fat so its a lot for the chair to hold on a daily bases. I give this chair a lot of props for removing my back pain considering my back pain was due to a popped gallbladder that was infected.. If you are reading reviews and looking for a good chair that's worth the money just get this. Its easy to assemble & it has great stability AND most importantly it holds the weight of myself.. I'm built like a butter ball turkey..

1 year review from a teleworker
Color: Grey
I purchased the Homall Office Chair in March of 2022, with high expectations of comfort and functionality. I liked how the chair looked, its price point, and it received positive reviews. Unfortunately, my experience with this chair has been underwhelming, to say the least. Several issues, ranging from poor quality to difficult assembly, have left me deeply dissatisfied with my purchase. Let's start with the assembly process, which was an absolute nightmare. The instructions provided were not terrible, but not great either. It took me significantly longer than anticipated to assemble this chair, and I consider myself fairly handy. If you're not well-versed in putting together furniture, you may find yourself extremely frustrated. Another significant issue I encountered was with the chair's hydraulic cylinder. It has already started failing, causing the chair to slowly sink, regardless of the adjustment settings. This rendered the height adjustment feature useless and made for an uncomfortable seating position. I expected a durable and reliable chair, but sadly, this was not the case. The armrests were also a major disappointment. They started to deform and indent where my elbows and arms sit. The rest of the chair is fine. I can sit it in all day, so that is a positive. I mainly lean a bit forward and don't have time to lounge backward. On top of all these issues, the Homall Office Chair proved to be quite noisy. Whenever I shifted my weight or made any slight movements, the chair emitted creaking and squeaking sounds. Not only was it an annoyance, but it also disrupted my concentration while working and is embarrassing on conference calls. Having such a distracting and low-quality chair in a professional environment is disappointing. If I read this review I would have a couple of questions about the reviewer. I am 6'3" but well below the recommended weight. I review plans and specs as part of my job, so I am good with instructions. My hobby is woodworking which requires skill and a calm demeanor. Yes, I did retighten any connectors that became loose through normal wear and tear. I should have spent more money on a quality chair since I am now looking to purchase a different chair 1 year later. I would advise others to take that into consideration. Spend a little more and keep less junk out of our landfills.

High Quality Rolling Chair
Color: Black/Silver
My son LOVES this desk chair. He has a drafting table to draw and do schoolwork on, and this provides him a comfortable chair to work in. It is sturdy and easy to clean. It does not fold, but it does roll easily. It was VERY EASY to put together. We were also pleased with the price. He will be able to use it for years to come.
