sonar as herbicide label Sonar AS Aquatic Herbicide-QuartSonar AS Aquatic Herbicide is a professional grade systemic aquatic herbicide trusted for long term selective control of invasive aquatic weeds in lakes, ponds, reservoirs, irrigation canals, and other freshwater systems.

Sonar AS Aquatic Herbicide is a professional-grade systemic aquatic herbicide trusted for long-term selective control of invasive aquatic weeds in lakes, ponds, reservoirs, irrigation canals, and other freshwater systems. Powered by fluridone, Sonar AS provides season-long or year-long control of many troublesome aquatic weeds with a single application, making it one of the most effective and economical aquatic vegetation management solutions available. Widely recognized as the industry standard for duckweed control, Sonar AS slowly disrupts carotenoid production in susceptible aquatic plants, leading to gradual bleaching and plant death while minimizing oxygen depletion and water quality disruption often associated with rapid vegetation collapse. Sonar is highly effective on duckweed, hydrilla, coontail, Eurasian watermilfoil, bladderwort, and other labeled submerged and floating aquatic weeds. Unlike many aquatic herbicides, Sonar AS has minimal restrictions on recreational water use following application. Swimming, fishing, and livestock watering may continue according to label directions, though irrigation restrictions may apply for certain sites and crops. Developed by SePRO, a recognized leader in aquatic plant management, Sonar AS has been trusted by professional aquatic applicators and lake managers throughout the United States for decades.Features & Benefits

Good for sitting on it daily. Not that soft as expected
Color: Dark, Color: Dark
I’ve been using this chair for a few days now and overall it’s pretty solid for a home office setup, especially for the price range. Assembly took me about 30–40 minutes alone and all the parts were labeled clearly. Nothing arrived damaged and the instructions were easy to follow, though attaching the backrest was a little awkward with one person.
Once assembled, the chair looks clean and professional. The PU leather feels smooth and the cushioning is definitely thicker than cheaper office chairs I’ve tried. It’s comfortable for working several hours at a time, although I wouldn’t describe it as super plush or “sink-in” soft. The seat has a firmer feel, which may actually be better for posture during long work sessions.
The ergonomic support is decent. The backrest follows the shape of your back fairly well and gives noticeable lumbar support compared to flat office chairs. I spend a lot of time at my desk and this chair helped reduce some lower back discomfort. The reclining and rocking feature is also nice for quick breaks between meetings or while watching videos. It doesn’t recline extremely far, but enough to relax a bit without feeling unstable.
One feature I ended up liking more than expected was the flip-up armrests. They make it easy to slide the chair completely under the desk and also give more room if you like sitting cross-legged occasionally. The chair rolls smoothly and feels stable even when leaning back.
A couple downsides though. The faux leather can get warm after extended sitting, especially in a warmer room. The mesh section helps airflow a little, but not enough to fully prevent heat buildup. Also, while the chair is comfortable, it doesn’t quite feel “premium executive” level in terms of materials. Some of the plastic components and armrests feel more mid-range than luxury.
Overall, I’d say it’s a good value office chair with solid comfort, decent back support, and practical features. Great for everyday work or study use, just keep expectations realistic if you’re looking for a super high-end executive chair feel.

Comfortable chair constructed with good quality materials
Color: Dark, Color: Dark
Having purchased several chairs from Amazon over the years, I would rank the Marsail Executive Office Chair Ergonomic Desk Chair as one of the better quality options I've received. Here is a breakdown of my experience:
Build Quality & Aesthetics
I was immediately impressed by the quality of the base. It is crafted from brushed metal and has a substantial, premium feel that sets it apart from cheaper plastic alternatives. Additionally, the pneumatic height adjuster was easy to install and operates very smoothly.
Comfort & Ergonomics
-- Padding: The padding is not quite as thick as I expected, but it has proven to be very comfortable to sit in so far. Sometimes I am in the chair as much as 10 hours per day, and the foam in the seat holds it's form all day.
-- Support: The chair does not include built-in lumbar support, so I am using a lumbar pillow. However, I actually find this preferable; it allows me to adjust the pillow to my exact needs or remove it entirely depending on how I'm feeling.
-- Head support and tilt: I like to work in an upright position, but I sometimes i like to lean back for a rest. The chair leans back just enough to allow me to rest my head, but not so much that I feel like it will tip over. The head support is subtle too - it doesn't hurt my neck or force me to rest in an awkward position.
Functionality
-- The mobility of this chair is excellent. The wheels are high-quality and roll very smoothly on my hardwood floors, which is often a pain point with other office furniture.
Final Verdict
Despite the thinner padding and lack of integrated lumbar support, the superior materials and smooth mechanics make this a decent value for the money. It’s a sturdy, well-made piece of furniture.

Good quality office chair with movable arms
Color: Dark, Color: Dark
This chair was relatively easy to put together. After unboxing and laying out all of the parts, my husband and I built it in 22 minutes. We noticed how the instructions have you put the tilt mechanism bracket on after putting the back and arms on. Another chair we built was the opposite, which made attaching it to the base actually easier. That way just made more sense.
This way, you put the back and seat together using the arms, then you attach the tilt mechanism to the bottom of the seat, but the seat is at an angle when you do this. Then you lift the whole chair and place it down onto the legs. I'm glad there were two of us to do that part. We also noticed one of the holes for screwing in the arm bracket was not lined in metal like the rest of them were. It still worked, though.
It does rock a bit back and forth. The height adjusting rod also locks the chair in place for when you don't want the chair to lean back. There is a knob underneath that allows you to loosen or tighten how much it moves when you lean back or rock.
The material is faux leather. It looks like real leather and feels pretty good. This makes it easy to clean. The arms can be raised level with the back of the chair to make it easy to slide out of the side of the chair. Overall this chair has a pretty classic look to it and is comfortable to sit in. It even has some lumbar support.
The way the back of the chair and the seat of the chair connect together leaves a little bit of a gap. Nothing major, but you could lose coins or keys through the gaps between the cushions. If you have a cat, this would be a great way for them to poke their paws through and say hello.

Nice office chair!
Color: Dark
This is a nice office chair. All of the features work as stated. I would say the seat is slightly more firm than I prefer, but comfort is subjective. The pleather is soft and I like that the arm rests fold out of the way.
