Benefits of Paraquat Dichloride 24% Sl
- Fastest knockdown weedicide: Visible wilting starts in 2 – 3 hours, full kill in 24 – 48 hours fastest action of any weedicide in India
- Rain-fast in 15 – 30 minutes: Best choice for monsoon spraying when sudden rain is a risk
- Wide crop approval: CIB-approved for tea, rubber, cotton, aquatic weeds, coffee, potato, apple, grapes
- Soil-safe: Binds tightly to soil on contact does not leach down, safe to plant new crop after 1 to 2 days
- Inter-crop friendly: Safe directed spray in orchards and plantations does not enter through tree bark
- Cost-effective per acre: Lower dose than glyphosate, faster results, lower per-acre cost
- Works in cool weather: Effective even in winter when glyphosate becomes slow
How Does SUMAX Work?
Paraquat is a contact herbicide it works very differently from glyphosate:
- Sprays on weed leaves: Paraquat enters the leaf surface in minutes
- Disrupts photosynthesis (PSI): Blocks the photosystem I in the plant cell
- Creates damaging free radicals: These oxygen radicals burst the leaf cells from inside
- Plant dries and dies: Wilting starts in hours, full death in 24 – 48 hours
Important: Paraquat is a contact killer only it does NOT travel to roots. Perennial weeds (Doob, Motha, Kans grass) will regrow from roots. For root-level kill on perennials, use Glyphosate 41% SL instead.
Paraquat (SUMAX) vs Glyphosate — When to Use Which? SUMAX (Paraquat) = fast knockdown in 24 – 48 hours, rain-fast in 15 minutes, best for tea, rubber, cotton pre-sowing, aquatic weeds, and inter-crop spray where you need quick visible results. Glyphosate = slow but kills roots also, best for tough perennial weeds (Motha, Doob, Kans) and pre-sowing fields where you need full root kill. Many farmers tank-mix a low dose of glyphosate + paraquat for both fast knockdown and root kill.

Great chair
Color: Black
I am very happy with my purchase. Easy to assemble but be aware your drill bits included with your set won't fit their screws. However, you can get a fair bit done with the drill and then use tool included to adjust. Super comfortable and exactly the right height for my desk. Highly recommend for quality exceeding price point.

Review from an "actual" tall person who doesn't weigh 400 pounds.
Color: Black
I recommend this chair.
Firstly, I looked at least dozens of chairs and nearly every review in trying to select a chair. I didn't want to spend $200.
It's confusing because everyone's idea of perfect is of course subjective. One thing, What is tall? I'm 6'6" I think that's pretty tall. Others feel that 6'0" is tall. LOL In the listing, it shows this chair is good for a 6'5" person which I think is pretty accurate. I weigh about 210 pounds and the padding is just fine. One thing I would push manufacturers to do would be to give accurate measurements. Seat height low and high. Back support height. Head rest added to back height etc.! Maybe actual human measurements that the chair is geared toward. Nice to know that 400 lbs is cool but that doesn't tell me much.
My primary goal was to find a chair I could sleep in because I recently had a
back injury and sleeping on my bed, while fine, resulted in intense pain trying
to get up in the morning. We'll see what happens but the headrest reaches my head
which was goal one.
The lumbar fits so I don't need to use cushions and pads etc. I found the upper
position of the support to be right for me and it's super comfortable. Plus number
two.
The raised height of the chair fits my long legs (inseam 36") Plus three.
I wanted adjustable arm rests but this one doesn't have that. No biggie, for me the height of the arm rests is pretty much just right. It might be a little high for some.
The back leaning adjustment doesn't lock except for upright. Locking upright is good, and leaning back - for me - doesn't really need to lock.
Being an actual tall person made me really skeptical. I'm relieved that I won't have to take it apart to return it. The assembly was straight forward and pretty easy though I'd suggest not really tightening the arms snugly before getting the back squared away - the alignment is easier if you do that.
I got the chair for $109 with 21% off. It's slightly wobbly yet feels pretty well made. It rolls well enough.
I'm quite satisfied with the purchase and I'll come back if there are updates.
Edit one. I've had it a week now and found I couldn't sleep in it. I think it would be better if the back could recline separately from the seat. There might also be figuring out a way to support my legs due to the back and seat reclining together rather than separately. Two. I kind of wish more now that the arms were adjustable for height and tilt if that makes sense. I have a bar stool next to me on the right in front of my desk that is the right height to relax my right arm while reaching my mouse on the desk so that's my work around there. Three. The casters are kind of basic and don't roll as easily on the floor matt as my former second hand chair - they would probably be fine on a hard surface. I'll probably switch them out. Four: The lumbar support, while mostly in the right place is unpadded and creates kind of a hard spot there. I've re-introduced my lumbar support pillows for comfort there.
All in all, I'm still happy with the $100 purchase. In my experience, being pretty tall always comes with compromise and these notes are not deal breakers for me.
Yea, It can always be more perfect but unless you're in a showroom test driving and willing to spend $300? Right.
UPDATE: I'm really not satisfied with this chair and in fact, I wish I hadn't bought it. Firstly, the pneumatic post that the chair part connects with is wobbly depending on which way it is facing according to which way the legs are aligned. It's like a poor fit and I'm pretty mechanically inclined.
Second and also important. The lock to keep it upright and inclined only worked for a few weeks. For a while, you had to mess with it to engage the upright position. It no longer works.
Worse than that, the lumbar support pad disconnected with the chair and is now floating and after only a month or so, the remaining supports for the Lumbar rest have dug into the fabric on the back of the chair creating holes in the back's fabric. I've tried but there is no way to reconnect that bit without removing the back's fabric as far as I can see.
I'm taking this down to one star for sure. Poor design? Poor manufacturing? Yea. I wouldn't suggest this chair to anyone. If the company comes up with a solution, I'll continue my review.
As for now. Not a recommendation.
Update: Not impressed and kind of crappy. Mentioned is that the so called lumbar thingy disconnected and is unusable. I've got my own pad which seems to help. Also, it's wiggly where the chair connects to the base. Months later, I might toss it and go back to the chair I bought locally and second hand.
Don't buy this chair!

Great Instructions, Straightforward Assembly
Color: Black
I just received this chair today, so my product review is mostly on the packaging, instructions, and assembly.
The product was well-packaged, and it was obvious when I unboxed it that a lot of care and thought went into packing it in the most efficient way that would also protect the parts. I was positively impressed with the packaging.
I was also incredibly impressed with the instructions and assembly process. I am used to cheaper products where the parts only half fit or important components are missing, or where the instructions were confusing and unclear. This chair's instruction manual was very clear and concise. The diagrams were easy to understand and neat. The screws came labeled and separated and also included the scew types and sizes/lengths, which is handy in case you need to pick up extras at a store somewhere. But they also included one extra of each type of screw, washer, and cover, which I appreciated during assembly. (I didn't find myself worrying what would happen if I dropped a screw, which is something I would normally be distsracted by while working.)
The only things I would take points off for were these:
1. The instructions said the chair came with gloves for assembly, but no gloves were included. That was fine with me, but why mention them if you won't include them? The instructions even later say not to use the chair if not all components were present...but all the important ones were, so I assembled it without gloves (as I probably would have done anyway, since it was for me and not another person).
2. It matters which side of the seat is the front, but the sticker was confusing. The instructions show a sticker placed on the side that is the front, and that is where my sticker was placed. However, the sticker says "FRONT" and has an arrow pointing somewhere. In the instructions this arrow pointed to the front. On my seat, however, the arrow pointed to the back. So am I supposed to believe the sticker placement (it was diagonal, so it looked haphazardly slapped on) or the arrow? On that particular step the piece you are screwing into the seat can fit both ways, but thankfully there is a later step where it becomes obvious which side is the front vs. the back. (The arm rests can only be attached to the back.) So I wish that had been clearer up front, but otherwise it was okay.
Recommendations for assembly:
- To attach the wheels, apply firm, direct, straight-down pressure. I tried screwing them on at first but you just push. Make sure they go in the whole way like the picture shows.
- When they say to tighten the screws to only 60%, it's a helpful tip, because you can't fit the armrests on both the seat and chairback at the same time with the screws completely tightened. Just tighten them enough to fit the pieces on, then later you can tighten up the screws.
So far I find the chair to be very comfortable and I'm exceedingly happy with it. The lumbar support seems like it could potentially be a little chafy or scratchy, but I'll give the chair a chance before deciding if it's problematic or not. Like I said, I only got the chair today, so I can't speak much to its long-term comfort, durability, or longevity. But I was so impressed with how easy and straightforward they made the assembly that I had to write a review to show my appreciation.

It's okay
Color: Black
Appeared to be a super comfortable chair. Purchased for my mother to work from home and the material is apparently slightly itchy and the arm rest isn't quite comfortable. It was pretty simple to put together but it did take some time.

An Actual Nice Chair for a Decent Price. +2 for the Tool.
Color: Black Grey
Welp, My old chair finally broke, so It was time for a new one. I ended up coming across this chair here, and I couldn't really find anyone talking about it online. I decided to give it a shot since it was on a good sale for Christmas, going down to 99$. I'm going to be honest, I am pleasantly surprised. The cushioning for it is a little firm, but that is perfect for me. Its pretty average when it comes to office chairs, but having the added lower back support is a great touch. I have no complaints about it.
The one thing that I am actually really happy about isn't on the chair. Don't get me wrong, over the week I have been using it, It has been nothing but great. That thing is the actual tool it came with. Its a basic Allen key, but the top of it is a molded handle instead of a "L" piece of metal. It made the already easy process of putting together this chair even better. Even after this chair has ran its course like all other chairs, I'm going to still use this tool.
So yeah, I think 5 - stars pretty accurately describes how I feel about my chair.
