This is a good deal if you want to pay extra for the Roundup branding. Roundup Super Concentrate is just 50% glyphosate concentrate.

Compare that to generic glyphosate 41% concentrate which is about $21 per gallon: https://www.amazon.com/Compare-N-...glyphosate

I get the generic glyphosate in the 2.5 gallon jugs or larger for use around the farm and it works the same as the small bottles of Roundup - I wouldn't waste money on brand name (it's just like brand name vs generic prescriptions)

Do we need to mix this with water? Sorry. Completely new to all this.

Yes, you mix it with water. The only time you'd use undilluted concentrated glyphosate is if you had just freshly cut down a tree and wanted to try to kill the roots - brushing glyphosate on the stump can help it dry out faster.

Normally if you just want to spray weeds you would mix a small quantity of glyphosate (follow the instructions on the jug) with water in a sprayer. This little 1 gallon sprayer is more than enough to do spot spraying for most small homeowner jobs: https://www.amazon.com/gp/product...UTF8&psc=1

Keep in mind that ANYTHING you spray with glyphosate (Roundup) will die. If you spray a dandelion weed in the middle of your yard, and some of the spray gets on your grass around it - now you have a dead grass spot. So be very careful with it; it's probably best to use it in flower beds or somewhere that you have mulch and don't have to worry about overspray. It's also good to kill grass in places you don't want it, like under your fence.

The nice thing about glyphosate is that it just kills once and then it's done - it doesn't stay in the soil for more than a day or so. You could spray the weeds in your flower bed today, then tomorrow go and plant new flowers and you wouldn't need to worry about the residual glyphosate killing the flowers.

But, that also means that it's not going to "keep killing" weeds like some sprays - you would need to reapply as weeds pop up.

If you have weeds/grass in the cracks in your driveway, or growing up next to your house / foundation, or otherwise just want to indiscriminately kill all grass / weeds in an area - glyphosate is what you want.

Please stop using this stuff or anything with glysophate. Does it work? Sure. But so would dropping a nuclear bomb in your yard (which, this stuff is not far off...just much slower and less dramatic). You can google for yourself the reasons why.

Plenty of great/cheap alternatives out there. White vinegar is a great weed/grass killer.

Glyphosate works fine and has been on the market for 45 years. It's well researched and is the most used herbicide out there. Here's what the World Health Organization says about Glyphosate:

The WHO and FAO Joint committee on pesticide residues issued a report in 2016 stating the use of glyphosate formulations does not necessarily constitute a health risk, and giving admissible daily intake limits for chronic toxicity. The European Chemicals Agency (ECHA) classified glyphosate as causing serious eye damage and toxic to aquatic life, but did not find evidence implicating it to be a carcinogen, a mutagen, toxic to reproduction, nor toxic to specific organs.

Basically don't splash the stuff in your face and you'll be fine. You should always wear gloves and protective gear when handling any type of possibly dangerous chemical including pesticides and herbicides.

White Vinegar is highly acidic, and just like glyphosate it's a man made creation (vinegar isn't something that just is found naturally in the vinegar plant, you know). Pouring a strong acid into your yard is probably no better for the ground than a strongly diluted herbicide that your neighbors are using anyway.

Oh, and saying that glyphosate is like a nuclear bomb because it will kill your grass - uh, yeah, that's exactly the point of the product. If they sold nuclear bomb-based herbicide on Amazon I'd use it instead, but in the interim I'll stick with glyphosate for spot spraying the weeds and 2,4-D for broadcast spraying the yard and pasture.

What am I missing? I don't see a coupon.

I see - had to add "from other sellers" the one sold by Amazon for the coupon to show in my cart.

Do take note of it being toxic to aquatic life if your runoff goes into a nearby body of water (be it lake, stream, or ocean). Pretty much all of the runoff here in southern California goes straight, untreated into the ocean, so think about that next time you go fishing off a pier.

It is a little more complicated than don't splash it on your face. Env impact and uptake has ongoing concerns as the research doesn't show it in quite the nice light monsanto likes to paint it. (Look at acceptable limits between EU and US) One example from a source that should be fairly good at doing it's dilligence. https://www.chemistryworld.com/ne...10.article

Vinegar has issue in terms of application danger (20% stuff) and env impact if you spray indiscriminately and get it on non plants (like amphibians) since it is an acid, but it shouldn't persist in the env. And it may not work well on perennial weeds.

I don't care about the environment so recommend me something that will permanently kill and prevent weeds and any other vegetation growing through my rock landscapes.

Have put down fabric, plastic, roundup, tried the vinegar salt soap combo, sprayed gasoline, NOTHING! weeds keep growing. I don't care about the soil underneath, I want nothing ever growing in these areas again. Recommendations?
When you say you don't care about the environment that is like saying you don't care about yourself you are part of it you ignoramus
