I was grocery shopping yesterday and a guy on a mobility scooter was have a little trouble getting jugs of distilled white vinegar off of a bottom shelf. I offered to help, but he declined and managed to get them. He said he mixes the vinegar with cheap weed killer from Walmart, and within fifteen minutes of application the weeds shrivel up. I'm a little skeptical. Anybody ever try this concoction?

sometimes i mix vinegar/ dish soap/ rock salt. best if the weeds are rain wet so the solution gets to the roots. suggestion-- to smash the rock salt, it doesn't dissolve quickly in the mix. use gloves, it will dry out your skin. have a rock bed along the side steps, i just use rock salt, it works.

Pour enough anything on weeds and they will die, water included. Rock salt does not discriminate as to what it kills. Vinegar, in my short experience, is a very short-term weed remedy. YouTube is full of vinegar weed killer videos, all show how fast the weeds wilt, few showing the results a week or two later.
A produce designed for the specific problem is the best solution. And never confuse weed killer and vegetation killer. Never.

One should use 75% vinegar to kill those pesky weeds. Be careful as it'll burn most anything it touches.
Unless you're a chemist and understand such things, adding something acidic to a commercially sold weed killer might not be a good idea. You don't know what you don't know.

Poison ivy around the house... Pour on boiling water! If you are canning this time of year you will have lots of boiling water. Instead of down the drain, put it on weeds. Multi applications required, but what else do you have to loose!
The oily surface of ivy type plants makes them naturally resistant to all manner of poisons, as they just "slide" off; the boiling water may take a few times but it washes through the oily surfaces and effects the stem and roots.
On the farm canning water went to poison ivy for the first weeks and other crawling weed until the harvesting was done (about mid November usually!)

Get a goat.
Sounds simple, but there is more to owning a goat than just eating weeds.

Use horticultural vinegar vinegar, it's at 40% instead of the 5% that you get at the grocery store.
I use 20 Mule Team and vinegar with tablespoon of dishsoap to act as a surfactant.

Weed killer & Pesticide
.
It's good to see conservationists involved in this matter.
Through unwise use of weed-killer, and pesticide, many, desirable Insects, birds, and animals, are already instinct. I'm told that our highly desirable Honey bees, are being affected.
All kinds of human ailments are also attributed to the effects of those products.
This should give us all food for thought.

The bees are dying from mite infestations. And Murder hornets. And probably a few windshields.
I have used vinegar and salt to kill weeds. I works well but gums up the sprayer to the point of having to get a new one rather often. Salt is hard on the sprayer parts.

Go to a farm and home store and by a jug of Amine. You'll need a tank sprayer. though . I've used it for years, and it's the best; kills weeds to the root and doesn't harm the grass.

Exactly.
I know it sounds ridiculous but I actually hold an earned PhD in "weed science" (North Carolina State University - 1986 - kind of a cross between plant biochemistry and agronomy with an emphasis on controlling the most economically important crop pests - weeds). No joke - lots of chemistry and lots of plant physiology and I also know how to grow crops.
Adding vinegar to a commercial herbicide wastes both. Acetic acid causes cell collapse and rapid necrosis of leaf surface tissue which prevents penetration and/or translocation of the herbicide. Always use commercial herbicides in full and complete accordance with label instructions. It's not just a good idea; it's the law - really.
Tens and hundreds of millions of dollars are spent researching all manner of pesticide application efficacy and safety (herbicides are one type of pesticide which is a catch-all phrase for herbicides, insecticides, rodenticides, fungicides, etc.). The use directions on the label are there for a reason - a scientifically valid reason. It's not like marketing shampoo - lather, rinse, repeat.
Most of the "homemade weed killer" concoctions are far more toxic than modern herbicides to almost everything except weeds. Product safety, including applicator and non-target organisms, are paramount in order for a product to be on the market today. Follow label directions and you, and the bees and bunnies, have nothing to worry about. Herbicides are very specific and generally are only active on biological processes found in plants. So unless you're a plant there's not much to worry about (some older insecticides are another matter).

OLDSTER refers to 2,4-D amine. The amine formulation is a low volatility formulation of 2,4-dichlorophenoxyacetic acid - usually abbreviated as 2,4-D. The ester formulation can be quite volatile and may not stay where you put it so amine is the one to look for just as OLDSTER suggests.
This is the oldest commercial synthetic organic herbicide in the history of herbicides and it's still on the market because it's safe and works great (first commercialized in 1946). It's active on broadleaf weeds and will not harm grass if used in accordance with label directions. It is systemic meaning after it is absorbed by the leaves of actively growing plants it is translocated to virtually all plant parts above and below ground to exert its activity. (It is an organic compound but is not approved for use in "organic" agriculture.)
2,4-D mimics a naturally-occurring plant hormone and proves that too much a good thing can be harmful.
Who knew we'd talk about weeds someday on the forum?

And the weeds are still winning, ah yes evolution and nature, they are

41% roundup with a sufactant(makes it stick) from farm supply. Stuff at the big box stores is only 8-10%.

Pfttt....so do many of my clients- Do you know how many varities of bud are out there??
As far as a good weed killer I suggest Roundup mixed with diesel
