    No,  I meant they are lying about it being acetic acid.  Someone said these type of weed killers are not acetic acid.

    Can't get anything with lyphosate in here - not that I would anyway - but I see Monsante ar now selling a glyphosate free weedkiller and still calling it Round Up.

    We have a stubborn patch of thistles that has expanded exponentionally since OH decided to fork out the original half dozen plants but didn't get all the roots.  He has now strimmed the tops and I'm about to spray the re-growth and then we'll use a weed burning tool on the new growth and gradualy wear them down. 

    They are, of course, growing in the only fertile seeming patch of earth in the gravel wasteland behind our house where I want to create a Beth Chatto style dry garden.

    @Obelixx Have you ever grown the thistle Galactites Tomentosa a Mediterranean weed ?

    I purchased one plant years ago from Beth Chatto [I think] and it has never left the garden. Some winters like the last one it just survived. Some years there have been hundreds and I have needed to hoe them out. One year they did disappear but turned up in my neighbours garden who  kindly let me have some back.

    They are amazing in the winter when they look like snow flakes against bare soil. I have moved them to fill gaps as they reappear late autumn. In the spring they really start to grow again and flower. If I do have alot I edit before they seed.

    The new roundup, and other products are based on pelargoic acid it does translocation to the roots. The product shown by lyn is not the one I am thinking if . I  agree that this,  if as stated,  is based on acetic acid then it will be much less effective.

    I think the OP is based in the US so will have different products available to them as well as different weeds.

    Some are, some aren't. The RHS has a list that looks reasonably up-to-date - pdf file under the link "Weedkillers for home gardeners" on this page https://www.rhs.org.uk/prevention-protection/chemicals-using-spot-and-broad-scale-weedkillers .
    If that one says it's acetic acid then it probably is. Content labelling is more tightly regulated than the claims that are made for the product, and while manufacturers will use weasel words I doubt they'd outright lie about the active ingredient because that could get them into serious trouble.

    I'm interested to know what your source is @Allotment Boy . Everything I can find says it's a contact weedkiller, not a systemic one.
    Apparently pelargonic acid is also used as a blossom/fruit thinner on fruit trees - that wouldn't work if it did anything more than just burn off what it touched https://applegrowing.niab.com/agronomy-flower-and-fruitlet-thinning/
