    I'm about to use Neudorff for the first time - due to arrive this Friday. I'm a long time, but careful user of glysophate. Whilst that is very effective long term, it can be two or three weeks before plants show signs of dying. Neudorff, on the other hand, is claimed to show signs very quickly, but it is not clear how effective it is long term.

    Has anyone combined the two - and with what result, please.

    Neudorff - they make the QVC Richard Jackson weedkiller - bit of useless info :blue thumb:.

    But back to the question - I wonder if the weedkiller contains Geranium extract - this kills the whole weed in 24 hours?

    What does the contents label say?

    Mervyn, my experience is that glyphosate works reasonably quickly.....certainly in a week.
    Sounds a bit like overkill.....forgive the pun !

    I have seen, now and then, Richard Jacksons products but never convinced by them.

    There are glyphosate products out there with claims to kill instantly......since glyphosate needs time to translocate the chemical to the roots I wonder if a quick killer would negate the efficacy of glyphosate!!:noidea:

    Like Clanless, I would read the label :)

      Thanks to Clanless and Verdun for the comments. I believe the main 'ingredient' of Neudorff is pelargonic acid. Feedback on Amazon suggests very rapid wilt.

      I have an acre of garden. Some if it I claim is semi-wild! Certainly, without glysophate I wouldn't survive. Typically, I will use getting on for 3 litres of concentrate in a year. I find that it is two weeks before I see any real signs of wilt, regardless of the strength I use it at.

      It seems to me that if the Neudorff acts as quickly and effectively as feedback on Amazon suggests, a belt and braces approach of combining it with glysophate might be worth a try. I think I will do an area just with Neudorff and another one with the combination - and see what happens.

        Plants treated with glyphosate might show signs of distress after a week, but as the whole point is that it's also meant to destroy the roots of perennial weeds, it can take anything up to 6 weeks to accomplish that completely.
        Friends here have tried the new stuff based on pelargonic acid on paths and driveways and found it totally ineffective. I hope it works better for you Mervyn!
        What I find disgraceful is that the packaging in most cases is identical to the previous, effective products, so unless you read the label carefully, you don't even realise that it's changed. Same goes for insecticides, fungicides and fertilisers. Sharp practice.

          Thanks for that noisette. I've paid my money and I'll see what it does and report back. The extensive feedback on Amazon is very good. I wouldn't have thought about using it on hard surfaces.

          The trouble is that the useful weed killers that we had until a year or two ago have gone. I have diluted concentrated acetic acid. It is quite effective, but the dilution process can be a but risky.

            I was slightly amused when I noticed that I am designated an apprentice gardener. In terms of membership of this forum that might well be appropriate. However, I have been gardening an acre since 1974, including turning the land from being a field!

            I've been using something called "Weedol Rootkill Plus".
            Apparently it contains Glyphosate and something called Pyraflufen-ethyl, it does have a reaction much faster than just straight Glyphosate.
            Must admit I was a bit concerned that it was killing the top growth off before the Glyphosate had chance to be absorbed, but it does seem to work.

              I was 9 years old in 1974 :biggrin: - no interest in gardening until we moved into our current home. Mind you I think that retirement has helped as I've lots of spare time now :dbgrtmb:.

              Welcome to the forum @Mervyn Wilmington.

              When you say 'combine' do you mean mix together?

              As others say your best bet would be to spray with glyphosate first as that is systemic and needs a few weeks to work its way through the plant and into the roots. I can't see much point in spending money on another product unless it's for aesthetics ?

              I was 15 in 1974 and I'm not allowed to retire for another 7-8 years and then only if I behave myself.

                I would be careful about mixing them together unless the labels say they can be mixed.
                You can still get sulphamic acid (compost accelerator) from EBay and Amazon this is a very effective total weedkiller even if not approved by DEFRA. As far as I know it was not approved due to the cost of the testing required rather than being dangerous to use.

                  Some interesting points!

                  Using both would be for aesthetics: dispose of dead looking plants more quickly.

                  I have a built-in resentment using Weedol - the prices are silly high. I buy glyphosate in the commercial 5 litre bottles.

                  I hadn't heard of sulphamic acid: I will investigate.

                  As an addendum, what, other than a hoe, do members use for annual weeds, please? The useful weed killers for this purpose seem no longer to be available.

                  Maybe a flame thrower would do the trick for you Mervyn - they come in all sizes from a little £13 job from Aldi to farmer sized units:
