Far, far cheaper than anything you can buy from garden centres - same stuff, but much more concentrated and needs to be diluted.

Even stronger than the Gallup 360, but a bit more expensive.

Also sold as Roundup and Resolva - but this is almost 70 times stronger than the standard formulations you find in garden centres.

Be aware of the warning at the bottom, though, which applies to anyone using this professionally. Needs sensible handling.

For use only as a herbicide for the control of annual and perennial grass and broad-leaved weeds in stubbles, set aside, orchards, forestry, and non-crop areas, and for pre-harvest use in cereals, oilseed rape and linseed.

Also sold as Roundup and Resolva - but this is literally 68 times stronger than the standard formulations you find in garden centres.

This is cheaper, but not as strong: hotukdeals.com/dea…335

Stock up before this is banned!

Good stuff but bear in mind it can kill nearby plants no matter how careful you are about not getting it on them. For those you'd be better with the manual method of ripping weeds out by hand.
its potent stuff. be carefull with it.

I agree. Mixed at 1 to 4 with water so I doubt it's anywhere near the strength of this deal or the 360g per litre stuff.

Quite alarming that this is sold on eBay, as a professional I need to show my licences to purchase this and the are strick rules about use and storage. Shocking.

Great stuff, as has been mentioned though, professionals have to show competence by means of qualifications before using pesticides and weedkillers in this sort of concentration, this should not be sold in such large quantities to the general public in my opinion to try and minimalise possible contamination to watercourses via spillage or incorrect dosage and storage, also all gloyphosphates derteriorate in strength after a couple of years or less and become far less effective. Great price for the contractors and landowners who need this amount though. Trying to locate a data sheet that gives an effective kill rate on bracken rhizome.

Just bought the last one. Thanks op we live next to an old quarry and get really thick, tall nettles, thistles and brambles, would like to kill all this off and put a load of wild flower and grass seeds down so that it’s nicer to look at.

For the '360' products, I believe that the correct dilution is about 25ml / 1l
So, for a '490' product, the dilution would be even more.
At your dilution, you are using something that is much too concentrated and wasting money at the same time.
The product *does* come with dilution instructions on the back (often under a peel-away label).

It'll kill the leaves but not the roots. As far as I know the only way to get rid of Japanese Knotweed is to take buildings apart and remove the roots by hand.
Edited by: "Zuulan" 11th May
Best way to tackle knotweed is inject the stems every couple weeks for 4 months or more.
though it is possible it will try to come back even after 20yrs so keep an eye on it. be very careful with any cuttings! dispose of properly you don’t want it growing all over the place.
I’m not any expert or anything but this is is what our gardener done.

Not exactly my 'amazing discovery' - just hard, well acknowledged fact.

You'll need to read a little further beyond attention grabbing news stories if you want to learn the truth, and the last link is the detail behind the BBC story, which includes the comment:

"Ignore the hysteria - your house will not fall down. Knotweed can be controlled using glyphosate at the right time of year, though this can usually take three to five years. However, we don't recommend you do this yourself – we have seen mortgages declined because of botched treatment undertaken by homeowners."

So you should amend your post to say 'control' rather than 'kill' in your "attention grabbing" title!
Glyphosate is strong stuff.

Regardless on how it is sold, it is believed to be cancer-inducing, kills green plants, it is harmful to fish and, contrary to claims to the contrary, it remains and poisons the soil.

I use this stuff once or twice a year in my yard under duress. The concentration I use is less one capful to 25 litres of water in a backpack sprayer. And it kills every green plant it comes in contact with.

I suspect that 5 litres will be sufficient to turn brown at least 3 acres of grass, or a couple of football pitches or more.

If a normal punter living in a normal semidetached decides to buy this, in this professional concentration, they will be saddled with it for years and years and years to come, and when they decide they no longer want it, they just will not be able to dump it down the drain and sleep peacefully ever since.

Don't you think you're being just a little silly and pedantic, just because you don't understand the subject and made a claim that couldn't be substantiated?

From the RHS (you might need to look that one up):

It usually takes at least three to four seasons to eradicate Japanese knotweed using weedkiller. Professional contractors, however, will have access to more powerful weedkiller that may reduce this period by half.

This is the more powerful weedkiller referred to by the RHS.


You don't need to buy the stuff if you don't want to, but as for 'attention grabbing' I'm pretty sure that anyone with a Japanese Knotweed problem would be quite interested to find a way of dealing with it.
This is great stuff. Used it to kill off a load of mares tail in our front garden. Used a mixture of 300ml to 5 litres of water which is approx. 3 times recommended strength and after 2 applications no more mares tail!

I did not want anything living in my front garden which is laid to gravel mainly so did not need to be careful however if you have plants you want to keep you may end up killing them off even if you are careful. Use with caution!!

You need to be really careful with this though. Wear gloves and cover up your skin and wear a mask ideally dont get it on your skin.

No, I’m not being silly or pedantic (resorting to insults, nice!)

The world's largest field trial on the control of Japanese knotweed, conducted in Wales, has found that eradicating the plant is not possible.


This is the latest research. You can post as many old links as you like, but this is the most up to date study. It says eradicating the plant is not possible.

As you have correctly pointed out, you can control it, but I only commented on your claim that you can kill it.
