i've seen lots of it in the middle of nowhere in connemara.

i do recall seeing news of a pilot project to introduce a japanese insect to the UK which i think was a knotweed sap-sucker. i haven't heard anything about whether this was a success or not.

I've heard of similar rumours re an adversary for those nasty little slime balls from NZ too, but don't know if it's true either.

sorry no, sure try an experiment start with normal cup of coffee and if that does not work go to very strong, It was an experiment from a school and not industry so therefore it should not be too difficult to try.

What does this stuff look like. ?
I have a nasty creepy thing that is wrapping itself around my roses and hedge bushes.
Could somebody post a picture of this invasive weed?

Put up a picture of your 'nasty creepy thing' and someone might identify that for you instead. Not to put too fine a point on it but if you have JK you are screwed.

No need for that, tagwex. Smile
But I may give you "Freddies curse".

Did you ever hear of "Freddies curse"?

Visiting Wisley some years ago, I saw an interesting method for dealing with bindweed in a mixed border.
The gardeners were training it up a pyramid of sticks, like runner beans. When it got big enough, they were going to hit it with glyphosate, without damage to surrounding plants.
I suppose you could even wait to enjoy its attractive flowers before knocking it off.
Thankfully it's one weed I don't have, though it for some years it has been approaching my garden via a tall whitethorn hedge on the roadside nearby. I wait till it's well grown and pull lumps of it out, hoping to stop it from getting near enough to send seeds my way.

Thanks Wiseley.
I am pulling it up every day but it's hard to keep ahead of it.
I will hit it with that 'GLYPHOSATE' soon and see what happens.

I planted a AZELIA (spelling) shrubs this spring and they are being attacked by that feckin stuff now. The fight goes on eh?
