Japanese knotweed is extremely resistant to chemicals. ,here in cormwall we have been trying to eradicate it for years. I noticed a patch where knotweed was supposed to have been eradicated for it now to be appearing with even greater vigour. This is on council land. As things stand jap knotweed is winning
I well recall being shown jap knotweed being burned to a crisp yet was starting to shoot again a few months later.
Leave it......I.e. removing shoots as,they appear......and it will take over.
If I had any knotweed in my garden I would move.
