strong weedkiller?

Hello all

Around my property I have a large area of weeds that needs clearing. I have previously used Sodium Chlorate but have just found out that it has been banned by the European Union. Some of the weed is Japanese knotweed.

So the question is, what is the best thing to buy to eradicate it and where can I get it at a good price?

Thanks for any help.

Anything with glyphosate in

Wilkinsons is cheap otherwise any bodies own brand is cheaper than the names ones.

 

Thanks a lot - I'll give that a go.
