Strong weed killer while we still have EU laws on the books ? {Sucks in air, shakes head, and tuts} Naw, no such thing any more, not now we have to protect the weeds... er... I mean environment. Have you tried vinegar ?
We had a problem with equisetum in a hay field years ago and you really need something heavy duty to get rid permanently. No point spending less and having to repeat the treatment.
I've had this weed on my rockery for a number of years. I (almost) manage to control it by hand tugging. A thankless task indeed!
It's also appeared in the cracks between the paving stones on my patio. A gardener friend suggested a generous squirt of Bramwell's distilled malted barley vinegar (29p / 568ml from Aldi).
I splashed out last week on a small area and it seems to have at least frightened the stuff, if not completely killed it. For 29p it's got to be worth a try! Probably OK for patios rather than borders though.
