The product I used was Boracil (aka Bromacil).... but this is no longer
on sale.
This was a broad spectrum herbicides for non-selective weed killing, it
entered plants via roots not vis leaves.

Councils used it under tarmac when laying pavements.


Most weed-killers need leaf growth to allow take down to roots .... in
this instance there is no left growth, being used as preventative.
Which would rule out 2,4-D products (and presumably 2,4,5-T)



Anybody aware of a good replacement, or do I need to go back to basic
Sodium Chlorate.

Hard because it was banned a couple of years back. Though some people
may still have a pot kicking about *cough*


Loads of posts on line that Sodium Chlorate has been banned from sale
since 2008 and cannot be used after 10th May 2010 ..

Yet it is on sale on Amazon ?



Nothing on the bottle says Sodium Chlorate. I think they are lying -
it's an alternative. Especially as chlorate was always sold in crystal
form and that item is a solution.
