Just don't buy Roundup or pre-diluted "read to use" glyphosate as you
will be paying something like ten times the price (per unit) as the

Where do you get the generic concentrate?
I haven't seen it on sale in any garden centre.

In supermarkets in (at least rural areas) sunny .fr

The active principle is formulated with excipients to aid wetting and to
open the stomata so the product is properly absorbed.

For deep-rooted plants it's best to use a high dilution, so the stuff has
time to get to the roots before the top growth is killed off. It may take
two goes.
