Zero doesn't work, it's far too weak. I've foudn it only knocks it back
for a while and it then starts off again. I've been trying to eradicate
a huge wad of from a large bed for at least 10 years and the only thing
that seems to work is tree and blackberry poison which has 50g/L
TRICLOPYR present as Butoxyethanol Ester.
I was writing about cut and dab on cut part within 5 seconds, as it then
sucks it into the plant..
Did you try spray as well as me?
Haven't tried it myself, and using soep as a surfactant doesnt seem to
make much more difference.
I will try it again this month, while the saps flowing.

I tried spraying it with both a soap and metho added to try to get through
the waxy coating. I also tried dabbing this mix on cuts too, although I
couldn't vouch for it getting on a cut within a 5 second time frame. The
blackberry and tree killer does work but it also takes a fair amount of time
and I mix it at a higher dose rate than is recommended. Trouble is, the
patch is so big that I can't do the whole sodding lot at one go and by the
time I get back to it, a lot of it has regrown. There are certainly
disadvantages to having such a big garden.........
