So, what is the best way to treat the roots, so they don't resprout. I
understand that ammonium sulphamate, which was sold as root out has
now been banned.
Appreciate some tips.
Thanks Tim
Brushwood killer available from any good garden centre.

For elder, simply wait till new shoots appear and glyphosate them.
In fact cutting back to the ground will kill it too..have these pop up
all over the place: they don't survive even an annual mowing. In fact
not much woody stuff does.
Actually, very few perennials survive mowing..grass of course does, and
some weeds. Nettles brambles and elder dont.

I have used potassium permanganate for tree stump removal in the past.
I suppose it must now be banned, along with most things that work.

It certainly works. To avoid contamination, drill a few downward sloping
holes in the side of the trunk with a flat bit. Spoon in some chlorate
then plug with a wine cork or similar. Or in the top of course if wide
enough.

I haven't used it for many years because it doesn't translocate like
glyphosate or ammonium sulphamate. We used to do just as you say and the
theory was it aided the burning of the stump later.

It's only necessary to get the chemical into the cambium, so a vertical cut
around the inner periphery dosed with chemical is effective.

That was also the reason for using permanganate of potash. It seemed
to work, because the stumps would smoulder away to almost nothing.

OK, I only saw the stuff in small amounts in chemistry sets and as crystals
for disinfecting, I think it was used in public baths for treating foot
infections. Quite effective with spirit of salts IIRC ;-).
Saltpetre could be obtained in bulk then and the sodium chlorate didn't
have inhibitors in it! How did we survive before terrorists showed us our
errors?

There was also "Gentian Violet" as an antiseptic. It was withdrawn
from chemists about five years ago.

And all they have done is found other ingredients, such as perfume and
hydrogen peroxide ....

Common practice on farms round here is to drill a few 1" holes in the
stump and fill them up with fertiliser granules. In such concentration
it's a toxin, not a fertiliser.

It's what's available to hand, really. I wonder if a fertiliser-ed stump
would burn as well.
