Wow, that is one good read. From Cornell University? Thanks John.

You're welcome. ;-)

If you like that, I have several more....

(You've been warned!)

I suppose it's worth mentioning that the URL links to a site which
expects the chemical to be used, among other things, on American
_poison ivy_, not real ivy. It'll still kill real ivy, of course; but
it's possible to justify far more brutal measures for poison ivy than
we might think necessary for poor old _hedera_.

I think some energetic hand-treatment and conceivably some glyphosate
if really necessary would normally be enough.
