I wish I hadn't followed that link now!
The idea that rabbits get this stuff dripped into their eyes just so
we can spray a weed or two, safely , is all a bit
much...................

All new commercial chemicals have to be tested on animals by law. The ones
which we use, are those which are the least nasty. (The others never get to
be sold).

It may also be worth noting that ivy is one of the more useful 'weeds' from
the point of view of encouraging wildlife (insects and birds). Perhaps you
should feel equally depressed that the same stuff which proved not to be too
horrible when tested on rabbits, is extremely horrible when used on ivy.
