The following site says that roundup can be used to control the poison ivy.
http://www.conservation.state.mo.us/...e/flora/poivy/ The
botanist for the National Botanical Gardens in Washington DC said at a pond
meeting several years ago, that Roundup can be used to control weeds in
natural ponds without affecting the fish and other animals. It is
apparently neutralized on contact with water. I would, personally, limit
the amount of roundup going into the pond, but not be too worried about
minimal overspray. Some insecticides are very toxic, even in small
quantities.

I'm showing off some of the plants I put in at the edge of one of my ponds
and the person I was showing them off to pointed to another plant and
said:
"Uh, isn't that poison ivy?" Now I'm not allergic to poison ivy or any
other stuff like that (I would have known, I planted some stuff right in
the middle of a poison ivy patch, there's no way I could have avoided it.)
so I've never really tried to watch out for it or even learn to identify
it
too well. I Googled up a bunch of stuff on it and the pictures look like
it so I'm pretty sure that's what it is and even though it doesn't do
anything to me it still creeps me out. The past few weeks I've been
looking around for it and have found it only in three places.
Unfortunately they are at the edges of ponds and places that I have bush
hogged recently. I've bush hogged lots of other places where poison ivy
has not sprung up so I don't think the bush hog is infected or anything.
I
do wonder if I am creating especially inviting places for poison ivy (and
if so, how to avoid doing it) by creating tree/pond/grassy interfaces.
What is the best way to get rid of what I have growing? I took a squirt
bottle of Round-up (tm) to it and then thought that Round-up might not be
the best thing. I'm not really opposed to the "Kill them all, let God
sort
it out" theory of scorched earth weed killing, but there are a bunch of
neat little critters that live in those ponds and I'd really hate to screw
up their home. Short of digging out individual plants by the roots (I may
resort to that) is there any kind, gentle way to kill the evil weed?
