Roundup does work on poison ivy. I have been using it for many years.
You need to use a strong mixture and add a spreader/sticker and may need
to reapply. Roundup works best on mature plants that are sending sap to
the roots, since it works by killing the roots. On very tall vines of
poison ivy, cut the ivy off about chest high and spray the lower part.
Poison ivy spreads by the rhizomatous roots and the seeds which birds
spread in their guano.
## And that's how we believe it keeps showing up on our property. :-( We
used RoundUp at 6 oz. per gallon and had about a 50% killrate for poison ivy
in the past. I held cardboard behind it to avoid it going into the ponds
and sprayed what's tangled in the net and net's support 3 weeks ago. It
turned yellow and kept right on growing. Is it possible plants can develop
immunity to weed killers like bacteria develop immunity to antibiotics?
The botanist for the National Botanical Gardens in Washington DC said at
a
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.
It is not neutralized on contact with water since it is an aqueous
solution. It is neutralized with water which contains clay particles.
It is the clay that neutralizes it. It is best to apply with a brush or
a cotton glove over a plastic glove so there is not over-spray that gets
into the pond or hits plants you don't want to kill.
## This way sounds much safer around our fish... thanks! :-)
