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?

Hmmm. We are talking about plants here, aren't we? Roundup is an
herbicide, not an insecticide. Just thought I would clarify that point.

==================
And it's very difficult to kill poison ivy with Round-Up. It simply turns
it yellow, some leaves may fall but it's back in no time. Getting the root
to die is no easy task. Someone recommended we try Spectracide's
TripleStrike on it... we just picked some up the other day.

I'm so allergic to it that I begin iching just having this conversation.
My method? Nuke the entire area and ask questions later.

Hi,
What this poster is recommending is illegal. While Roundup may be effective
on poison ivy it is dangerous and as stated above illegal to use on water,
period. When all else fails RTFL. I googled "roundup + water" sans quotes,
and chose these links from 800,000.

Thanks for this information. I suspected it could be dangerous around ponds
and that's why I hesitated to use it on the poison ivy around the pond's
berm. I just looked at the label on Round-Up and all it says is not to
spray it directly on water - no mention of danger to fish or other critters.

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.

The botanist for the National Botanical Gardens in Washington DC said at a

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.

I do not think Round Up is approved for use in and around any ponds
or waters........The companion product Rodeo is supposedly recomended
for use in and around water. Rodeo is used to kill aquatic weeds etc,
and it states how to use it "in" and around ponds etc, but then in its
cautions it says to keep it from getting into thr water.........go
figure. I always use a surfficant with any products I spray as it
makes for all the differences in the world in the plants ability to
hold thre treatment on its vegetation and not run off. Less wasted
product with a surfficant. I take a mop, saturate it, wring it out to
the point its not dripping, and just swab whatever I want killed. Been
doing it like that for years now in and around my pond without any
problems. I even managed to eliminate a lot of water clover and
parrots feather and cat tails this way...........

I don't think Roundup or Rodeo releases any problematic stuff once its
taken in by the plant, so what would have to be neutralized? These two
chemicals kill by going to the root system.......

## 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?

I use Roundup at a rate of 4 oz per gallon and get 99% kill rate. I am
spraying new seedlings that have small roots. If you are spraying a
field with established rhizomes, then you will need to keep at it since
the rhizomes can extend many feet under ground. Unless you spray every
green leaf that comes out of the rhizome (which may extend over acres),
you won't effect a kill. If you cut a trench round the kill area about
a food deep, it will sever the rhizome around your kill area so you can
get a complete kill. If you plow a field of rhizomes, every piece will
form a new plant.

In large areas, mowing repeatedly may drain the rhizomes enough so that
spraying will be more effective or not even necessary.

I should have said many feet laterally under ground. They never go very
deep. When I plant Christmas trees, I pull out long poison ivy
rhizomes. They are usually never more than 3 or 4 inches below the
surface. I am allergic to poison ivy so I wear gloves, long sleeves and
wrist guards. When I come in I put my clothes in the wash and
immediately take a good shower with a strong soap. I seldom get much of
any rash.

$$ Thanks Stephen. No acres of the ivy. It's just a few large plants that
came up around the ponds rock necklace. I sprayed them again today (last of
the Round-Up) and made sure to cover all the leaves that I could see.
They're still a bit yellow from the last spraying. I'm so deadly allergic
to them I find it difficult to get to all the leaves since they are tangled
with the net in places, the English ivy, daylillies, hostas and the other
plants around the pond's berm. I will get the rash right through a long
sleeve shirt and sometimes jeans. :-(

In large areas, mowing repeatedly may drain the rhizomes enough so that
spraying will be more effective or not even necessary.

$$ When we redo the collapsing berm/sides my husband will grub it out by the
roots if possible, and we'll spray, spray, spray since the fish will be in a
1,500 gallon holding pool behind the house - far from the spray. I also
plan to use that landscape cloth to help hold down unwanted plants including
the poison ivy. I should never have taken the advice to make the sides
almost straight as now we have a problem with them collapsing or bellying
in.
