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, snip

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.

begin quote "Aquatic Midge larvae are killed in 55 PPM of glyphosate
50% of test populations of a predatory mite was killed by exposure to
Roundup
The endangered longhorn beetle is susceptible to low levels of glyphosate
As little as 10 PPM has been shown to kill 50% of test populations of fish"
