I saw a study done on the effects of roundup (I believe, one of the weed killers) on frogs... Keep in mind that I'm working from the top of my head, and I'm usually close on stuff like this, and I'll ssee if maybe I can dig it up, but they found something like 50% of frog eggs exposed to it at the "safe" levels described on the label under normal use never even hatched, and 75% of the tadpoles that did hatch had birth defects, many of them not making it past the tadpole stage, those that did having a high incidence of leg deformities.
This, I believe, is not good. Anyway, I'll see if I can figure out where I saw that study and try to link it or get some direct quotes or something....

The active ingredient in Roundup which actually kills the weed is isopropylamine salt of glyphosate. Glyphosate binds to the plants enzyme (EPSP synthase), stopping it from producing tyrosine, tryptophan and phenylalanine, critical amino acids essential in the plants survival.
Glyphosate is used in lakes to control weeds but in moderation.
So yes, It will kill weeds in lakes and ponds but only under certain conditions. Glyphosate has a high Koc value, which means it bonds to soil very quickly. So if the water has a high turibidity (cloudy, murky water), it will be absorbed by the floating particles in the water and not be absorbed by the plant, thus not killing the plant. So water conditions of the pond or lake must be clear.
It is considered as a moderatly toxic herbicide and poses no known threat to human health.

NO, NO, NO. Do not use in the water. It will contaminate the water.
I use Round-up frequently, but am very careful never to use it within 100 yards of the lake. Even if you use it near the edge of the lake, if it rains, the runoff could cause some of it to go into the water.
I have been researching contaminants in Lake Champlain. It is beautiful and clear, partially in thanks to the responsible landowners surrounding it, but still has too many pollutants.
Thanks for asking before trying it. I know the weeds can be annoying, but they provide food and cover for the fish.
Good luck to you!

It can be used, but would not advise it. That stuff is lethal and you've got to use extreme caution, especially when fish or animals are subjected to it! Get on the Internet and do some searchin', also ya' can check with a local hardware store or similar out-let for an alternative.

First off as on the label it is not for water use!
Yes it can be used if it is done properly to kill surface weeds and it is easily diluted in water!It needs to be applied to dry weeds and given around 30 minutes to be absorbed but as the label states not regulated for use in water!
So do not use it!

around the edges, yeah. I would not spray it in the lake itself.

Absolutely NOT.....Read the label."Not to be used near water sources...May be hazardous to wildlife"..........
