Glysophate and water

[LMan1967]

Is glysophate harmful to fish? I need to spray weeds around my pond, but dont want to hurt the fish.

 

[rasimmo]

I think it may be. There are some aquatic weed control chemicals I have seen. They were pretty pricey though.

Glysophate is not harmful to fish. But some of the surfactants included with some formulations are.

see here >>> http://www.epa.gov/oppsrrd1/REDs/factsheets/0178fact.pdf

"... Glyphosate is no more than slightly toxic to birds and is practically nontoxic to fish, aquatic invertebrates and honeybees. Due to the presence of a toxic inert ingredient, some glyphosate end-use products must be labeled,
"Toxic to fish," if they may be applied directly to aquatic environments..."

thanks for the info :thumbsup:

There is a Roundup, (glyphosate), product called Rodeo that is formulated to use around ponds and water. Like Hoss said, normal glyphosate solutions have surficants in them that are the bad things to use around water. Rodeo does not have those chemicals and is safe, (approved), to use around your pond.

Do a Google search for "Rodeo herbicide", to learn more. It is more expensive than the normal Roundup, but made for the job to use around ponds and water.

FWIW, I just sprayed some roundup around my 3000gallon goldfish pond about 2 weeks ago. The fish are still alive.:thumbsup:

I did use care and tried not to get any in the pond. But I amd sure some found its way, but not much.

I tried to control cattails in the pond. Finally gave up and sprayed them with roundup. Didn't seem to bother the fish at all.

I use a weed whacker. No way I'm going to get glysophate or any other chemicals near our pond since that's the source of our drinking water. Many of these chemical companies say their product is safe for drinking water. In my opinion that's BS!

SHORE KLEAR from TSC is made for aquatic use, and there are others. That said, the plant problem will reoccur until you remove the favorable growing conditions for the plant you want to eradicate. Water depth and slope of the bank need to be changed.

Also, there is a lot of good information at PondBoss.com.

Can't add much to the good info so far, other than agree:

The 'soaps' used in regular roundup/ generics are not approved/ so good for pond critters long-term.

There are special formulations of glyphosate (roundup) that are approved for pond use - the glyphosate is the same, but the 'soap/ part is different. Rodeo is the most well known, I think there are also cheaper generic versions.

You have chemical phobia... Also known as ignorance. Here's some fact.. no BS. All materials are chemicals. Salt is a chemical. Oxygen is a chemical. How a chemical affects a person is a combination of amount, time of exposure, toxicity and that person's sensitivity. Even oxygen in excess is toxic. see here >> Oxygen toxicity - Wikipedia, the free encyclopedia


A few onces of glysophate in a million gallon pond doesn't concern me if it were my water source. But you're free to use your weed wacker while spewing carcinogenic gasoline, oil and various combustion products into your drinking water

How well did it work on the cattails??

I have had good luck with glysophates on water weeds. Just need a little bit on them so there is no sense in drenching the plant and putting more in the water.

Different strokes for different folks. You are free to gulp as much good ol' Glyphosate as you wish. Good luck with that.

Any chemical should be used with care, but according to the EPA over 700ppb is too much in your water and according to them it would take years of drinking too much in your water. A little overspray shouldn't hurt anything in the water, but as previous posters have said it isn't the glyph. as much as the other stuff with it. Read the label and go from there.

I don't let my chickens out on the day I am spraying so I do believe in taking precautions but a little overspray wouldn't be gulping.

I have a 2 AC pond and had weeds all around the edge of the pond...too dangerous to try and use the tractor ...so I used the Round up imitator from Home Depot on line only..called " Compare and Save " that is the brand name and is 41 % Glyphosate ---So I used a pump up sprayer and carefully sprayed a mist of a spray on the weeds all along the bank...sure enough within a week or so all the weeds and grass were dead..that was last September and they are still dead...it is supposed to kill all grass and weeds for a year and I am a believer...No harm to my fish...at least I have seen none floating and we still catch them....

Wow, I had the exact same thought today while I was mowing around the tank. Very tall Dallis grass about 3-4 feet next to the water that I can't mow. Its a LONG way around that thing to have to weed eat it.

Like most folks I used pesticides such as glysophate, 2, 4-D, surflan etc for whatever purpose I needed. That was the norm for me until I got my Pesticide License. The training I've had over the years taught me to only use the pesticide in the manner that the label states. Here in Texas the label is the law. One of the points an instructor made to me hit me really hard. If the label said use 2 oz I would always use 4 oz so it would work better, his point was if you needed 4 oz the company would say use that amount so they could sell more. That was me, always using twice what the label called for. Or applying pesticides that were not labeled for that application.

I would agree with the previous poster when he suggested Rodeo or another aquatic labeled pesticide. In Texas you are required to have an aquatic category on your pesticide license to legally spray in and around water.

I understand and know that lots of folks use roundup around ponds(I used to be one of them myself), and that it does what you want kill the unwanted plants. And those folks will continue to use roundup because it does kill the unwanted plants. Still doesn't mean that there isn't a more suitable product out there for that purpose.

Sometimes knowing the law isn't a good thing, sure makes me more cautious and boring.

Having a pesticide license or going through the training makes one more aware of what the pesticides can do and what companies have to go through to get a product licensed. Knowledge is never a bad thing.

The LD 50 of glyphosate is very low for animals. As with any pesticide, just use it properly and you will be fine.

With gly more is not better. A higher concentration solution will cause the gly to be absorbed too fast and will kill just the top of the plant, not allowing the salts to get into the roots for a good kill. I found that out the hard way, then read up and discovered why my spraying did not work. The label solution amounts are accurate for good results and I now mix it exactly as it recommends. And it saves money and time.
