Welcome McDaddy..... I am from West Tennessee also..... From the pictures this looks like a farm pond, what is the size of the pond, do you have any pumps or filtration, what kind of fish are in the pond and where does the water to maintain the water level come from..... A well or runoff from the surrounding area. Also has that plant always been there but took off this year or did it just appear this year. It takes alot of nitrates to support that much plant life

@McDaddy
Looks like Duckweed to me. Would take a lot of ducks to get rid of that stuff!
Found this on the net about it: https://www.gardeningknowhow.com/plant-problems/weeds/duckweed-control.htm

It is invasive in a lot of states .

That may be Spirodela a larger member of the same family of plants as Duckweed.
Considered beneficial under normal circumstances as it is a veritable sponge when it involves Nitrate and Phosphorus. It can become invasive when nutrient levels dramatically increase over typical levels in a pond.
In your case, I would guess run-off from nearby agriculture or animal pasture.
The only permanent removal is by netting.

i called my county extension office and sent these same pictures
I was TOLD CLIPPER will kill it all.
It will be PERMANENT.
so that is what Im getting

Clipper is a flumioxazin product and comes in a water dispersible granule which must be mixed in water first and then either sprayed or injected. It is a broad spectrum, contact herbicide. Contact herbicides act quickly. Flumioxazin should be applied to actively growing plants and a surfactant will be needed if the herbicide is applied foliage of floating or emergent plants. Water pH needs to be below 8.5 or flumioxazin will rapidly degrade and lose effectiveness.

One danger with any chemical control method is the chance of an oxygen depletion after the treatment caused by the decomposition of the dead plant material. Oxygen depletions can kill fish in the pond. If the pond is heavily infested with weeds it may be possible (depending on the herbicide chosen) to treat the pond in sections and let each section decompose for about two weeks before treating another section. Aeration, particularly at night, for several days after treatment may help control the oxygen depletion.

One common problem in using aquatic herbicides is determining area and/or volume of the pond or area to be treated. To assist you with these determinations see SRAC #103 Calculating Area and Volume of Ponds and Tanks.

looks like duckweed to me , ur pond is extra fertile

Just keep in mind that the action of any algicide or herbicide only releases the nutrients that caused the excess growth back into the pond where it can trigger another bloom be it algae or invasive plant. Additionally as the dead algae or plant decays Oxygen in the water column can decrease to dangerously low level often resulting in a fish kill.
If you do not have ample aeration your already bothersome problem can quickly become a nightmare.

@McDaddy Are you a representative for the company that makes Clipper?

 

[McDaddy]

I own the company

you know

 

[Meyer Jordan]

No algicide or herbicide is "permanent".

 

[MitchM]

??

So you called your own county office to tell you that you needed to use your own product?



That's a new style of marketing.

O goodness

No need for that attitude @McDaddy - your offensive posts have been removed and I'm locking this thread.
