Pond experts - what is it and how do I kill it?

[Lloyd Smale]

Im in the process of trying to kill mine. I used http://www.ebay.com/itm/251776342997...%3AMEBIDX%3AIT It is killing it but ive had to spray it a number of times. I don't know if it would have killed it the first time or not. It didn't appear to killing it all but I only let it go 3 days. Ive now sprayed it 4 times over a 2 week period and its about 3/4s dead and most of the remaining leaves have black spots on them so they will probably die soon. I know I sprayed round up on it many times and it didn't touch it.

The stuff in the lower right corner is just rotten stuff that tends to collect on the edge of the pond. Mostly old grass.
Thanks for the tips and keep them coming

Grass carp are the only long term solution. No chems to buy over and over. They will eat it all. Ours eat the grass clippings when we mow around the pond.

[snowwolfe]

I am new to the pond stuff. Any suggestions on where to pick up a couple grass carp?
Or will poi do as good of a job?

[bearcove]

Grass carp. Find a place that sells bait. They will have them or can tell you who they get bait from.

[Alvarez Kelly]

Grass carp will certainly do the job, but make sure get the sterile "triploid" variety. Grass carp get real big. Once vegetation is picked over, they will eat anything. I have caught a 32" grass carp on a worm. I have seen them over 4 feet long. These fish can reduce your ponds holding capacity for your preferred sport fish.

Something to consider...

There are many species of pondweed and that appears to be one of them. Tripod grass carp at 5 per acre will certainly help long term.

If you want to kill it, 2% glyphosate with a good surfactant like Inergy will work. If you add 0.5% Imazapyr it is a death ray on every emergent aquatic plant but water primrose. Killing any weeds this time of year poses risks due to oxygen depletion. It is best to treat only a portion of your pond.

That is definitely not hydrilla or some other invasive species. It's actually good habitat as long as it doesn't pevent fishing.

Anyone feel free to pm me with questions.

I'd do it old school. A piece of chain link fence and some angle iron welded together. Strap fast a cinder block or two for weight. Get several hundred feet of strong rope and attach it to the device.

Put it on the shore on one side of the pond (sunk to the bottom) and take the rope to other side of the pond. Use a truck, tractor or winch to pull the drag you made across the bottom of the pond. Repeat until you removed what you want. No chemicals to buy and the drag is reuseable for decades. This is what the rod and gun club I belong to does to keep their big pond clear. You could even compost the weeds and spread it on the garden.

And they are good eating, not as bony like native carp

I am completely appalled that one our more intelligent members here have not suggested the obvious solution…

First, you put a snorkel on your John Deere riding mower…

Up until all the rain that Texas had recently, the ponds in my neighborhood had been dry for so long that we were having to *mow* the bottom of them. They *used* to have fish in them, but well before the ponds completely dried out, the fish died (overheated or lack of oxygen in the water probably) and really created a "special" aroma for the neighborhood.

Its called the desert SW means it gets dry. sometimes.

Yep, my deer food plot got flooded, so I stocked it with some fish. It's a pond now (tank if you are in Texas), but for how long? Was also using it for a 4 wheeler fun zone.

I believe that is a type of pennywort though it is hard to determine size from your photo. We have a type growing in the lawn. They are edible. I put a few of the lawn variety in my salad occasionally. The water variety has a longer stem. There is a video on youtube by a poster EatTheWeeds on pennyworts and it covers the water variety as well. That man goes by Green Deane and he also has a website www.eattheweeds.com. Search pennywort. As mentioned there are three types. If it isn't one of those this eat the weeds fellow probably has it on his site or in a video anyway and you will know what it is.

Stock answer:

"There is no problem sufficiently complex that it cannot be resolved with the judicious application of High Explosives...."

In your case... your pond becomes weed free... and bigger.

[BrentD]

And dry...

[Old Ironsights]

Ponds re-fill...

And you get a bunch of fish too... you just need to pick them up off the ground.

Win Win...

I like the other version of that saying:

"Most problems in live can be solved by the proper application of either high explosives or penicillin."

[BrentD]

Or alcohol.

[Old Ironsights]

Or alcohol.

Preferably 99%+ mixed with nitromethane and ammonium-nitrate prill and aluminum lake...

Makes a nice Lake at that...
