My wife and I are moving into a new home on a 2 acre pond. When we bought the lot about 18 months ago, the pond surface was pristine, with only a few cattails, lily pads and other bank based vegetation.



Now that we are about to move in, about 1/4 of the pond is covered in water hyacinth. My neighbor worked for about 2 hours pulling it out of the water in front of his house, only to have it blown back in the next weekend.

Does anyone know if this shite will die during the winter, and the neighbors and I can form some type of coalition in the spring to oppose this virulent intruder? If we were to spray it with 2,4-D and a surfactant now, I'm afraid it would really stink up the whole pond with that much decomposing plant matter.

Thanks.

It sinks during the winter. I hate that stuff.

If I had a problem like that, I would not wait. I would use both chemical and mechanical means. Here's a link that may be of help.

Bookmark the aTm ID site for future reference. I had the same issue on a one acre pond. A pond is almost as much PITA as a pool. Roll up your sleeves and set aside some time to manually pluck it from your pond. It'd be cheaper to hire a couple of teenagers than buy that much aquatic herbicide. If you spray that large amount you could possibly cause a fish kill when it decomposes. Best case scenario is it would decompose and deposit a load of nutrients to feed some other nuisance plant or algae. Once you have it under control you can use aquatic herbicide to kill the stragglers. Tackle it like you would eat an elephant, one bite at a time.

Had some of this stuff in my cattle pond once. Don't know how it got there, but the cattle ate it like candy. They'd clear out a spot in the shallows and when more of it drifted in, they'd eat it, too. Finally ate it all up.

Pull as much out as possible, then spray the remaining bit.
When you get it up on the bank push it in a pile and burn it.

I think there is some sort or weevil that eats it that you can obtain from LDWF or dept of agriculture... I don't remember. My FIL got some for his duck lease a few years ago. Idk how effective they were as it was a very large area...

I am sure they would work well in a pond this size. I will call him and find out...

ETA: sorry it was for giant salvinia...

We had the same problem with a neighborhood pond. We rented a mini track hoe and pulled it out. Once you get it all out you can keep it out with KillsAll Aquatic.
