This stuff is growing like crazy in our pond. Need to know what I can do to get rid of it! Thanks

Looks like something 2,4-d would knock out

Water hyacinth I think.

Google salvinia. Spelling may be off, but it is some bad stuff if it gets in a pond.

Water hyacinth I think.

Yep.

It'll double everyday...

Like compound interest...

Thanks guys, I'm gonna get some stuff to kill this before it gets worse.

Sonar AS herbicide.
I wouldn't put anything in my pond that wasn't aquatic.

Don't spray that with anything that isn't labeled for aquatic application. You will potentially do 3x the damage the vegetation will.

that stuff is called WATER LETTUCE. I work in the business of koi ponds and water features. That as well as water hyacinth is illegal to have for your koi ponds as it's very invasive and can take over natural water ways.

If you have fish be careful spraying large quantities in this heat. Oxygen depletion is magnified.

Looks like creeping primrose. In a few weeks it will bloom yellow flowers.

Looking at it closer maybe not. Sorry I’m no help.

As Takoma correctly said, it is Water Lettuce. Not water hyacinth. Good luck.

[ultrastealth]

Not hyacinth.

Water lettuce it grows every fast spray it with some Roundup custom I deal with it all the time.
