Spraying duckweed with diquat 

Good luck and remember to spray 1/4 to 1/3 at a time to avoid depleting the oxygen in the water and harming fish.

You’re welcome and I hope it turns out good for you.

I really cant recall. I didnt have to take that route after the diquat but I remember reading about it. Just can’t remember where. Apologies and best of luck

Last question…. Did you use the Diquat straight or did you mix in a surfactant to improve performance?

@@hansoncc2 surfactant but cant remember which one. I bought both off Amazon

I want to say it was .75-1oz per gallon and I bought a quart off amazon with a small container of the surfactant. If you have fish in there, only spray 1/4 of you pond at a time with a pump up or back sprayer and wait two weeks. If you have an aerator you should run it more than normal if you have fish in there. Apply like you apply round up. No need to try to cover every square inch. You should see it start working within a week. the duckweed on my pond starting turning within a few days. My pond is about 8700 sq ft. and very little fish in there. Let me know how it turns out for you and hope this helps.

@@HB-kp6rl It definitely helps. Thanks a bunch. That's the first straight answer I got lol

@@nathane55 No worries. I was in the same situation as you and glad to help out.

Yes. Give it a month or so before you do anything else

@@HB-kp6rl I had a plan was diquat kill before winter after that use the grass carp fish to help maintain would that be a good idea cause this is my first doing this

@@carlmarcus01 I have no idea about the carp. I was looking installing an aerator and treating the sludge on the bottom of the bond if the diquat worked. And it did. Once its all gone it’s much easier to maintain. Just spray it again once you see the green haze of the duckweed starting to form and youll be fine
