Airmax Wipeout Pond Weed Defense Herbicide & Aquatic Weed Control, 1 Gallon

My 1/2 acre pond has been perpetually covered in duckweed since we purchased the property. After reading a lot of material, this was the first product I bought to try and clear it up. I applied it in the late spring after the pond was already covered with duckweed by mixing it in a sprayer, and wading out in rubber boots a few feet from the shore. I sprayed just under the surface, trying to walk and cover the largest area I could. After a month, I was preparing to come back here and say the product didn't work at all. The duckweed appeared to change color, but was still present on the water. After a very dry year, we finally got a rainfall and that churn of the water made all the dead duckweed sink, and we had a perfectly clear pond the rest of the year and through the fall and winter! I mention this, because some reviewers seem to think that you can spray this in the water, and all organic material will magically disappear in a week. That's not the case. You need to apply early, or be prepared to wait for results. This year I'm going to apply it earlier in the spring as a preventive measure. Yes, the price is eye-watering, but I've decided if it costs $200 a year to have a clear pond, it's worth it to me. 2 YEAR UPDATE: I applied this to an already-clear pond in the spring (late March) and the pond stayed clear the entire season into the winter. The price on this product is gradually increasing each year, so while it is very effective, I'm going to start looking for competitors that use the same active ingredient (Fluridone).

This is the only product I found to actually get rid of the duck weed!

This is a SCAM! DO NOT BUY! I have purchased twice and doubled the application amount as directed in the instructions. It’s does not work or reduce the Algae or Duckweed!!

I would give this product 100 stars if I could. Easy to use and the hardest thing was waiting the 45 to 60 days to see if worked. IT WORKED!!! My 76 yr old husband was able to easily able to apply it to our pond that was covered in lily pads. Worth every dollar.

It works, but it takes a very, very, very, very long time. If you think you're going to spray this stuff in the pond, and within a week, see results, you are going to be very displeased. You are looking at at least four weeks to start seeing results and more like two months to really notice any difference. However, it does work. I had a pretty bad infestation of lily pads and sprayed this stuff on the pond (I have a two acre pond that is very deep on the deep end... Probably thirty feet deep... But roughly 1 of the acres is on the shallow end and around the perimeter, it's no more than four feet deep.... so it was lily pad heaven). This stuff is crazy expensive. I am sure that there's about a 500% markup on this stuff. Apparently, there's just no real market for lily removing a herbicides, so to have you over a barrel.

Our pond is about a third acre and the Lilly pads took it over. We had a professional treat the pond with an oxygen destroyer and yes it did great damage to the pads but it also wiped out a lot of the fish. I decide to try this and two weeks after dosing the pond most of the Lilly pads are gone and the rest are dying off without any fish lost. I see babies all over the edge of the pond. 😀 I had to treat it again after we had several storms which raised the water level. I picked up a half of the amount I originally put in and I see it is working. Our issue is the weeds started coming up in the middle of the pond after the level increase and they went along either the entire shore line. I think it works well but I have the dosage wrong.

Was it worth the money. No. Did it pick up some debris, weeds yes.. and wind washed to shore. I would probably have to do more then 5 times to see a real difference.

TLDR: Used this in combination with Airmax Ultra Pondweed Defense Aquatic Herbicide, Airmax Booster, a 2 acre aerator, and blue pond dye, this combo worked wonders....but it took a while. My mom has a 3 acre pond that had been heavily covered in duckweed for years. It's across the country from where I live so I don't get to work on it often On one trip I used the Ultra spray solution and it killed off the duckweed instantly but only in small patches and the weed would grow right back. I also installed a 2 acre aerator kit but it also didn't do the trick. I was hesitant to use this Wipeout due to the price and mixed reviews but I was all out of ideas. So on another trip I purchased the 32 once, knowing it was under the recommended amount, I wasn't willing to go for the gallon due to its price and uncertainty if it would work. I wanted to see if it had any effect at all. I used everything in combination (Ultra, Wipeout, aerator, blue dye). When I applied the solutions I tried to maximize it by applying around the perimeter of the pond and in evenly separated spots in the middle, similar to a grid pattern. Weeks passed and nothing happened, I left figuring it was a loss. Well about two months later my mom calls telling me the pond was rapidly clearing up and sent me pictures of a beautiful, clear, duckweed free pond. I looked back at the product page and it does say it could take come time, I just figured it would be a slow progression rather than all at once a couple months later. I'm glad this was the ultimate solution for a problem that has plagued us for years.
