Airmax Wipeout Pond Weed Defense, Herbicide & Aquatic Weed Control, Controls Duckweed & Other Unwanted Submerged & Floating Vegetation, Easy-to-Use & Long Lasting, All-Season Treatment - 4 Ounce

We applied 8 oz to our pond which was covered with lily pads and coontail. It took a little while but the lily pads died out and the coontail disapeared. I've used aquatic glysophate and diquat but this product worked better than anything I've ever used Purchased 16 oz of the product this year and treating a fairly large area with it. Will see how it works. Great results last year !!!

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 product for the cost did not work. Still have Lilly pads

Have been battling a heavy infestation of coontail and eurasian milfoil for three years in a four acre pond in Texas. Finally tried the Airmax Wipeout, putting it in at the recommended rates in June (later than recommended) by diluting several ounces at a time in pond water in a 5 gallon bucket and throwing it out as far as possible in several places around the circumference of the pond. Over the next 90 days we achieved about a 98% kill rate. Best the pond has looked in years. The slow rate of kill was actually quite beneficial as our really heavy infestation would have led to big fish kill from oxygen depletion if it had killed it all quickly. I wish I could give it 4.5 stars as the only reason I didn't give it 5 stars was due to the cost. I realize it's several hundred dollars per gallon cheaper than Sonar but I was in the chemical business for 20 years and use a lot of herbicide chemicals growing hay for sale on our ranch and chemicals just don't cost this much to make. Having said that, if the weeds come back next spring I'm buying more Wipeout!

The only product that killed the weeds in my pond. Fish and frogs are still happily swimming.

This is my third year using Wipeout. The treatment has always worked well keeping any plant growth from happening. Even killing the cattails we had. This year I wanted to get ahead of any algae growth so I treated the pond in early March. It's now almost May and there is algae around entire pond about 5 feet from banks. I'm not sure why it didn't work this year , but the product went up in price $120 from last year. That's now $420 to treat a half acre pond. I was reluctant to spend that much, but it has always worked. I do use pond dye which I usually add when I use Wipeout. I didn't use dye this year. Maybe that's why it didn't work. Not sure. Hope this helps.

I honestly am a bit taken aback. I have a 1/4 acre lined pond with a sand bottom. (In hindsight I never would have covered the liner with sand but thought it would do better in protecting it from the deer traffic.) Anyway most recently the Pond Weed and other submerged weeds were taking over closing in the edges to only leave about a 30'x30' circle of open water around the fountain in the center. I have been resisting buying any pond herbicide since they are EXPENSIVE and it was hard for me to imagine they would not be diluted in such a large body of water to do any good. I was wrong... I put the 8-oz batch in about 6 weeks ago simply by mixing it with water and dispersing in 4-5 areas around the outside of the pond (from shore). It did take a few weeks but WOW.... the pond weed has been eradicated as have many of the submerged weeds. Anything actually that get's it's primary water source from the pond water has pretty much died including the longer grasses around the shore (that frankly were an irritation in themselves and something I despise weed-whacking). At any rate I will continue to monitor and i it goes as it's going now I will be putting this in my big pond every spring provided the cost of doing so doesn't go any higher. I also ordered an additional 4-oz kit after having my smaller (15'x12') pond be overtaken by what I believe is Sago Pondweed. As I cleaned all of that out by hand on Saturday I was whistling like Bill Murray in Caddyshack as he made small squirrels out of plastic explosives; knowing full-well my new batch of Wipeout would be showing up today! I recommend it.
