It is important to treat early on a sunny day and make sure that the product contacts all of the duckweed or watermeal that you intend to kill.  If any plants remain that are not turning yellow or brown after 24 hours, apply to the remaining green plants.  Note that follow-up treatments may be necessary when targeting duckweed or watermeal.  

Only treat one half of pond every 10-14 days

Mix proper ratios in a tank sprayer and spray directly on the desired area.

When treating duckweed and watermeal on a warm sunny day, results can typically be seen within 4 hours.

When is the best time to treat duckweed based on water temperature?

The best time to treat duckweed is when water temperatures are around sixty degrees or warmer.  Warmer pond water temperatures make the duck weed plants more active causing them to take up the herbicides more quickly for a better treatment. 

Duckweed on the run

Review by Anita H. on 10 Sep 2022

Our pond was covered in a thick layer of duckweed. The first application (half the pond) got us to the point where we could see water again. Second application has duckweed on the run. This is amazing!

 

Made two applications

Review by Tim L. on 6 Nov 2022

Due to the limitations of my sprayer, I had to apply two batches. But the stuff worked great. It eliminated the duck week quickly.

 

Excellent product 

Review by Phillip S. on 15 Aug 2022

The product worked as it should! Duckweed was brown by the end of that same day. Sprayed in morning of a hot sunny day like instructions had stated. Great product! Would recommend

 

Great Duckweed Treatment

Review by Jeremy P. on 20 Jul 2022

From the ordering process to the instructions this was a great experience. I was a bit nervous when I opened the box to see three different containers but then there were these amazing directions printed out and put in the box with exactly what I needed to do. This took all the worry out of mixing this correctly and made it easy. The results are as advertised and cleared my area up very quickly.

 

Duckweed

Review by Preston H. on 9 Jun 2022

I will recommend this product to others. Duckweed is not all gone due to the intensity of the invasion but will add the second treatment next weekend. I will also say it is the best treatment for PrimRose that I have ever used.

 

Duckweed Destroyer Works!!

Review by Lonnie H. on 5 Nov 2021

I received your duck weed destroyer package and sprayed our pond. One week later it was all dead. I couldn’t be more pleased with the purchase.
I’m not on any social media or I would post it there.

 

Community lake

Review by Frank L. on 20 Jul 2022

I left for vacation for a week and gave my neighbor the duckweed destroyer package to spray on the lake. The lake was almost cover by duckweed when I left. When I came back the lake looks really good. There are some remnants of duckweed but It may be dying.

 

Thank you to the pros at Natural Waterscapes

Review by Chris P. on 22 Sep 2021

The "Duckweed Destroyer Pack" transformed our pond in 10 days.
Just follow the directions. It only took 2 applications. We killed the edges into the pond about 30 feet (that's as far we could get with our sprayer). When that died, the remaining Duckweed drifted to one side. Killed that in the second application. And Voila' !
Before: 100% covered in Duckweed

After 10 days: Zero Duckweed

Great product. Happy Fish, Happy Frogs!
