  • Duckweed Destroyer to get rid of duckweed fast


Everything that you need to tackle Duckweed head on! 

Creating a "chemical cocktail" that includes Cutrine Plus, Tsunami DQ, and Plex Mate effectively controls these weeds. The ONLY TRICK is you need to kill ALL of the weeds. Leaving any living duckweed or watermeal will lead to regrowth. For 5,000 square feet Mix 32oz (1 qt) Tsunami DQ, 64 oz (2 qt) Cutrine Plus, 8 oz Plex Mate, and 4 gal water. Spray directly on the weeds early of a sunny day.

Package treats up to 5,000 Square feet of Duckweed or Watermeal - Includes 32 oz of Ultra Pondweed Defense, 16 oz of Treatment booster, and 1 gallon of algae defense.  This cocktail is the most effective treatment for duckweed and watermeal.  

Add an additional 32 oz of Tsunami DQ to the package to have enough treatment for 10,000 square feet.  

Note that follow-up treatments may be necessary.  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 brown after 24 hours, apply to the remaining green plants.  



Water use restrictions: 3 days drinking, 1 day livestock/domestic animal consumption, 5 day irrigation. Can be used for fishing or swimming immediately after treatment .

Cannot be shipped to the following states: AK, CA, CT, DE, HI, MA, ME, NJ, NY, PR, RI, VT, WA or Canada
