Duckweed Destroyer™ Package

Everything that you need to tackle Duckweed head on! 

Creating a "chemical cocktail" that includes tank mixing 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, watermeal, or mosquito fern will lead to regrowth. 

This cocktail is a fast, effective treatment for duckweed, watermeal, and mosquito fern.  This is also an excellent choice for dense aquatic weed growth (see list of affected weeds below).

Use to manage aquatic weeds and algae growth at the same time.

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 turning yellow or brown after 24 hours, apply to the remaining green plants.
