Will Catt Plex kill algae?


Catt Plex is a glyphosate herbicide labeled to kill shore and emerged aquatic weeds such as cattails all the way down to the root as well as thousands of grass and broadleaf weeds in turf, but will not target algae. You may consider using Crystal Blue Copper Sulfate which controls most species of algae like filamentous or string algae with very low concentrations of copper sulfate.  Please refer to the product label to confirm it can be used in for your treatment area, and for complete application instructions.
