Glyphosate
As mentioned in previous articles, glyphosate herbicides specifically approved for water works well with aquatic vegetation removal. As a systemic chemical, glyphosate works its way throughout the entire plant, roots and all. Approved by the EPA, glyphosates are the general go-to for water use, as it does not persist in the environment and is considered generally safe for fish and wildlife as long as label instructions and proper dosages are followed. Aquapro, Refuge, Aquamaster, and Rodeo are popular liquid glyphosate brands that are approved for water use.
