Bill is right - Glyphosate is the
active ingredient in the product "Rodeo" used for aquatic weed control.
Now keep in mind, this is the same active ingredient used in "Roundup" - used for weed control in landscapes.
The difference is a legal one - one labeled for aquatics one for non-aquatics.
Those who do this commercially must stay in compliance. I don't see why a homeowner couldn't use Roundup in an aquatic application though as long as they follow the "Rodeo" label as the active ingredient is the same.

Keep in mind....there is a % of Glyphosate listed (53.8% in "Rodeo") and since the patent protection ran out on Glyphosate it has been produced in various % offerings from both Monsanto as well as other companies such as Ortho, and several others.
Always check the label - specifically the list of active ingredients on a product before purchasing.
Also the use of blue dye will help control algae and other pond weeds so keep that in mind - these dye products are available from several companies...
