Pond Boss Forums AQUATIC VEGETATION Controlling unwanted plants HELP...Just moved into new house with a pond.

A granular or liquid 2,4-D or triclopyr herbicide would work (Navigate, Weedar, Hardball, Renovate) on a spot-treatment basis.
2,4-D may be state limited-use in AL (require a license), but I'm not sure of that.
Glyphosate herbicides might do fair, but not as well as the others.
