Since the weed beds are still small, you can try spot treatment with a granular herbicide such as Aquathol Super K. It is getting the time of the year when curly leaf is sprouting from turions for next years production. Or your "crop" in a new pond just got a late start in its growing season. It will definitely overwinter as healthy plants and you will not see a die back this late in the year.
