Potamogeton

There are several species of potamageton in South Carolina. plant branching is alternate. The stems are thin, long and highly branching with leaves very thin and filament-like, about 1/16 of an inch wide and 2 to over 12 inches long tapering to a point. The leaves grow in thick layers and originate from a sheath. The fruit is nut-like 1/8 to 1/4 inches long and 1/10 to 1/8 inches wide.

Submerged portions of all aquatic plants provide habitats for many micro and macro invertebrates. These invertebrates in turn are used as food by fish and other wildlife species (e.g. amphibians, reptiles, ducks, etc.). After aquatic plants die, their decomposition by bacteria and fungi provides food (called “detritus”) for many aquatic invertebrates. Sago pondweed is an excellent food for waterfowl, which eat both the fruits and the tubers.

 

Herbicide Management Options:

 

Sonar: Is a florid one compound and comes in a liquid formulation, and have been effective on sago pondweed. This is a broad spectrum, systemic herbicide. Systemic herbicides are absorbed and move within the plant to the site of action. Systemic herbicides tend to act more slowly than contact herbicides.

 

Reward: is a liquid diquat formulation that has been effective on sago pondweed and is very effective if mixed with a copper compound. It is a contact herbicide. Contact herbicides act quickly and kill all plants cells that they contact.

Biological Management Options:

 

Grass Carp: will readily consume Potamogeton. Grass carp stocking rates to control sago pondweed are 20 fish per surface acre of plant biomass. In South Carolina, only Triploid Grass Carp are legal and a permit from the South Carolina Department of Natural Resources is required.  AMS is licensed to provide these permits for you.
