Can someone help me with identifying and management options for an algae or moss that has just arrived on a pond? It is about 1/2 acre worth on a 2 acre pond and spreading. I can't post pics, but will email them or text them if you PM or post your contact info. Thanks in advance.

I'll post them for you. Send me your number in a PM

Looks like water primrose to me. Here is a link to check it for yourself. Can be easily sprayed. Go to Producers Coop and see Dr. Lazby he will solve your problem.

It appears you hava a combination of things. The stuff out in the middle appears like it could be coontail (Ceratophyllum demersum) that is covered with filamentous algae. Both will typically take off after fall rain washes manure and other fertilizer that has built up during the summer months. The coontail and other submerged aquatic plants are excellent cover and provide good waterfowl food either from the plants or invertebrates.

The other poster was correct that the floating leaf plant in the foreground of the pics is creeping water primrose (Ludwigia peploides). Not great for wildlife but good cover.

Rotenone will solve all your aquatic vegetation problems.

Water primrose as far as the floating vegetation around the perimeter of the pond. Seems pretty minimal and is typically of no concern.

For the bulk of what you have, it appears (as a previous poster stated) to be coontail that has filamentous algae using it as a substrate for growing.

It could also be chara (i.e. skunkweed), but hard to tell from the pics alone. Could also be both of them co-mingled with each other.

Coontail is a rootless vascular plant, while chara is a rooted algae, and each would potentially require a different herbicide for treatment.

If you can post a close up pic of the submerged vegetation that has the algae on it, or just see if vegetation in question has roots or not, would help in identifying.

Looks lik skunk weed and ludwigia.
