This is a rooted submerged plant which breaks loose from the bottom to form floating mats. In the summer it seemed to have more small "sac" looking structures, now it has black nodules. In some areas it is growing from 8+ feet of water. I'm located in South Georgia. Cant find a match on tamu site or anywhere else. Thanks
I think your right Kelly. Now that we have established an ID, I have a few more questions. TAMU site says that Bladderwort is an annual, so in theory it should completely die and start to regrow in the spring? Well it is almost January and the stuff is still growing quite fast. When can I expect it to die, if at all?
It will come back in the spring. Unless we/you have a harsh winter, it only slows down for a few weeks. Diquat and copper, multiple treatments per year depending on water clarity. Fluridone for sure. Grass carp 20/acre.

nice work fellas. I would recommend grass carp as best longterm option. There are many bladderworts that are diquat resistant. We have had success with navigate (2,4-d ganular) if diquat and copper combo not work.
I fear that this strand of bladderwort may be somewhat resistant to the diquat/copper brew, so the 2,4-d may be the way to go. Question for Greg, have you had any luck treating bladderwort this time of year with 2,4-d. I think most 2,4-d labels want you to treat when the water is 65 degrees plus. Also, what's your favorite generic brand of 2,4-d granular?
SAS - Roughly how large is your pond? What is the avg depth? What % of the pond would you estimate as infested with bladderwort? Lastly, are any other plant species present (desirable, or otherwise)?
1.25 acres, avg dept 5ft, no desirable vegetation, secchi dept 3-4 ft, alkalinity 120ish, moderate hardness, ph 6.7, and no infow/ outflow. Treated with diquat copper back in July for sago pondweed and bladderwort took over 2 months later. Haven't treated again yet but have dyed it to slow it down a little.
How much of the 1.25 acres is (or will be) infested with bladderwort? 5%? 10%? 25%? More? Also, I'm guessing the previously treated sago will likely return this spring.
I suggest not treating until next spring. Don't know a generic but we use/sell Navigate. Do you not want to try grass carp? If 1.25 acres 15 grass carp might rid of all vegetation then add back in some artifical habitat if needed.
Grass carp will be a serious option. Any luck with a liquid 2,4-d injected beneath the water surface? I know it's much cheaper than the granular, but I have heard some horror stories about severe wind drift. Any thoughts?
There is about 25% coverage in the pond. Mostly scattered patches. Would the treatment rate of Navigate be based on total pond acreage or could I spot treat the affected areas only? These affected areas are mostly in the center of the pond rather than on the banks.
