Pond Boss Forums AQUATIC VEGETATION Controlling unwanted plants How to rid of this

Hello. Enclosed I have a picture of 2 types of vegetation in my pond currently. I was wondering if any of you out there knows the 2 types and how I can rid of them. I want it to be fish friendly if possible, because we eat most of the blue gill that are caught out of this pond. Thank you for your help and information - Jack

Hello Jack.

The floating plant is Water primrose. I'd recommend something like rodeo with a surfactant added into the mix. Rodeo is similar to roundup but is approved for aquatic use. Can't tell what the submerged plant is. Pull some up and take another picture.

I'm predicting the submerged "stuff" is southern naiad with a cap/intermix of filamentous algae, based strictly on the how frequently they occur/grow in this manner. But, as Chris indicated, a close-up photo showing just a few sprigs of the submerged plant-mass is necessary for a positive ID.

Ok. Here's a couple more closeup pics of what I pulled out of the pond. Thank you for your help and guidance in getting rid of this junk. Jack

The pictures are primrose the stuff under it I cant tell. get a pic of it. Rodeo for the primrose works for me.

Neither of your last two photos shows the submerged vegetation. Can you pull a photo a sample of it?
The surface weeds are primrose, and some of the management options have been covered already.

Here's a close up of it on the water. Thank you all for the help and getting a plan of action together to whoop this. Jack

I found the listed ingredients in Rodeo and Roundup to be the same - so switched to Roundup because it was much cheaper - and now that you can buy Glystar that is even cheaper yet. I use it on cattails to keep them in check.

Am I missing something here ?

Just an FYI.... When you take pics of weeds for identification it is easier to see what it is if you lay it on a white sheet of paper or put it in a jar of water.

Only that it is technically illegal to use a product off label and that the carrier for the aquatic version of glyphosate is likely different. The carrier in Roundup and generics could be something that is less desirable or harmful in water bodies. Not the glyphosate itself (the "active ingredient"), but the solution that delivers it.

Using product illegally could incur the wrath (and associated fines) of "big brother". Kind of like breaking the speed limit or breaking other laws. If you choose to do so, at least do so with the knowledge of potential negative consequences.

Using the correctly labeled product is likely the best route, after all possibilities are considered.

Edit: If you have lots of it, don't kill off large amounts all at once or you could have a fish kill by having too much decaying vegetation in the pond all at once causing a DO crash. Kill it off in sections at a time if you have lots of it.

Here is the submerged plant. Hopefully I pulled enough. Thank you all of you for the help

Jack,

The plant we are wanting a picture of is the dark green plant that is totally submerged at the top of the picture in your first post. All these other pictures are of Water primrose.

I'm beginning to think that he's Jacking with us.

I think I got what was needed involving the submerged vegetation. Thank you for your help and ridding of this problem. Also, once I start killing all of this off. Should I remove the primrose and the other vegetation once it starts to die or when it dies.

Thank you Jack

If you can, removing it will do two positive things. First it will remove what will ultimately become muck in the bottom of your pond and added nutrient load. That is helpful long term. Also if you do too much of it at once the decaying material uses oxygen and it can cause an oxygen crash which can kill fish. That will help short term.

If you are doing lots of it (significant portion of the area of the pond) and can't remove it, it is suggested to do only partial areas at a time so as to avoid a DO (dissolved oxygen) crash.
