Just wanted to provide some follow up to my earlier post. I actually elected to go with the Navigate granular product initially to see if it willl have any effect - it it doesn't work I am going to scale up to the liquid products you all recommended. Honestly the granular is just much easier for me to apply and the product warnings on the liquid product kind of gave me the heebie jeebies...

Good news is the Navigate does seem to be working - not 100%, but definitely having an effect. I applied about 3 weeks ago. Other good news is I have small bass and bluegill making beds in portions of the pond that were previously choked out with water shield which is exactly what I was hoping would happen. Thanks for all of the help and good suggestions!

I was out at the property this past weekend, I am not 100% sure yet but I may be starting to see some color change. I will check again next trip. Looks like rain most of the week so it won't be until next weekend so that will be 3 weeks since spraying.

I thought I would see a bigger difference after 2 weeks to be honest but will give it more time.

i found that Navigate worked slowly until the water temp got into 70s - then it worked all over the pond - even where I hadn't placed it.

Well the watershield is slowly dying off where I originally sprayed. I went ahead and sprayed the next 1/3 of the pond but added a bit more chemical than the last time. I re-sprayed what was left in the first area just for good measure. I took some before pictures this time so I can really tell how effective it is. I should have done that the last time I sprayed but didn’t think about it.

Will do, It seems to die off pretty slow so that is a good thing as it won’t decompose too fast and rob O2 from the pond.

The watershield is dying off nicely and our pond is starting to look good again. I will try to resize some before and after pictures when I get a chance and post them in this thread. I still have a bit more to spray but will do it in small sections as it dies since we are already in the 90’s down here and don’t want to have any O2 issues. Thanks for the help, I am feeling a lot better about it now. I have a little over half of it done now and will continue until it’s all gone.

Great, glad all's going well. Watershield can be a tuff one.

Yep it seems to be going well so far. I resized some before and after pictures but the site won’t let me post them for some reason. I’ll try on the computer when I get home.

I tried to post some before and after photos but the file type isn’t supported. My image resize app saves them as a jpeg file but the site wants it as a jpg file 🤷🏻‍♂️

Update on the watershield. On half of the pond the watershield has been elinated and the other half that wasn’t sprayed has died back to about half as much as normal. We got too hot too fast down here so I will treat the other half in fall when it cools off so I don’t have any O2 issues. Most likely that won’t happen until late October though.

Thanks to everyone that had any input into getting rid of it, I think I am on the right track now.

I'm going to let more of my water shield grow back as I'm finding it holds the bass this time of year.

Pulling a creature type soft plastic along the top of the watershield along the bank has been about the only way to catch bass while the sun is bright.

A little bit is good, even a few "islands" of it around the pond gives them edges and cover to hunt from. Too much makes the fishing hard.

The only way to successfully fish it is to horse the bass out or bring the boat into the weeds and hoist them out. It is exciting tho to see them bash the lures tho...

Al, I agree with your approach.

Is Imazapyr your preferred herbicide for watershield? I used diquat as some of the stuff we buy for the farm was also labeled for aquatic use as well. It did a number on them but many came back. They've been around for years so I suspect it would take several treatments to burn them out with it.

Diquat is not a systemic herbicide it just mostly kills the top vegetation on most weeds and watershield thus it just kills the tops and leaves the roots intact thus their regrowth.

So basically anything would be better than it for watershield? lol

Not all aquatic herbicides have the mode of action systemic.
