I have a small pond that is a real PITB to use for training because of the watershield that takes over every summer. It's not a big pond, but it's water. It has a few fish as well that my hubby would rather not kill off. We've looked into granular 2-4,D and that seems to be the way to go. However, I know there are folks here who have a greater knowledge of pond maintenance and I was hoping to get an idea if there is a brand of 'weed killer' that would be 'best' or most efficient.

We fought watershield in a few training ponds that had completely choked them out. I mean you couldn't even see water the ponds were so covered. Pretty much made the ponds useless in the summer for training. We had excellent success with Navigate Granular. Treated in late spring just as the watershield was starting to grow. It is expensive but killed it completely and kept it back for several years. Grass crap will eat watershield but it isn't a preferred plant for them. They could possibly help maintain new growth (if you have any) once you've knocked everything back. I did a ton of research a few years ago. Just my opinion - Use navigate and get back to training. PM me if you want more info.

KARMEX® DF HERBICIDE

Very effective in controlling pond weeds. It is also illegal to use in most ponds.

NOTE: Do not use in domestic water supplies. Do not use in ponds and dugouts producing fish
for human consumption. Do not use water from treated ponds within one year for irrigation; do not
apply to ponds having desirable trees or shrubs on the perimeter, or to areas where their roots
may extend, or in locations where the herbicide may be washed or moved into contact with the
roots; do not drain ponds into areas containing desirable plants as injury to the plants may result.

Thanks all for the info - we tried glyphosate with poor results - the watershield just came back stronger, even after multiple treatments in one growing season. And we tried grass carp which also had no effect ---- time to get a bigger hammer.

will definitely look into the above mentioned products.
Thanks again!

With copper sulfate start in the spring before there are too many weeds. Killing a large amount of vegetation at one time can cause fish kills due to lack of oxygen.

Some states may require you to have a pesticide license to apply certain aquatic herbicides. As noted above, also be aware if the water runs into any other usage areas (ie irrigation). Glysophate is likely going to be most cost effective although control will likely only last for that season as it kills the immediate plants but anything it doesn't get, or anything that is resistant to glysophate will grow through this. 2,4-D will have a slower kill but a bit most lasting power although some plants are building up resistance to it as they are to glysophate. Some states have allowed the use of Diquat, Imazapyr, and Triclopyr. Those will have a longer "lasting" effect but some are restricted use. If you go into your local chemical supply company (my area we have McGregor but back in the midwest we had VanDiest), there are specialists who can help with making some recommendations for you. And if they are restricted use, they can even make a recommendation on who to hire to come out and make the application.

I have always had to deal with Algae/Primrose/Hydrilia

SePro is a manufacturer of Fish/Wildlife/Animal safe products. Below is a link to their website. I might also suggest using their product,Sonar RTU. It keeps you from having to always do a massive kill or treatment for seasonal outbreaks.

Their website has plenty of info and their tech department is excellent. Remember treatment can only begin when the water starts to warm. Good Luck.

I’m fairly sure Sonar is the proprietary name for aquatic glyphosate, same product costs more.

They are tough to kill. I spent 10 years fighting them at Bert Carlsons Retriever Grounds when I lived there and had no success. I used everything mentioned above and never got the upper hand. Cutting them makes the biggest immediate change then spraying after you've removed as much as you can.

I believe that is what Gonia used on his ponds. Fish stayed alive & ponds were bare of vegetation.

So OP your getting a jump at getting water ready.
Not sure where u live however some of the suggestions above will require a license to buy and use in some states.
If the pond is just downstream from a fertilized hay field or u have livestock just upstream it will be a yearly battle. Fertilizer/ livestock puts out atrizene and that feeds the plants.
Trilophy or roundup Will do most of the job , perhaps a coloring agent will reduce the light to the pond. An alternative is grass carp and I add those also at about $6 each. If u have a severe growth consider about 20 per acre to start.
I keep up about 30 acres of water in the south. There’s always something growing that presents a challenge.
I could help with your mix rates if that’s needed
I don’t get growth starting till mid May so u have some time. Remember big leaves are easier to hit ( spray) than small leaves.
Good luck

'Tobias':
Here is your chance to make a difference in the world. Develop a dog breed that munches down/mows pond weeds. Every retriever trainer will want at least one as will golf course grounds managers. Maybe even state fish and wildlife departments. If you call the breed Pond Doodles that will add extra value. :)

Juli, I can definitely vouch for the fact that Dave's ponds look great. He can probably help you out with yours, if you want - Paul

Yes I meant Atrazine - me bad! Being from Bama I was lucky to get that close. And particularly tonight as tailgating started early.
Go SEC !!
