## Description

Diquat Dibromide Aquatic Herbicide 32oz- Kills Weeds

Review: This stuff really works!! - This stuff is amazing. I have a lake in my backyard and every spring It starts to grow aquatic weeds. Also with the rains in April and May, it makes the water just kind of cloudy and yuck so I mix up a batch of this and it kills the aquatic leaves, but it’s safe for the fish. I also discovered that this stuff is lethal for any sort of regular weed. I was using regular weed killer and it would take a week or so to actually kill the weeds but never really just knock them out. So when I have extra of this stuff from the Lake. I put it on any weed that I want to annihilate. It kills them within an hour or so. I like that because they stay dead. They do not come back from this stuff. It is a little expensive to use as a total weed killer and you do need to have a soap or something so that it adheres to the weeds and you add it in your mixture when you’re using this... You use water, this stuff and I forget the name of what the soap thing is supposed to be called and you mix those three things together and you have your mixture. I get two batches out of each of these bottles. That requires two bottles of the soap stuff. I mix those in a sprayer and I’m good to go! This is good stuff!

### ⭐⭐⭐⭐⭐ works well on duckweed and coonweed
*by T***G on June 15, 2024*

I started using diquat in 2023 my 1 acre pond was 100% covered with duckweed and coon weed coming from the bottom I started treating it in June the results were visible within 2 days my pond has trees on all 4 sides so after reading everything I could find on duckweed I knew this was going to be a long process I would treat my pond every two weeks and since there are no fish I more or less sterilized it by fall it was 95% clear of duckweed and coon weed but since duckweed sinks to the bottom in the winter I knew that some would come back and in 2024 it did but only a small amount I sprayed it in May 2024 in killed most of it but I will tell you no matter what the experts say if your pond has trees around it is the leaves that fall in your pond is where duckweed gets what it get what it needs to grow I'm not sure if you can completely kill it 100% but I have a clear pond now but after going through what I did it was worth the time and money to get a beautiful pond back I had used several different types of products but with duck weed don't waste your money on anything but diquat they do make a product that will clear up the muck on the bottom but it is extremely expensive and has to be used yearly and new leaves fall in every year I decided diquat was my best option.
