Good value, product works great on pond weeds

We live in a small catch-all cove of an all sports lake. Since everything comes our way we've experienced a weed problem over the last several years that inhibits enjoyment and clogs our both propellers. Simply raking was not getting the job done so I tried this. I still had to rake but the weeds seem to be finally controlled in front of our property after 3 to 4 weeks. Also did a nice job of clearing weeds in our gravel driveway.

A proper mixture of Glyphosate and this Diquat results in a potentially powerful combination for many types of undesirable plants. I learned about this deadly mixture after studying Roundup QuikPro. The Diquat provides quick knockdown to prevent further growth and the generic Glyphosate slowly works its way down to kill the root. I find this particularly effective when dealing with thistles that have already grown and are starting to produce seed heads. Buying in the gallon size brought the per-ounce price to a reasonable level.The reason for knocking off one star is what happened in transport. This is a potent bit of hazardous material that should be shipped properly. The container was sent via USPS, which is famous for its abuse of packages. The foil seal on the mouth of the container had failed and the product was leaking into the cardboard box. Feedback was given to Amazon to relay the notice to the seller. There should be a sturdy plastic leak-proof over-wrap around the gallon container (this was lacking) and much better packing material inside the cardboard box (that part was not at all satisfactory. But other than the leak problem, the product is effective and it may be a good idea to stock up before the EPA finds out just how effective it is.

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!

Diquat is an excellent aquatic herbicide. Just be sure to add a good nonionic surfactant.

Good product at a fair price. Worked great on my pond to meet my needs.

Product came damaged and leaking out of the box.
