Tsunami DQ Aquatic Herbicide - Gallon - 37.3 Percent Diquat Dibromide - Concentrated Aquatic Weed Killer for Lakes and Ponds - Duckweed, Watermeal, Curly Leaf, Pondweed & Many More

We live on a 2,000 acre lake in North Central Florida. Our property has a 600 ft long, 40 ft wide private canal that leads into the lake. During the first part of this year, we experienced a drought that caused the lake level to drop with evaporation. This was the lowest we have seen the water. The low level of the water in the canal spurred crazy growth of weeds its entire length. It was mess that we were concerned as to whether we were going to have to hire a crew to manually remove these massive aquatic weeds of all types in this area. In early June, our rainy season kicked in and within a month, the lake was close to normal level and we had a completely unnavigible canal, that was choked with weeds. No way we were getting our boats out. A few years ago, we had a similar, but not as extreme problem. We tried several herbicides and weed killers that were safe for fish and wildlife and never got anything to kill the weeds back enough to remove them easily. We ended up having to hire a $7,500 crew to manually remove them. This year, we made it a quest to find something that would truly kill off all types of weeds in our canal in a rapid manner. After spending literally hours, reading literature, speaking with our few neighbors, reading reviews to see what's out there REALLY does, and viewing countless videos, we settled on a product that we have never used before, nor had we heard of called TSUNAMI DQ. We mixed as directed and applied it to the entire surface of our canal as well as the weeds themselves with 2 powered Backpack Sprayers. The results were astonishing! Within 24 hours of application, Lilly Pads, Maidencane and other weeds were already brown on exposed parts. Within 5 days, 80% of the weeds, even the tough ones, were brown and dead. Today, we are putting one last coat on the entire canal, wait a week, then drop muck tablets all over the bottom because it's definitely going to need them. This is, by far, the most effective product of its type we have ever used. I don't say this lightly. We have tried just about everything over the years and nothing else that we have tried compares. HIGHLY RECOMMEND THIS PRODUCT ☆☆☆☆☆ 5 Stars!!!

The material was well packaged with each jug in a heavy plastic bag. The cardboard box was torn and the tape was coming loose. But everything was protected and sealed and ready for use. The chemicals are the brand name and excellent.

Works on duck weed and other unwanted aquatic growth.

It worked

I use this primarily for duck weed and works great. depending on your infestation, it may take a couple applications. I apply by broadcast.

Product is safe to use

This stuff is amazing. I sprayed my lakefront that was filled with hyacinths! Killed everything!

Whatever this is in the photo, it doesn’t do a thing to it. Instructions say to mix it 1pt/2pt per 15 gallons. I bought a one gallon sprayer and tried 1 ounce per gallon. Waited a week. Then 2 ounces per gallon. Waited a week, then 4 ounces per gallon. Waited a week and still no effect. I then went straight with no dilution and after a week, still zero change. If anyone recognizes what this weed in the picture is called, please post a reply. I can then do targeted searches to get rid of it.
