ALLIGARE Diquat Aquatic Herbicide, Diquat Dibromide Aquatic Herbicide, Clear liquid

This browns up water lilies (and watershield and cattails) extremely fast! Much of my shallow waterfront area gets covered by water lilies and watershield as the summer progresses, making the water look bad from a distance, and making boating hard. I’ve used IMOX in the past with good results - it kills the roots wen applied late in the season - but when I applied some earlier this summer, I couldn’t see that it did anything visible to the water lilies. Then I mixed up some of this Diquat in a tank sprayer at 2 - 4 oz/gallon, plus some surfactant, and sprayed some of “my” lilies. In 2 hours, all of the lilies that I had sprayed were turning brown. Same thing on some cattails near my dock. This stuff works!

This stuff is a beast it kills everything... it will kill hydrilla but you have to stay after it.

ive used this in pond to kill submerged weeds and it kills them within a day .for killing weeds in yard it kills them in a few hrs this stuff is the best but be careful !

Instructions not easily readable but the product dies the job on water grass and weeds

Less expensive than other brands for the same concentration.

100% It is what it is Kills Duck Weeds !! 30 minutes within the first spray . I would recommend it over all . Sprayed 3 weeks ago and pond is clearing up so nice ..Did not harm my ducks or fish.. Thats a plus on my part as you see they and pond are Happy

Oh. My. Mercy. This stuff is like manna sent from above when it comes to controlling lily pads. Let me start by saying we have done everything we know to control the rampant water shield in our 5ish acre pond. We’ve spent thousands on Navigate, used RoundUp mixed with Ajax, and even gotten in the pond and pulled them up by the roots. Nothing, and I mean NOTHING has worked as fast or effectively as Diquat. I knew that it worked by disrupting the plant’s photosynthesis ability, but I didn’t realize how quickly that it would take effect. We sprayed it early in the morning and by that afternoon the lily pads were already dead—no lie. I walked my little self out to the pond thinking I would take some “Before” pics before the chemicals really took effect, and I about fell out because the lily pads were already brown. By the end of the first week, they were turning loose from the bottom and clumping into floating masses of dead lily pads. We did get in the boat and scoop those out, and I could see more dead lily pads stems still holding on. Here’s how I mixed and applied, and I’m quite certain it isn’t right, but it worked: I applied in early May, just as the lily pads were blooming and before they developed their natural resistance to herbicides (Look up research on the gelatinous covering that they develop as it gets warmer). I mixed an entire gallon of Diquat with a full bottle of Ajax (for surfactant) and plain water in my 15 gallon sprayer. I had that hooked to the truck’s lighting system and just spot-sprayed, only focusing on one area of the pond. And that’s key, because the Diquat wound up spreading to ALL OF THE OTHER LILY PADS—even the ones we didn’t spray. The lily pads we didn’t spray died just as fast as the ones we did. That’s my one caution...be sure that you only spray this on and around the stuff you want to kill. There were even a few areas of overspray on the pond’s dam that i accidentally turned brown. I believe the proper mix rate is 32 oz per 100 gallons, but please don’t quote me. I did have trouble determining the mix rate for broadcast spraying in water. I found a cheat sheet on North Dakota State University’s website that helped me understand mix rates a little more. Next time I’ll mix it appropriately, but this stuff worked so well I’m hoping there isn’t a next time.

Best weed control ever
