Customer Reviews for Diquat Water Weed and Landscape Herbicide

I have owned 3 lakes for 24 years and the only product that controls and kills duck weed is your diaquat water weed herbicide. I mix it with copper sulfate and apply with a diaphram tank sprayer. Within hours the floating green mass turns brown. DEAD I purchase 2.5 -5 gallons a year from Do My Own Pest Control_com and the shipping is fast and free. Thanks for the clean lake.

I have used serveral products for the past 20 plus years to kill weeds in my 14 acre lake. None of those products works as well as this Diquat Water Weed Herbicide! It was simple to apply and works fast. Two days! Some of the large leaf pondweed it took 5-6 days to kill it. Does not hurt the fish, frogs, snails, etc. My lake has never looked so good. Ever! A big part of this product that makes it so great is the broad variety of plants that it kills. Those other products were very selective and took a long time to see the results. Diquat was the final answer for me and my lake weed troubles!

The way this material is chemically structured requires a surfactant be used to be effective. Also it is not very active if the temp is below 70 . So as per the review that may have been the problem. As a rancher and citrus grower I have use 100's of gallons over the years and the only time it was not effective was in low temp or forgot to add a sticker spreader. Used correctly it is very effective. Read the label for resistant weeds. Malva or cheese weed when over the seedling stage is resistant. It is a contact only herbicide. That is to say if you spray half a leaf only half a leaf will die. It does not kill roots. Good top kill in 24 to 48 hrs. great for quick annuls top kill only. round up works slow cost more (about 4X) but kills roots.

I mixed one gallon of diaquat with five gallons of water and from a small row boat I used a hand pump sprayer. I covered about half an acre. The weeds were up to the water surface and at least ten feet tall under the water. After three days the weeds are dying and have sunk below the surface. I can still see the weeds but they look dead. I believe the diaquat has worked fine.

The farmers around me all use this on their corn fields before planting. The next day it looks like there has been a fire. I mix 2 oz/gal of 41% Glyphosphate and add 1 oz/gal of Diquat. I sprayed this morning about 8AM. It's 1PM as I write this, and many of the weeds(especially the broadleafs) are already black and shriveled. Others are definitely staring to blacken. By tomorrow I'll know exactly where I missed.

I was amazed how well this product worked on my milfoil problem. I called tech support and they were great. I couldn't believe that I could spray a diluted amount UNDER water and it would kill the weed. It did at a recommended rate of 6 oz. per gallon of water. I set the pump up hand sprayer at the stream setting and blasted the base of the weeds at a mixture of 8 oz. per gallon. In less than one week the weeds disintegrated. I expected to see a floating mess but I didn't. I ordered 2 quarts at $67 with no shipping charge! I highly recommend this great product and this company, Domyownpestcontrol.com

Diquat Water Weed and Landscape Herbicide is the best weed and grass killer that I have ever used. I first purchased this to control duck weed and parrots feather in my fish pond. It is not harmful to fish or frogs. I figured that if it knocked the weeds down by a fraction that it would be worth the money. It removed all. Whatever you spray Diquat on will die. Within 1 hour you can see burn spots on leaves or grass. Within 24 hours almost every plant that is sprayed is totally brown and crispy. This product will kill horsetail, which I've problems with and other herbicides would not touch. Diquat will kill shrubs, small trees, poison ivy, grass, mint and lilies. Some of the products that I've used in the past have taken a week to two weeks to work on the weeds sprayed. Diquat is fast!!! Again this is the best herbicide I have ever used.

This material did absolutely nothing in my application. I'm only giving it 1- star because this form won't let me make it NO STARS. I mixed it per the label directions for spot applications for use on common duckweed, and after no results tried doubling and tripling the mix with no positive results (I last tried a 10% mix). I used Diquat in its original form and mixture approx. 15 years ago, and apparently they just don't make it like they used to. Back then I would see nearly immediate results with application to common duckweed- I mean you could see the plants turning to white within minutes of application in bright sun. This current material is not nearly as solid in color prior to mixing as it used to be, so apparently it is literally diluted to the point that it is totally useless. This is a complete waste of money to buy it, and time to apply it. I have a little of it left and plan to just apply it completely undiluted just to see if it has any validity as a genuine product at all.

I mainly use this for burning off suckers from trees like Olives and Redwoods that sucker prolifically. Much faster than cutting them every week. Also for chemically trimming ground covers like Ivy and Vinca. It's fast and a little goes a long way. Make sure you use a surfactant. DMOPC has a good price. It's the same thing and a little cheaper than Reward.

We purchased a soon to be beautiful 11 acre home with two ponds and a stream. The property was heavily overgrown and the ponds were completely green. We have clear ponds, and have killed on the grass growing in the driveway. All we can say it this stuff is WONDERFUL and super easy to use.

I purchased this to kill duckweed that had overtaken my septic lagoon. I sprayed it day 1 and by day 2 it was already turning yellow. There were still some green places i must have missed so I sprayed again... I am sure I would not have needed to do that extra application. In the following week all of the duckweed has died as well as the cattails that were growing. I am super happy with he results and this product was far cheaper than others I had looked at.

I applied the Diquat as directed with the additional additve to help the weed killer stick to the coontail for more effectiveness as directed. It did a great job on the 1st half of the lake and I'm doing the 2nd half this weekend. The coontail started turning brown on the top layer and is dieing even more as the herbicide works it's way down the weed. It could stand better directions as to how much water to add to Diquat for mixing instructions. Also, please wear a inexpensive rain suit for applcation as this product is very potent and if it gets on your skin and is not washed off quickly, it really burns or makes your skin break out with soars. But it is sure doing the trick on those weeds. I just hope that they do not come back next year.

I have purchased Diquat Weed Killer in the past to control weeds along a roadside levee.. Diquat is the best weed killer I have found to help control this area.. Just mix with water and in a couple of hours under a full sun, the weeds are alreday starting to turn colors... I mix this product with Rodeo Weed Killer and this tends to work GREAT!!!

Does it kill on contact? Yes. Does it kill quickly? Yes. Does it keep it dead? NO. I did a lot of research on this product but clearly not enough. It does not move throughout the plants, so will only kill parts of the plants that it contacts. I don't know if I just assumed this would kill to the roots or if I just didn't see it stated otherwise. I wanted to control the grasses next to the lake but as soon as it was dead there was new growth. At this point I would be spraying every week and constantly have half dead grass, which is ridiculous. I can't think of a need for a product I am constantly reapplying unless it's for sod preparation so it won't kill new grass. This is not the reason I bought it. Sure, it'll kill grass and cattails, but they will be back, and soon! For such an expensive product I expected more, very disappointed and I won't be purchasing this again. As far as Do My Own goes, shipping was fast, so satisfied all around there.

Use Diaquat to control wigeon grass in my coastal two acre pond. The pond is only about four feet, on average, and one gallons keeps it at bay all season long.

I love using diquat it is a great quick acting contact killer of anything. The last job I used this on was a vacant lot that was grown up to my knees. I used my backpack sprayer and going just a few oz heavier than on the label sprayed the whole lot. I came back the day after and everything was dead which made cutting it with my mower so much easier. Remember diquat is a contact killer so it kills everything above the ground quickly. I use this in my job as a lawn care professional in plant beds, just be very careful where you spray it keep the nozzle very close to the intended weed when you spray.

Diquat is a burn down herbicide that requires a surfactant. When you homeowners say "it doesnt work" that is the first red flag that you either a) did not use surfactant, or b) did not calibrate your sprayer, or c) both! If you are that challenged by the directions on the herbicide label, hire someone to do it for you!

Great product. It works. I applied it directly to our pond and within 4-5 days the milfoil was gone. DoMyOwnPestControl was great. The representative helped me select the right product and instructed me on how the product should be applied. Free shipping is a real bonus. I have to order more herbicide and it is pricy, but it works very well. I recommend this product to anyone who has had milfoil take over their pond.
