Diquat Water Weed and Landscape Herbicide

Diquat Water Weed and Landscape Herbicide contains the same active ingredient as Reward Landscape Herbicide, for less money.

Diquat is a fast-acting aquatic & landscape herbicide that kills both weeds and grasses. Agrisels Diquat is non-volatile herbicide for use a as a general herbicide killer to control weeds in greenhouses, nurseries, recreational, commercial, residential and public areas. Diquat controls weeds by interfering with photosynthesis, which results in rapid visible effects in only a few days. Best of all it has a full aquatic label and is not harmful to aquatic animals.




DIRECTIONS

Diquat Water Weed and Landscape Herbicide is a nonvolatile herbicidal chemical for use as a general herbicide to control weeds in commercial greenhouses and nurseries; ornamental seed crops (flowers, bulbs, etc. - except in the state of California); landscape, industrial, recreational, commercial, residential, and public areas; turf renovation (all turf areas except commercial sod farms); dormant established turfgrass (bermudagrass, zoysiagrass - nonfood or feed crop); and aquatic areas. Absorption and herbicidal action is usually quite rapid with effects visible in a few days. Diquat Water Weed and Landscape Herbicide controls weeds by interfering with photosynthesis within green plant tissue. Weed plants should be succulent and actively growing for best results. Rinse all spray equipment thoroughly with water after use. Avoid spray drift to crops, ornamentals, and other desirable plants during application, as injury may result. Application to muddy water may result in reduced control. Minimize creating muddy water during application. Use of dirty or muddy water for Diquat Water Weed and Landscape Herbicide dilution may result in reduced herbicidal activity. Avoid applying under conditions of high wind, water flow, or wave action.

    5 of 5 stars  diaquat aquatic weed control
    By Nick in Martinsville IN on 06/20/2012

    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.

    5 of 5 stars  what it take to work
    By Dennis in Ventura County ca. on 04/11/2012
    Verified Purchase

    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.

    5 of 5 stars  Diquat Water Weed Herbicide
    By Robert in Coloma, MI on 07/24/2014

    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!

    5 of 5 stars  Just like the Big Boys
    By Art in Timberville VA on 07/23/2014
    Verified Purchase

    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.

    1 of 5 stars  Completely useless product
    By John in Terre Haute, IN on 03/19/2012

    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.

  • 5 of 5 stars  Weed Murderer
    By Ron in Jacksonville, Florida on 08/02/2017

    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.

    5 of 5 stars  Best Top Killer on the market
    By Paul in Loganville on 07/25/2017

    I purchased this to kill new woody stem growth and annual weeds that pop up on the wooded border of my property. It kills the green above-ground part of the plants almost immediately, weakening them so they won't grow back. This dispenser is easy to use and accurate. I can mix as little as 1/2 gallon in my sprayer. Using a surfactant in diquat will make the water spread more evenly and kill quicker.

  • 5 of 5 stars  Diquat water weed
    By Jeff in Oklahoma City on 06/27/2017

    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!

QHow do I mix Diquat Water Weed and Landscape Herbicide to kill duckweed in a small pond?

A

For duckweed control, apply Diquat Water Weed and Landscape Herbicide at 1-2 gallons/A + 32 oz./A of surfactant in at least 100 gallons of water. Treatment of dense weed areas may result in oxygen loss from decomposition of dead weeds. This loss of oxygen may cause fish suffocation. Therefore, treat only 1/3 to ½ of the water body area at one time and wait 14
days between treatments. Please let us know if you have any other questions, or give us a call at 1-866-581-7378 since many times with these types of applications, a customer service representative can better explain application techniques.

QWill Diquat kill horsetail growing in a pond?

A

Diquat Water Weed and Landscape Herbicide will kill horsetail. Horsetail is very hard to control and it can be tough to properly penetrate through the plant. When using the Diquat you will need to mix it at the rate of 2-4oz per gallon of water and mix it with an 80% Non ionic surfactant. You will need 2 teaspoons of the surfactant per gallon of water. This combination should eliminate the horsetail from your pond.

QIs Diquat ok to use around a single-family home landscape?
I'm currently using Cornerstone, but some of the weeds just laugh at it and me. I'm mixing it to use with a pump-up hand held sprayer at almost double the recommended strength. Just trying to keep weeds out of flower beds mainly.

A

Diquat is a great herbicide and can be used in landscape areas in addition to its primary use of aquatic weeds in ponds/lakes, however you would need to be careful when you spray it as it would be a non selective and could harm the desirable plants around it. Using a pre emergent like Snapshot or Surflan in spring and fall to prevent weeds from coming up in landscaping and flower beds is the best option. For broadleaf weeds coming up in a flower bed you could use anything like Diquat or Roundup to spot treat, and for grassy weeds a product like Grass Out Max can actually be sprayed over the top of most flowers, ornamentals and vegetables to rid the areas of unwanted grasses.†

QWhat is the rate per gallon of Diquat Water Weed and Landscape Herbicide to kill pennyworts in pond?

A

Per the product label Diquat Water Weed and Landscape Herbicide can be used at a rate of .5-2.0 gallons per surface acre in a sufficient carrier along with 16-32 oz per acre of a surfactant for pennywort.†Retreat as necessary for densely populated weed areas. If you are using it as a spot treatment, you would use approximately .75 oz per gallon of water plus a surfactant. Spray to completely wet target weeds but not to the point of runoff. Densely packed weeds or mats may require additional applications due to incomplete spray coverage. Repeat as needed. For best results, re-treat weed scapes within 2 weeks of the initial treatment.†

QHow do I apply Diquat Water Weed and Landscape Herbicide for Coontail?
Would like advice on Diquat and Coontail in Farm Pond. Fairly heavy infestation. About a acre at 4ft depth. Surfactant needed? Amount per gallon of Diquat? Application method? Using ATV 15 gallon sprayer with wand. Also is it hard on grasses in area near spraying? Some wind drift.

A

Diquat Water Weed and Landscape Herbicide should be used with a surfactant, such as the Non-Ionic Surfactant. The ratio for that product is 1-2 teaspoons per gallon of water. The Diquat can be used as as a broadcast application or a spot spray. It is labeled for various broadleaf weed and could potentially kill them if the product drifts.

QDoes Diquat Water Weed and Landscape Herbicide kill watermil?
I have watermeal that will eventually cover the entire surface of my .5 acre pond. Will this work and if so how much do I need?

A

Yes, Diquat Water Weed and Landscape Herbicide is labeled for watermil, as well as other weeds. It is recommended that you treat your pond in sections as to not deplete the oxygen in the water. The amount of product will depend on the depth of your pond. If your pond is 1 foot deep, you will use 0.25 gallons. If your pond is 2 feet deep, you will use 0.5 gallons. If the pond is 3 feet deep, you will use 0.75 gallons. For a 4 foot deep pond, you will use 1 gallon of products. This is per acre. Since you are treating 1/2 an acre, you will use 1/2 the amount of product per the depth of the pond.†

I live in NY and it is late September. The lake weeds are so thick in our bay. 125 feet x 100 feet. half is 3-4 feet deep half is 5-8 feet deep.

A

Diquat Water Weed and Landscape Herbicide should be applied at a rate of 1 to 2 gallons per surface area of water. For a 1 acre lake or pond - spray 1 to 2 gallons of Diquat into the lake. If using a hand sprayer, for example, 2 gallon sprayer, put 1 gallon of water and 1 gallon of Diquat into the sprayer and spray the contents over an acre of the area. Per the product label, it should be applied in the spring or early summer when the weeds are actively growing  and when water temperatures have reached or exceeded 50 degrees.
