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.

    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  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.

    5 of 5 stars  Watch out weeds
    By Gary in Joplin, MO on 07/05/2015

    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.

    4 of 5 stars  Sucker stopper
    By Rick in Chico,CA on 04/26/2015

    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.

QHow do I apply Diquat to the hydrilla in my canal? Do I mix it with water in the sprayer?

AFor treating for Hydrilla, which is a submersed water weed:

To control submersed weeds, apply Diquat Water Weed and Landscape Herbicide in water at 0.5-2.0 gallons per surface acre (per 4 foot water depth). For severe weed infestations, use the 2.0 gallon per surface acre rate. For best results, re-treat as necessary on 14-21 day intervals. The table below shows how many gallons of Diquat Water Weed and Landscape Herbicide to apply per surface acre based on water depth.
Gallons of Diquat Water Weed and Landscape Herbicide per Surface Acre
                                     Average Water Depth
                             1ft          2ft          3ft         4ft
1 gallon/acre rate   0.25gal    0.50gal    0.75gal    1.0gal
2 gallon/acre rate   0.50gal    1.0 gal     1.5gal     2.0gal
Subsurface Applications:
Where the submersed weed growth, especially Hydrilla, has reached the water
surface, apply either in a water carrier or an invert emulsion through boom trailing hoses carrying nozzle tips to apply the dilute spray below the water surface to insure adequate coverage.
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.

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.

QHow much Diquat Water Weed and Landscape Herbicide do I need? What should be the water temperature? Do I have to wait till spring?
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.

I have a 2.5 gallon of older Roundup concentrate 41% and would like to make the application rain proof by adding Diquat as thunderstorms come up over night without much notice.

ARoundUp products are generally rainfast within a few hours so that is not really an amount of Diquat that we could recommend to make it rainfast any quicker.  The amount of Diquat you use per gallon of water is dependent on what you are treating for.

QBest way to kill and control cattails/reeds and moss in reclaimed water in The Panhandle of Texas
Hello, I have been nominated as the Chairman of the fishing committee. We have a beautiful slightly flowing river and large damned up areas that are becoming overgrown with reeds/cattails etc. the fish are very healthy however during the hot summer months I'm afraid these plants will ultimately overgrown or deoxygenate the water. Could I get some advice please? As always i on a budget. Thank you

A

Diquat Water Weed and Landscape Herbicide is one of our top products for control of Cattails as well as a multitude of other aquatic weeds. It is not harmful to any aquatic life and will control the weeds in the water as well as along the bank.

For Cattails,

Diquat Water Weed and Landscape Herbicide may be applied by backpack, airboat, spray handgun, helicopter, airplane, or similar application equipment that results in thorough spray coverage.
Spot Treatment:
Apply Diquat Water Weed and Landscape Herbicide at 2 quarts per 100 gallons spray carrier (0.5% solution) with an approved aquatic wetting agent at 0.25-1.0% v/v (1 quart to 1 gallon per 100 gallons water). For cattail control, Diquat Water Weed and Landscape Herbicide should be applied prior to flowering at the maximum application rate (8 quarts of Diquat Water Weed and Landscape Herbicide/100 gallons spray carrier) plus the wetting agent. Repeat treatments may be necessary for complete control. Spray to completely wet target weeds but not to runoff. Densely packed weeds or mats may require additional
applications due to incomplete spray coverage. Re-treat as needed. For best results, re-treat weed escapes within 2 weeks of the initial treatment.
Broadcast Treatment:
Apply Diquat Water Weed and Landscape Herbicide at the rate of 0.5-2.0 gallons per
surface acre in sufficient carrier along with 16-32 oz./A of an approved wetting agent. Retreat as necessary for densely populated weed areas. Good coverage is necessary for control of the target weeds. For duckweed control, apply Diquat Water Weed and Landscape Herbicide at 1-2 gallons/A
