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.

    diaquat aquatic weed control

    By Nick 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.

    Diquat Water Weed Herbicide

    By Robert 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!

    what it take to work

    By Dennis 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.

    Just like the Big Boys

    By Art 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.

    Curley leaf Pond weed

    By Anonymous on 06/01/2013

    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.

Q
How 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.

Q
Will 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.
