What is the mix ratio for 2,4-D?
2, 4-D Mixing Ratio and Application Rate In general, mix 2.5 oz of 2, 4-D weed killer (5 tablespoonfuls) with 1 gallon of water and use it to treat 400 square feet of weed-infested area in your yard. You can double to 5oz per 2 gallons of water for treating 800 to 1000 square feet of weed-laden grass.
How do you mix 2,4-D for a hand sprayer?
How to Mix 2,4-D for a Hand Sprayer or Backpack. If you are mixing 2,4-D by Hi-Yield in your handheld or backpack sprayer, add 5 ounces of 2,4-D per gallon of water. This will be strong enough to kill broadleaf weeds but not so strong that it can cause damage to your lawn.
Does 2,4-D Amine need a surfactant?

Why is 2,4-D banned?
Dow stated the product would be available in 15 US states and Canada for the 2016 crop season. On 21 August 2013, the Australian Pesticides and Veterinary Medicines Authority (APVMA) banned selected 2,4-D high volatile ester (HVE) products due to their environmental hazards.
Can I mix Roundup and 2,4-D?
Mixing the glyphosate with another herbicide with another mode of action can also be very helpful. One example is to add 2,4-D to glyphosate applications according to label directions. Glyphosate binds to soil particles, so if muddy pond water is used, the herbicide effectiveness will be reduced.
Does rain wash away 2,4-D?
Rain negatively affects 2,4-D if the weed killer isn’t allowed to properly dry first. Rainfall within 24 hours after 2,4-D application can dilute your herbicide, limiting its effectiveness. For this reason, it’s important to make sure there is no forecasted rain for at least 24 hours when applying 2,4-D.
Should I mow before spraying 2,4-D?
Applying Postemergent Killer When applying a postemergent herbicide, do not mow the lawn before application and wait at least three days after it has been applied before cutting your lawn. The herbicide needs as much leaf blade as possible to ensure the plant absorbs the chemical.
Is 2,4-D the same as Agent Orange?
2,4-D is not Agent Orange. Agent Orange was a mixture of two different herbicides: 2,4,5-T and 2,4-D (as well as kerosene and diesel fuel). 2,4,5-T contained high levels of dioxin, a contaminant, found to cause cancer and other health problems in people.
Will 2,4-D harm animals?
Some of the ester forms of 2,4-D can be very toxic to fish and other aquatic life. The salt forms may be only slightly toxic to aquatic animals. Aquatic animals are more sensitive to 2,4-D as water temperature rises. 2,4-D may be moderately toxic to practically non-toxic to birds if they eat it.
