What is 2,4-Dichlorophenoxyacetic Acid?
2,4-D is a member of the phenoxy family of herbicides it is made from chloroacetic acid and 2,4-dichlorophenol, which is produced by chlorination of phenol, is usually called 2,4-D and it is an organic compound with the chemical formula C8H6Cl2O3.
It can also be produced by the chlorination of phenoxyacetic acid.
The manufacturing processes create several contaminants including di-, tri-, and tetrachlorodibenzo-p-dioxin isomers and N-nitrosamines, as well as monochlorophenol.
It is a systemic herbicide that selectively kills most broadleaf weeds by causing uncontrolled growth in them, but leaves most grasses such as cereals, lawn turf, and grassland relatively unaffected.
2,4-D is one of the oldest and most widely available herbicides and defoliants in the world, having been commercially available since the mid-1940 .
In the Vietnam War, it was mixed with other compounds called 2,4,5-trichlorophenoxyacetic acid to make the Agent Orange, a compound that has already been proved to be carcinogenic.
What is 2,4-Dichlorophenoxyacetic Acid used for?
2-4 D has been much used since mid-1940, its primary use is as a selective herbicide which kills many terrestrial and aquatic broad leaf weeds in pastures, orchards, and cereal crops such as corn, oats, rice, and wheat, it is widely used because it’s the cheapest way for farmers to control winter annual weeds by spraying in the fall, often at the lowest recommended rate.
Cereals, in particular, have excellent tolerance to 2,4-D when it is applied before planting.
Over 1,500 herbicide products contain 2,4-D as an active ingredient.
It can also be used in forestry, for stump treatment, trunk injection, and selective control of brush in conifer forests.
In roadways, railways, and power lines, it can be used to control weeds and brush that can interfere with safeness or damage to the equipment.
It has a good effect on aquatic control of weeds that might interfere with boating, fishing, and swimming or clog irrigation and hydroelectric equipment.
The government commonly uses it to control the spread of invasive, noxious, and non-native weed species and prevent them from crowding out native species and also to control many poisonous weeds such as poison ivy and poison oak.
Is 24d harmful to humans? Does 24d cause cancer?
Yes, 2-4D can be considered a toxic compound, it’s a known potential carcinogenic compound in mammals.
Men who work with 2,4-D are at risk for abnormally shaped sperm and other fertility problems it can depend on the amount and duration of exposure and other personal factors.
Some food like oils, fats, and sugars can be contaminated by this herbicide, a series of studies have shown that people who consume this type of food that has been contaminated with 2-4D, have an increased risk for non-Hodgkin’s lymphoma and other malignant tumors.
Some studies have proved that 2-4D increases the formation of cancer-inducing free radicals.
Quercetin is an antioxidant that decreases the effect of free radicals because it blocks the production of mediators involved in the cell’s oxidative damage.
Using quercetine combined with 2-4-D may attenuate the toxic effect of it, but there is still the need to regulate 2,4-Dichlorophenoxyacetic acid and maintain the safe levels.
How do you use 24d?
As said before, 24D is used to kill unwanted weeds such as dandelions, plantain, clover, and chickweed.
It acts by mimicking the action of the plant growth hormone auxin, which results in uncontrolled growth and eventually death in susceptible plants
To apply it you will need:
1) To put on protective gear before spraying it.
To wear safety glasses, socks, chemical-resistant footwear, a long-sleeved shirt, and pants.
2) To Spray the herbicide when wind speed does not exceed 6 to 7 mph.
3) To attach a flat fan nozzle tip to the herbicide spray tank.
Set the pressure to 20 pounds per square inch. Start the tank’s agitator and keep it running throughout the mixing and application process.
4)Fill the tank with 1/2 gallon of clean tap water. Add 2 to 3 tablespoons of 2,4-D herbicide. Fill the tank with another 1/2 gallon of water.
5) Add 1 tablespoon of a surfactant, such as liquid dish soap, to the mixture.
6) Apply the herbicide as a spot treatment by spraying it on individual weeds. Spray the tops and bottoms of leaves, stems, and flowers.
Do not inhale the fumes from the spray, and avoid touching the herbicide with your bare skin.
7)Avoid the treated area until the 2,4-D herbicide has dried completely. Keep animals away from the area as well.
8) Dispose of the remainder of the herbicide at your local hazardous waste center. Clean the tank out thoroughly after using the herbicide. Wash all protective clothing in a separate load of laundry.
