2, 4-D Weed Killer Is A Lethal Solution for Broadleaf Weeds


While to the average joe, “2, 4-D" appears to be weird combination of letters and numbers, to lawn care experts and agricultural workers responsible for managing lawns and turf, 2, 4-D is regarded as one of the most helpful chemicals in killing problematic broadleaf weeds.


What may surprise you is that  2, 4-D is perhaps the most utilized broadleaf weed killer around the world. In the United States, 2,4D is in the top three for most used herbicides for residential and commercial landscapes. 2, 4-D comes in a variety of different formulations--from liquids, to dusts and granules.


Solutions Pest & Lawn is proud to carry 2, 4-D Amine Selective Weed Killer, which is one of our best selling herbicides, and for good reason, it works!



Background Information on 2, 4-D

There is an interesting story of how 2, 4-D came to be. The chemical mixture was believed to be developed by scientist Dr. Franklin D. Jones who initially wasn’t trying to come up with the weed killer for financial reasons or acclaim, but rather was trying to combat the effects of poison ivy that was growing in his yard which harmed his children who came into contact with the plant and suffered allergic reactions.


His experimentation led him to the naturally occurring plant growth hormone, indoleacetic acid (IAA).However, Dr. Jones found that the chemical was far too unstable. A synthetic alternative was need, something that was stable that he could experiment with. The synthetic version he developed was 2, 4-D.


What Dr. Jones developed was more than just the world’s first selective herbicide. What he created was a fantastic solution to human problems such as food scarcity, infrastructure management and invasive and potentially poisonous weeds.


The development of 2, 4-D is regarded as one of the top 75 innovations in the last 75 years by the Henry Ford Organization. 2, 4-D continues its tackling of weed problems as one of the most widely-used herbicides around the world.


Over the years since it’s development in the early 1940’s, 2, 4-D has evolved scientifically to meet regulations set by the US EPA, the European Commission and other regulators. In the last 60 years, there have been over 40,000 different research studies done on 2, 4-D, going down as one of the most researched chemicals in history. This large amount of research was not just for its role in pioneering in the field of selective herbicides but to also make sure it meets the world’s modern human health standard.


Scientists have set 2, 4-D as the benchmark in the study of herbicides as most new herbicides being developed, 2, 4-D is looked at as part of procedure to make sure that the development is meeting the standards that 2, 4-D has set.

2, 4-D: The First “Selective” Herbicide

2, 4-D is regarded as the world’s first selective herbicides because of the fact that when applied to plants, it suppressed "dicots" (plants with two seed leaves, also known as broadleaf plants) while leaving "monocots" unaffected (plants with one seed leaf or thin leaves).

This basically means that it isn’t a herbicide that kills all plants that it touches and can be safely sprayed on grasses and plants like wheat, corn, rice and other crops without harming them. It only harms broadleaf weeds.


Why 2, 4-D Weed Killer is so Effective

How 2, 4-D works as a weed killer of broadleaf weeds is interesting. It basically works like a lethal disease to the broadleaf plant it is sprayed upon, as it causes the plant to grow uncontrollably to the point that it dies. The way this occurs is the chemical creates a sort of unregulated growth that leads to the destruction of the broadleaf weeds vital tissues that it needs to survive. In short, it overgrows itself to death.

2, 4-D weed killer selectivity makes it so it only affects broadleaf weeds and not grasses because these two different classifications of plants work differently when it comes to chemicals which move through it’s leaves. While broadleaf weeds have their growing point at the tips of the leaves, grasses grow from the base. Thus, the 2, 4-D herbicide is able to kill broadleaf weeds while sparing desired grasses.


Another  reason that 2, 4-D  is such a popular product is because it is very affordably priced. There are over 1,500 herbicide products that contain 2. 4-D, and it's often mixed with other active ingredients like dicamba.


Toxicity Concerns of 2, 4-D

As noted earlier, 2, 4-D has been studied and widely researched by scientists and concerns have been raised about the toxicity of 2, 4-D and how it can affect the health of the environment as well has humans. Some have stated that using 2, 4-D carry the risk of spreading carcinogens which can “possibly” cause cancer.


However, there have been conflicting reports and in fact, 2, 4-D amine has a relatively low toxicity compared to other pesticides.


Solutions Pest & Lawn experts can assure you that 2, 4-D Amine is safe to use and as long as you wear the proper safety gear and equipment when handling this product, you will have nothing to worry about when applying it to your lawns.

Jesse M on Mar 29, 2018
BEST ANSWER: For the 2 4-D amine it is best to keep any drift away from desired trees. Do not allow spray to drift onto or contact foliage, fruit, stems, trunks of trees or exposed roots as injury may result. This product is also used to kill trees by injection or foliar contact.
will 24-d harm frogs
pug on Apr 29, 2017
BEST ANSWER: No the 2, 4 D Amine will not harm frogs.For Aquatic Uses: Fish breathe dissolved oxygen in the water and decaying weeds also
use oxygen. When treating continuous, dense weed masses, it may be appropriate to treat
only part of the infestation at a time. For example, apply the product in lanes separated
by untreated strips that can be treated after vegetation in treated lanes has disintegrated.
During the growing season, weeds decompose in a 2 to 3 week period following treatment.
Begin treatment along the shore and proceed outwards in bands to allow fish to move into
untreated areas. Waters having limited and less dense weed infestations may not require
partial treatments.
Do the weeds come back?
A shopper on Apr 22, 2018
BEST ANSWER: In my experience no, at least not the ones I sprayed. Others have come up in other areas but that's why putting down a pre-emergent is important. Dandelions however will not go down with a pre-emergent, but these you can just spray or pull out.
What is the easiest way to apply 2 4 D amine to your entire yard? Can this be done with a sprayer that attaches to your garden hose.

How much amine 2 4d to put in 80 gal. Of water?
A shopper on Jun 30, 2018
BEST ANSWER: It depends on what you intend to spray it on. I have an invasive broadleaf plant called fig buttercup that was spreading all over my backyard, getting worse every year. Back in early April, when they come out, I was advised that you use 4oz of product per 1000 Sq ft of area. I was also told to mix it with either 1 or 2 gallons of water but not to exceed the 1000 Sq ft of area. It worked pretty well as I saw a bunch of of it die within a couple of days. I'll know more next spring since the buttercup goes dormant in late May. Since you are mixing so much it could be for a different purpose.

It works.
My problem was ground ivy which was well established in my front and back yards. I sprayed 2,4-D Amine with a hose-end sprayer using 12 ounces of product for 9 gallons of water to cover the entire 4000 square feet. Two weeks later I sprayed again with the same mix. Now, another two weeks later, I can only find a very few remaining weeds of any kind.
