2,4-D Amine is one of the oldest herbicides being used by gardeners and botanists for killing broad-leafed weeds. A lot of people also use this herbicide for killing trees. But is it really effective and what is the correct method for using it? Let’s take a look.
2,4-D Amine can be used for killing small to medium-sized trees. It is primarily used for weeds control but can be effective on smaller trees as well. For larger trees, the best way to use it is through cutting the tree down to a stump and treating the stump with the chemical.
What Is 2, 4-D Amine?
2,4-D or 2,4-Dichlorophenoxyacetic acid is an organic chemical that has been used as an herbicide since the early 1940s. One of the advantages of using 2,4-D amine is that while it kills most broadleaf weeds, it has very little effect on most grasses. This makes it the ideal choice to be used in backyards and lawns.
One of the other reasons for its popularity is that most crops are resistant to this chemical. A lot of farmers find using 2,4-D cheap as well as ideal as it can kill a lot of weeds but not affect their crops.
How Does 2,4-D Amine Work?
2,4-D is a systemic herbicide which means that it is absorbed by the foliage and the leaves of the trees and transported throughout the tree till its roots. It works by mimicking a growth hormone within the plant known as auxin.
This leads to uncontrolled growth within the plant which cannot be sustained for long periods of time. This eventually results in curling of the leaves and stems of the plant which also leads to its death.
What Is the Most Common Use For 2,4-D Amine?
2,4-D is primarily used for controlling the growth of broad-leafed terrestrial and aquatic weeds. It is an ideal choice by botanists and homeowners for controlling the growth of unwanted species in their lawns as the chemical is not as effective on most grasses.
It is also heavily used by farmers for controlling the growth of unwanted species within their crops. In forestry, 2,4-D is mainly used for stump treatments.
Will 2, 4-D Kill Trees?
Although 2,4-D is majorly used for weed control, it can also be used for killing trees. It is recommended to use this herbicide for the killing of small to medium-sized trees, as it is not as effective in killing larger trees.
You can use 2,4-D to kill larger trees when they have been cut down to their stumps. Once directly poured on freshly cut stumps, 2,4-D will effectively stop any future growth of the tree.
How to Kill Trees Using 2,4-D?
For directly killing small to medium-sized trees with 2,4-D, you can use a variety of methods depending on the size of the tree and the conditions you are dealing with. Let’s take a look.
Before we start with any methods, make sure you take all the safety precautions necessary. 2,4-D can be very hazardous to your health, especially if you have kids or pets around. Make sure you are wearing protective gloves, eyewear, full-sleeved clothes, and boots.
Basal Spray Technique
Whether you are treating a freshly cut stump or a small tree, the basal spray technique is an excellent method for killing trees.
You will need a portable sprayer, 2,4-D, diesel fuel, and Silvex or Kuron (this is optional but adding this can increase the potency of the herbicide).
Keep in mind that this method only works if the diameter of the trunk of the tree is less than 7 inches.
Mix 1 pint of 2,4-D with 3 gallons of diesel fuel to make the mixture. You can also add half a pint of Silvex to increase its efficiency, but this is optional.
Spray the bottom 1 foot of the trunk with the solution and let it get absorbed by the tree.
The general rule of thumb is to use 3 fl. Oz. per inch of trunk diameter.
Cut Surface Treatment
Cut Surface Treatment is also highly effective and extremely easy to perform.
You will need an ax or a chainsaw along with a portable sprayer and 2,4-D.
Using an ax, make deep gashes into the trunk of the tree around its entire circumference.
If you are dealing with a stump, make gashes on the top portion as well.
Spray undiluted 2,4-D on these gashes until you can see the herbicide dripping from them. let the tree completely absorb this.
Make sure there is no wind, water, ice, or frost on the trees while performing any of these methods. Not only will they reduce its efficiency, but the wind can also carry the herbicide long distances.
What Is the Best Method for Using 2,4-D Amine to Kill Trees?
The most efficient method for using 2,4-D is by directly applying it to a freshly cut stump of the tree. Although directly using it on trees can kill them, using the herbicide on the stump will give you the fastest results.
2,4-D Amine can be used to kill small to medium-sized trees, it can also be used on tree stumps to stop any further growth. You can use Basal Bark Treatment or Chemical Injection Method with the chemical for best results.
