Brush Killer Buyer’s Guide
These days, there is an abundance of different brush killers on the market, so it can be quite challenging to select one for your property. Before you purchase a specific product, there are a number of characteristics you should consider.
Types of brush killers
The size of your property and how much weed you want to eliminate determine the type of brush killer you should purchase. Modern brush killers can be divided into two main categories.
 1. Concentrated formula
The majority of products that you can purchase nowadays are concentrated and come in the form of liquids. Before you can use such products on your property and pour them into a sprayer, you have to mix them with water in a proportion stated on the packaging. While this means more effort on your part, the advantage is that such brush killers usually last more. If you have a large property, purchasing such a product would be the wisest decision.
 2. Ready-to-use products
In addition to the concentrated brush killers, there are also ready-to-use solutions that don’t require any mixing. Such products usually come already with sprayers, so the process of using them is as straightforward as it gets. If you have a lot of weeds, it is best to transfer the product into a larger sprayer because it will take you a long time to cover all weeds with the original sprayer.
Ingredients
The next thing that you should pay attention to before buying a brush killer is its ingredients. The formulas of modern brush killers are often quite similar, as there are four main ingredients that you can see most often. The main difference is in the combination of such components and their concentration. All of them are effective against weeds, but there are still a few differences when it comes to what kinds of plants they eliminate best.
Triclopyr
This is the most widely used component that you will find in modern brush killers. This component belongs to selective herbicides, which means that it cannot kill all plants that it covers. It is particularly effective on sweetgum, mesquite, and a large number of other woody plants. The product containing triclopyr is mostly suitable for controlling the lawn and areas close to it, as it won’t affect most types of lawn grass.
Glyphosate
The next ingredient you are likely to see when looking for a brush killer is glyphosate. As opposed to triclopyr, this component is considered a non-selective herbicide. It means that it eliminates all types of plants that it touches, including grass, vines, and woody plants. One thing to note is that you have to be careful to avoid spraying plants that you want to leave.
2,4-D
This is another widely used selective herbicide that is highly effective at killing broadleaf weeds. It is often used in combination with triclopyr to get the best results.
Fluazifop
Also often used with triclopyr, fluazifop is an ingredient that works well on broadleaf weeds, thick grass, and sedges. It is especially effective when used along with another herbicide.
What to Consider When Buying a Brush Killer
In addition to looking at the ingredients, there are other characteristics you should consider.
When will the first results appear?
Brush killers differ when it comes to how long you need to wait before you start seeing the results. In the case of vines and grass, you are likely to notice them withering away in just several days. Woody plants will definitely take longer, and you might not notice any difference in how they look for up to 4-6 weeks. You can see the information on how often you need to reapply a brush killer in its instructions.
Rainproof
Another important thing to look for when choosing a brush killer is whether it is water-resistant or not. A large percentage of modern brush killers are rainproof, which means that you can use them even if there is a chance that it will be raining tomorrow. At the same time, brush killers don’t become rainproof instantly, and the waiting time depends on the manufacturer and ingredients. In some cases, it can take 24 hours while other products become water-resistant in just 30 minutes. Depending on the climate where you live, you should choose appropriate products, and it is still better to apply brush killers on days when it doesn’t rain.
Safety
The majority of brush killers that you can freely purchase are safe for commercial and private use if you follow all the safety precautions. If you purchase a product that needs to be mixed, you should follow safety measures on the packaging. You shouldn’t neglect recommendations and wear protective gloves or clothing if necessary. If you have pets or children, you should look for products that will not be harmful to them.
Brush Killer FAQ
Below, I would like to answer some of the most common questions that I’m getting regarding brush killers.
What kills brush permanently?
Brush killers that contain triclopyr, glyphosate, 2,4-D, or fluazifop are created to kill vegetation permanently. The way they work is that the product enters leaves or stumps of plants and then moves through the stems right to the roots where they can be destroyed. The more concentrated brush killers are, the faster you will see the results. The plants that have been affected by brush killers won’t grow back again, but there is always a possibility that new seeds will get into the ground, and you will see new weeds later.
What is the strongest brush killer?
A lot of brush killers contain triclopyr as the main active ingredient. Products that have a high concentration of this ingredient are considered the strongest ones, so if you have hard-to-kill weeds or a large property with constantly growing weeds, you should choose the strongest option. Fertilome is one of the most potent brush killers on the market because it has an 8.8% concentration of triclopyr as opposed to many products that contain only 1% or even less.
Also, if you want a powerful solution, there are brush killers that use a combination of triclopyr with other ingredients that also help achieve the desired effect. One thing to note is that even concentrated brush killers often require several applications when you need to eliminate trees or other plants that can be difficult to cope with.
What kills brush and small trees?
The effect of brush killers varies depending on the ingredients. Regardless of the components, most brush killers get rid of tender vines and plants, but not all of them will be effective on small trees and woody plants. To get rid of small trees, you should use products with triclopyr or glyphosate, which are considered powerful enough to deal with such vegetation. By applying the product to the leaves of plants, the poison will reach the roots. In many cases, it is necessary to apply a brush killer more than once after several weeks to kill a tree.
Is brush killer stronger than Roundup?
Roundup is considered a non-selective herbicide, which means that it eliminates all plants that it touches. As opposed to Roundup, a brush killer belongs to the group of selective herbicides that eliminate weeds, trees, and shrubs with broader leaves. A brush killer is designed in such a way that it doesn’t affect grass and doesn’t kill plants that have narrow leaves. If we consider the selection of plants that can be eliminated with brush killer, it is definitely stronger compared to Roundup.
Choose the Most Suitable Solution for Your Property
These days, the variety of brush killers is impressive. Before choosing a brush killer, you should consider the size of your property, how safe it is, and what ingredients it contains. The brush killer from Fertilome is a top pick of this guide due to the combination of its effectiveness, reasonable cost, and quick results. It effectively eliminates plants that are difficult to get rid of, so it is a popular choice for small and large properties.
