How To Choose The Best Brush Killer Concentrate

Types of Brush Killers

Brush and weed killers are categorized based on different criteria: selectivity, persistence, and systemic vs. contact. Make sure you know which type of weed killer is the best for your situation before rushing to buy a product.

Selectivity

This term means which plants the products will target. If the weed killer is selective, it only kills certain plants and leaves others intact.

Generally, selective killers always deal with woody plants, but sometimes there are broadleaf plants and vines. They will not kill your grass.

Selective weed killers are the best option for most homeowners since you may want to kill individual plants only.

In contrast, a non-selective weed killer will kill any plants that come into contact with it. It is ideal if you are seeking a solution to remove all the vegetation in an area.

Note that non-selective killers are not recommended for lawn or driveway.

Persistence

Persistence refers to the amount of time the brush killing chemicals stay in the soil and prevent plant growth. Some products can last for many months, while others only remove plants and fade in a short time.

If you want to replant in the treated area soon, you should avoid products with long-lasting action.

Systemic vs. Contact

Most of the best weed killers are systemic herbicides, meaning they work from the inside and kill the plants from the leaves down to the roots. This method is probably the best to prevent plant regrowth, but it can take weeks for the plants to die completely.

Meanwhile, contact herbicides only kill the parts that it is exposed to. Normally, the killers cannot reach the roots, thus the plants can regrow quickly. A typical contact weed killer is concentrated vinegar.

Preparation

Weed killers are often available as a liquid concentrate or ready-to-use bottles.

Ready-to-use products contain pre-diluted chemicals, and as the name suggests, you can use them immediately. Usually, they come with a spray wand.

Meanwhile, liquid concentrate is not ready to use straight out of the box. You have to dilute the concentrate with water first, then put it into your sprayer before using it to kill the weeds.

This process can take a while, especially if you are not familiar with mixing brush killing liquid. But with liquid concentrate, you can adjust the liquid’s strength, a huge bonus.

Features To Look For

Strength

The best brush killer should be powerful enough to kill all the weeds and brush. But if it is too strong, it can prevent you from growing any plants in the treated area for a long time. In worse cases, it might harm not only the land but also small animals and children.

You need to make sure the strong chemicals used in the weed killer are safe for general use. The easiest way to do so is to read the product’s active ingredient list and confirm whether the experts approve the chemicals or not.

It is also important to ensure that the weed killers only kill the plants you desire to remove. This attribute is indicated in the product description as well, so take your time to read it carefully.

Safety

Safety is second to strength when it comes to important factors to consider when buying a shrub killer. As mentioned above, you should only choose the products that contain safe and approved chemicals.

Besides, you can check the safety remarks on the label to ensure its safety. Again, reading the label and product description carefully can be more helpful than you thought.

Water Resistance

Your garden will get hosed or watered down at some point, so unless you want the chemicals to be washed away, you had better opt for a product that can resist the water. In other words, the best weed and shrub killer should not be rinsed off so easily.

Fortunately, most weed killers have this feature, although the rainproof period does vary from product to product. Some are only rainproof for 30 minutes, but a few can resist water for many hours.

The thing is, many products need to sit on the plants for a while before they become rainproof, a tough problem in some areas with heavy rainfall. If you are living in such an area, you need a weed killer that turns rainproof quickly.

Brand

If you are new to brush killing, it is best to go for some well-established brands, such as BioAdvanced, Roundup, and Kuzdu. Their reputation proves that their products do work.

In case you are quite familiar with these weed killers, you can check out some cheaper products that guarantee the same results. Read the active ingredient list carefully, and you will be all set.
