Best Herbicide Reviews | 5 Options to Help you Decide

Choosing the best herbicide for your needs

Herbicides have several uses, from farming and agriculture to gardening and maintaining a well-manicured lawn. In order to find the best herbicide, you first need to determine your needs in your yard or lawn and what you are trying to accomplish by using an herbicide.

Most herbicides can be classified into two major types: selective and non-selective. They both work as post-emergent herbicides, meaning they target weeds and other vegetation. After it has emerged from the soil. Usually, the herbicide is sprayed onto the foliage of the plants where it travels down and kills the root.

Selective or non-selective herbicides?

Let's begin with selective herbicides, these are formulated to only kill certain types of plants such as broadleaf plants, which include many of the most common type of weeds including dandelions, clovers, and crabgrass. Also, selective herbicides are safe to use on lawns and on other types of vegetation since they only target specific plants. They are also a great herbicide to kill weeds while leaving grass and other plants intact.

Non-selective herbicides work by killing all types of vegetation and are typically the best total vegetation killer. They are not the best for weed control throughout your lawn as it is an herbicide that kills everything including they grass, brush, weeds, plants and shrubs.

Non-selective herbicides typically have several uses in agriculture in addition to its use in residential yards. Most non-selective herbicides vary in the amount of time they control weeds and other vegetation, but it typically ranges between months and sometimes up to a year depending on the herbicide. But, you have a few options we will discuss if you are looking for the best way to get rid of weeds permanently.

Use vinegar as an organic herbicide

If you want a more natural way to get rid of weeds, vinegar is a great option since in contains acetic acid. Acetic acid, commonly found in vinegar is a great way to get rid of weeds as it acts as a natural herbicide. Vinegar can be boiled down to yield a stronger percentage of acetic acid.

It is then sprayed onto the leaves and foliage of the weeds where it travels down to the root and kills the weed. It is also very convenient as most people have vinegar in their homes as a normal household product.

What kills weeds permanently?

If you are looking for the best way to kill weeds permanently, you will want to choose a three-way herbicide that typically has glyphosate as an active ingredient. Most glyphosate-based herbicides contain three components – the active ingredient, water, and a non-ionic surfactant blend.

In agriculture, surfactants, short for “surface-acting agents”, help make herbicides work more efficiently. They reduce the surface tension of water, and since herbicide sprays are mostly water, this keeps the spray on the foliage and leaves of the weed allowing the glyphosate to work more efficiently.

Most herbicides that have glyphosate as its active ingredient also kill other types of vegetation as it is non-selective, so you should be careful about exposing other types of vegetation to it.

What kills grass and weeds permanently?

If you are looking for an herbicide that will kill all vegetation and essentially act as a ground sterilizer, using an herbicide with pramitol as its active ingredient will kill all vegetation it comes into contact with. Pramitol is a salt and acts as a permanent vegetation killer and will preventing plant growth for up to 1 year after treatment making it the best ground sterilizer.

It is a great choice for rock beds, driveways, construction sites, pipe yards and other commercial areas, and it has several uses in farming and agriculture. It is also non-selective, meaning it will kill all types of vegetation and is considered pre-emergence, meaning it prevents growth from occurring.  Nothing will grow where it is applied for up to 1 year, so this is a great option if you are trying to figure out how get rid of weeds permanently.

Overall, there are several types of herbicides whose functions vary based on the active ingredient and type of herbicide. The best herbicide will likely depend on your need.

If you are simply looking to control your clovers or dandelions in your yard, a selective herbicide might be your best choice. But if you are looking to kill all of the vegetation in a certain area, a total vegetation killer might be your best option.  You should always choose an herbicide that can meet your requirements and fulfill your needs.
