What is a Weed Killer?

In Photo:Ortho Nutsedge Killer For Lawns

The weed killer, also referred to as a herbicide, is a chemical substance that is used to destruct unwanted plants or inhibit their development.It can be divided into two broad classifications: organic and inorganic.

A few common examples of organic herbicides are amides, dinitrophenols, carbamates, bipyridyl compounds, and chlorophenoxy compounds.Some of the most popular inorganic weed killers likewise include sodium arsenite, sodium chlorate, and copper sulfate.

Meanwhile, there are a couple of terminologies that are frequently used in relation to how herbicides are being applied. They include:

Intended Outcome

This refers to how you want the herbicide to exterminate unwanted plants. You can either control by completely destructing nuisance weeds or merely suppress by incompletely controlling the growth of grasses.


Selective weed killers are formulated to either suppress or control targeted plants without in any way affecting the development of other ornaments around them.As the name suggests, non-selective weed killers do not care about which plant species they come into contact with. These make them ideal on railways, waste grounds, and other industrial areas where a clear area is preferred.

Method of Application

Foliar-applied herbicides are those applied on the plant itself, so they can be absorbed by the plant’s exposed tissues. Common examples of foliar-applied weed killers are 2,4-D, glyphosate, and Dicamba.On the other hand, soil-applied herbicides go deeply into the roots of unwanted plants. They are also utilized as pre-emergence and pre-plant treatments. Examples of soil-applied weed killers are trifluralin and EPTC.

Timing of Application

  • Pre-plant herbicides are applied to the soil before planting. They are mostly non-selective weed killers.
  • Pre-emergence herbicides are used before weed seedlings get the chance to develop or emerge through the surface of the soil.
  • Post-emergence herbicides are likewise utilized right after weed seedlings have emerged through the surface of the soil. Unlike pre-plant and pre-emergence herbicides, post-emergence weed killers can either be root-absorbed or foliar or can be either selective or non-selective.

Although chemical weed killers are popular choices among homeowners or landscapers, their adverse effects into people, animals, and the environment are abhorrent to some. As a result, conservationists have come up with ways or formula to create natural weed killers using common household substances such as vinegar, lemon juice, gin, alcohol, and dishwashing soap.

Up until today, the signature herbicide of Monsanto called “glyphosate” is considered the most-widely used weed killer in the history of chemical agriculture.

Different Types of Weed Killer

There are five common types of weed killer:

Systemic weed killer

A systemic weed killer is formulated such that it gets into the transport system of the plant. It works a bit slow, but it effectively destructs a targeted plants by restricting the latter’s capability to transport nutrients and water until it dies.

Contact weed killer

A contact weed killer eradicates all the plants it comes into contact with. The herbicide first enters the leaf through its stomata which is open most especially when the plant is growing. Therefore, it’s most effective when used during the growing season of the targeted plant.

Another advantage of using contact weed killers is that they don’t cause any damage or unwanted effects on your lawn or garden soil. Almost always, it needs more than a week for contact weed killers to take effect into targeted plants.

Residual weed killers

Residual weed killers are best used on patios, driveways, or any other hard-standing areas. If used in the soil, they could sit in there for several months. Therefore, the growth of any other forms of plants may be prevented and the soil may be rendered inactive for quite some time.

If you plan to grow some plants or vegetables on your garden right after eliminating all the weeds and grasses, avoid using residual herbicides.

Selective weed killer

A selective weed killer is specially-formulated to kill only a specific plant. For example, a selective herbicide for lawn weeds such as daisy, buttercup, and dandelion would have no impact on narrow-leaved plants such as grasses.

Some of the most popular selective weed killer brands are Dicamba and Oust by Du Pont. Both of which can be used to destroy grasses in the forest while preserving young tree saplings.

Our Recommendation:Southern Ag 2,4-D Amine Weed Killer

Non-selective weed killer

The non-selective weed killer is the type that needs extra care and caution when used. This is because it can kill anything that it comes into contact with. As a safety precaution, you should cover all ornaments and plants nearby so they don’t get damaged. Also, never spray a non-selective weed killer amidst windy conditions.
