The Best Permanent Killers of Grass and Weeds

A common issue for the average individual who owns a property is trying to control the rampant spread of weeds and errant grass. Throughout history, humans have owned livestock to help keep these growths to a minimum. In the modern age, people need to rely on their own hard work and ingenuity instead.

To be as effective as possible, you should invest in a permanent killer of grass and weeds to keep the manual labor to a minimum. While it is possible to remove grass, clover, dandelions, and crabgrass by hand, a more ideal solution is using a spray herbicide that can be applied directly to the problem and then require no more work for the rest of year.

Because there are many herbicides on the market, it’s important to know what you’re getting yourself into when buying one. After all, using the wrong ingredients can leave a plot of land barren for months and even years. Here, the best permanent killers of grass and weeds from 2019 are examined to help you find the right option for you.

What to Know When Picking an Herbicide

An herbicide is a substance that is designed to be toxic to plants and is meant to be used as part of pest management. Plants qualify as pests when they start to choke out desired fruits, vegetables, flowers, and even grass. 

Herbicides have been around for a long time and have undergone numerous changes over the years. While people no longer use mercury as a pesticide, there are still many toxic ingredients in the most effective herbicides that are important to know. Here is some of the info you need when trying to find the best permanent killers of grass and weeds. 

The Best Permanent Killers of Weeds and Grass

Organic vs. Chemical

Every ingredient in an herbicide counts as a chemical, but people draw a difference between models that try to use environmentally friendly, organic ingredients and those that focus on chemicals. While organic herbicides are simple and tend to be safe around pets and children, they are not effective killers. For this reason, many of the products on this list fall into the traditional “chemical” category. However, there are some organic alternatives, but they require multiple sprays to become truly permanent killers.

When you choose to go the organic route, it’s important to look for acetic acid, which is basically vinegar under its more official name. Just as this ingredient can kill the taste buds, it can also eliminate unwanted plants by targeting both exterior and interior cells.

Common Ingredients

Some of the most frequently seen ingredients in effective herbicides are acetic acid, glyphosate, pelargonic acid, and sethoxydim. These components share similar characteristics, including being acidic and producing a ‘burn’ effect that kills weeds and grass by targeting the visible portion and then seeping into the soil to kill the roots. Since these are the most effective ingredients, it’s important to search for a product that includes at least of these when choosing the best permanent killers of grass and weeds

Easy to Use

When shopping for the best permanent killer, you need an option that you can actually use effectively. Most of the powerful herbicides come in a liquid format that requires a separate container to be used. So, you might need to invest in a spray bottle or a more reliable backpack sprayer that you can carry around.

However, liquid herbicides are simpler and easier to use than granules, which tend to clump and require the user to get closer to their target. For this reason, the pesticides on this list are liquids that can be transferred to other containers and sprayed. While granules can be effective, they are difficult to target specific plants and might disintegrate and hit the roots of desired growths.

This is a powerful herbicide that attacks unwanted vegetation deep in the roots to stop it from returning even as the visible part of the plant dies. Unlike some other herbicides, this one comes in a bottle with an optional spray top, so it doesn’t need to be transferred to another container to be used.

RM43 43-Percent Glyphosate Plus Weed Preventer

This herbicide comes in containers that hold 32 fluid ounces, or roughly 1 quart of liquid. The primary ingredient is glyphosate, one of the most efficient killers of unwanted weeds and grass for commercial and residential properties. While it needs to be transferred to another container, it can be used to treat just about every spot around the yard, including driveways, walkways, gardens, and fence lines. Because of its strength, the RM43 should not be used around the root areas of trees and desired vegetation.

Once RM43 has been applied to the ground, no unwanted vegetation will grow for up to 12 months, meaning areas only need to be treated once. This is an excellent option for someone who is tired of treating their yards every few months to eliminate unwanted grass and weeds. A single container treats around 4,300 sq. ft. and can be used on woody plants or vines that grow along the sides of buildings.

  • Treats a large area effectively
  • Stops unwanted vegetation growth for 1 year

Remedy Ultra Specialty Herbicide Weed Killer & Brush Control

The Remedy Ultra Specialty Herbicide is an extremely strong model designed to kill wild plants that grow around designated areas like backyards, pastures, and driveways. The main ingredient is triclopyr, a powerful and acidic herbicide that starts to kill unwanted grass and weeds on contact. Because of its power, targeted grass and weeds will not return after thorough spraying.

Keep away this herbicide from children, pets, and other animals because it contains highly toxic chemicals. However, it is extremely effective. You need to pour the mixture into a separate sprayer since one is not included in the original bottle. Despite its strength, this is an economical option that actually has a low environmental impact since it dissipates quickly once in the soil. Unlike other options, it can control brush and plants with woody stems. Each container holds 1 gallon of solution.


  • Powerful and acidic
