Will Gasoline Eradicate Weeds?

Gasoline is primarily used as fuel to power the engine of farm machines. It comes in handy in making you traverse long distances and also get work done more efficiently.

Put simply, your gardening is made easy with gasoline. But to what extent exactly should you use gasoline concerning gardening?

For example, we are privy that some gardeners use gasoline to control weeds in their lawns, crop fields, and ornamental beds.

Given the loss weeds bring about in the garden, you may have noticed gasoline is pretty effective after other methods have failed to eradicate the notorious weeds.

Well, the truth is gasoline (petrol) takes out weeds effectively. And sure enough, though unorthodox, you can use the fuel to eliminate weeds in your garden or lawn.

However, you want to deploy gasoline vis-a-vis your safety concerns. You also want to look at the environmental laws affecting your state to ensure you are not breaching any.

That being said, spot treating your weeds is the best way to go about this if you’re fixed on using gasoline. That means spraying only a tiny amount of gas on the foliage of the weeds.

Some precautions you should consider are:

  • Spraying the gasoline during cooler days.
  • Avoiding watering your garden after the gasoline spray.
  • Spraying the weed foliage and not the soil. Set the nozzle to jet spray.
  • Keep children and pets away during spray.
  • Bend down during spraying to have better control of what weeds to spray.

Factors To Consider When Using Gasoline For Weed Control

Some factors to consider before you opt for using gasoline for weed control are:

Environmental Safety

First of all, you should know that gasoline is highly toxic to all living beings. It can cause severe damage to the skin, eyes, and lungs if ingested or inhaled.

During the spraying application, the toxic substance comes into contact with the topsoil in your garden. Consequently, the gasoline will sink deep down into water underground or the storm sewer.

Imagine having well water around. Your drinking water gets contaminated on the go putting your health at risk. The worst part is that human eyes can’t see the low-level toxic elements of gasoline in drinking water.

Using gasoline to get rid of weeds boils down to contaminating the water sources in your garden.

Although it is true that gasoline is highly volatile and will evaporate completely from an impervious surface, on the contrary, the soil is porous, and the gasoline traces will find their way down the soil.


Gasoline is highly flammable, and you should handle it with caution. Any contact or proximity to a fire or power source could ignite the fuel.

The last thing you want is to set your garden on fire. Some flammable contact points to avoid are electrical sparks, hot engines, and pilot lights.

You need to also keep your health in check by using safety gear like gloves and masks to help you avoid inhaling the toxic vapor from gasoline fumes.

Storing gasoline as a herbicide in your home for extended periods may also pose a challenge. It’s best to store it in a cool, dry place away from home. It should also be kept away from the presence of children and pets.

Gasoline Flash Point

If intending to use gasoline against weeds growing in your garden, you must understand its flashpoint. The gasoline flashpoint is at -43°C.

A flashpoint is a point at which a substance has generated sufficient vapor to support a flame.

What this means is that gasoline is highly flammable even at ambient temperatures. Gardeners cannot control weeds in their gardens at ambient temperatures as the fuel will readily catch fire.

Type of Material in Use

Gasoline quickly corrodes plastic materials, gumming them up, which makes them less functional.

For a better experience, use a steel can containing a tubular spout.



Gasoline has the primary function of fuel, powering farm machines and vehicles. However, gardeners are beginning to find other uses of gasoline, one of which is eliminating weeds.

However, the consequences of using it far outweigh the benefits.

Not only do you risk polluting your environment, but your health and safety are also at stake. We recommend using less harmful and scientifically proven methods of eradicating weeds to keep your garden clean.
