Anecdotally, diesel fuel is effective at killing weeds. The high-powered jet of fuel can penetrate the weed's leaves and stem, causing the plant to quickly die.
However, there is little scientific evidence to support this claim. Diesel fuel is a complex mixture of hydrocarbons, and it is unclear which component or components are responsible for the weed-killing effect. In addition, diesel fuel is not selective, so it will kill any plant it comes into contact with, including desirable plants.
Diesel fuel can also be harmful to the environment. When it is sprayed on weeds, some of the fuel will inevitably evaporate and enter the atmosphere, contributing to air pollution. In addition, runoff from sprayed areas can contaminate groundwater.
For these reasons, many experts recommend against the use of diesel fuel for weed control. There are safer and more environmentally friendly options available, such as herbicides that are specifically designed to target weeds.
A fresh viewpoint: Weed Killer Kill Trees
How does diesel fuel kill weeds?
Diesel fuel is an effective weedkiller because it contains high levels of aromatic hydrocarbons. These chemicals are damaging to plant life and cause weed leaves to dry out and die. Diesel is also a volatile substance, meaning it evaporates quickly. This makes it ideal for spot-treating weeds in areas where you don't want to harm desirable plants.
What are the best conditions for using diesel fuel to kill weeds?
Diesel is an effective means of killing weeds, but only under the right conditions. If the temperature is too cold, the diesel will not be effective. The ideal temperature for using diesel to kill weeds is between 80 and 90 degrees Fahrenheit. The diesel must also come into contact with the weed leaves in order for it to be effective. This means that the weed must be sprayed directly, or the diesel must be poured onto the leaves.
Diesel is harmful to the environment and should only be used as a last resort. If possible, try using other methods of weed control first, such as pulling the weeds by hand, using a hoe, or applying a herbicide.

Frequently Asked Questions
What happens if you put Diesel on grass?
Diesel will kill crops and flowers, so beware. One downside of diesel is that it probably won’t kill the weeds permanently.
Does Roundup kill weeds like diesel fuel?
This is a difficult question to answer definitively, as diesel's efficiency in terms of weed killing tends to be greater than that of Roundup. While it's possible that either product could kill all weeds with proper application, it is likely that diesel is more efficient in this regard.
How long does it take for diesel to kill grass?
Yes, diesel will kill grass in 48 hours.
How to kill weeds using diesel fuel?
One way to kill weeds using diesel fuel is to pour it into a jug and use the funnel to disperse it into a spray bottle.
What happens when you spray diesel on weeds?
Diesel fuel is a volatile and strong-smelling liquid that can easily irritate your respiratory system if it's inhaled. Spraying diesel on weeds will kill them quickly, but the chemical smell can remain for a while so be careful if you're around people or animals.
