Does Diesel Kill Weed? (Yes, It Sadly Does)

Some planters, fed up with these persistent and pesky weeds, opt for diesel fuel to kill the weeds. Diesel is a type of petroleum that contains toxic substances harmful to the environment.

But, does diesel kill weed for real?

Well, frankly speaking diesel will surely kill the weeds in your garden, but that is temporary. It will kill not only the weeds but also all other plants that it meets. Thus, it is best to go for any other non-toxic alternative to get rid of weeds in a good way.

Does diesel kill weed?

To answer the question directly, yes, diesel kills weeds in your garden. Diesel is a sort of fuel with a chemical property that is not really eco-friendly. While diesel will kill the weeds in your garden, it will also not leave the other plants that come in contact with it.

It contains almost 75% aliphatic hydrocarbons and 25% aromatic hydrocarbons. Together, these chemicals kill every plant it comes in contact with, while until the chemical is removed, the seeds will not germinate.

Diesel also does not mix with the soil very easily. The sticky fluid takes almost 4 years to dilute completely in the soil. It will also kill the small insects like pests or good organisms in your garden.

Therefore, using diesel is not a very good hack. It can hinder the growth of your plants and affect their entire root system. 

Diesel, if used as a mode to kill weeds, should be used in a specific manner. The diesel should be spread on the weeds when there is no chance of rain for at least 48 hours.

This will not let the diesel contaminate other garden areas along with the rainwater. The diesel fuel should be sprayed on the weed plants with a spray bottle to prevent it from damaging the entire garden.

The diesel should be sprayed close to the roots, so the weeds are killed permanently. After the process, wait for at least three weeks before you plant a new plant there, as diesel takes that much time to degrade.

Effectiveness of diesel as a weed killer

Diesel, as we have already discussed, is a toxic mode of killing the weeds in your garden. It should not have been opted for as other environmentally friendly alternatives are present in the market. Non-toxic weeds, although needing some extra work, will not kill the other plants 8n your garden, unlike diesel. 

Diesel or any chemical based weed kills the good biota and organisms in the soil that helps in the steady growth of the plants. Other alternatives, such as using boiling water on the weed’s roots, rubbing alcohol, or spraying a solution of salt and vinegar, can all work wonders in the case of the weeds. 

The potential effectiveness of diesel on different types of weeds is huge. Diesel being high in toxic chemical substances is a non- selective plant killer. It can kill any type of weed that comes in contact with it. Apply diesel close to the spot of the roots, and you will notice the weeds dying within 48 hours.

Do not water the area near the treated weeds to prevent them from diluting the other plants. This will ensure that the other plants in the garden are safe with minimal damage to the garden soil.

Diesel is not an environmentally friendly solution. It can greatly affect soil fertility due to its chemical properties. Diesel kills the good organisms in the soil that keeps up the plant’s growth.

Using diesel as a weed killer on a large scale is never a good idea as it may hamper the area’s ecological balance. 

Safety and Legal Considerations

Diesel is a combustible fuel with many hazards that are dangerous for plants, insects, and the ecology as a whole. Diesel, if in any way consumed through the plants, is life taking. Inhaling or ingesting diesel in huge quantities can lead to multiple organ failures among humans.

Therefore, certain specific rules must be followed if one uses diesel as a weed killer. Some of them are mentioned below:

• Diesel is a non-selective plant killer and should not be sprayed near good and healthy plants.
• One should wear a mask before spraying the diesel on the weeds to prevent yourself from inhaling it.

Regarding the legal permissions for using diesel as an herbicide, it is illegal to use diesel. There are restrictions on diesel in many countries, such as the USA, UK, etc. Spraying diesel in the weeds means illegally dumping toxic chemical substances that can harm the environment. If any gardener is seen using diesel in their garden, they will have to pay a huge fine or can even get jailed.
