Of course you want to get rid of pests quickly, but chemical-laden fungicides are clearly the wrong way. That's why you can read on this page how you can easily banish whitefly from your plants with a specially prepared rapeseed oil solution.
How can you fight whitefly with rapeseed oil?
To combat whitefly with rapeseed oil, mix 30% rapeseed oil with 70% water and spray the affected plant, especially the undersides of the leaves, in the early morning hours every four to five days until the pests disappear.
How does the control with rapeseed oil work?
A mixture of water and rapeseed oil covers your plant like a film. This will not cause any damage. However, the whiteflies no longer receive oxygen and therefore suffocate.
Which cooking oil is suitable?
You can use conventional rapeseed oil from the supermarket for the treatment. It is therefore a very inexpensive method of combating the pest. If you have an oil press, you can of course also make the rapeseed oil yourself.
Make rapeseed oil mixture
- Mix a solution of 30% rapeseed oil and 70% water.
- Pour the solution into a spray bottle.
- Spray the affected plant several times at regular intervals.
The right time for application
Anyone who has ever observed the behavior of whiteflies knows how actively the animals buzz around the plant. It is therefore best to spray the rapeseed solution onto the crop in the early morning hours. On the one hand, the animals are still sluggish and you have a better chance of catching most of them. On the other hand, there is a lower risk of the so-called magnifying glass effect. This is the burning of the leaves in direct sunlight due to small water droplets that refract the light. Apply the rapeseed oil solution approximately every four to five days.
More tips
- Spray the undersides of the leaves primarily.
- Isolate the plant from other plants so that the whitefly does not move.
- Use the rapeseed oil solution as quickly as possible or only make small quantities as the mixture does not last long.
