It is called an Electrostatic Air Assisted Sprayer. The device is not as big as its name. It is a type of electrostatic sprayer that can be operated while held in the hand.
What is the specialty of an electrostatic sprayer, you ask? They have two areas of specialization. It sprays much smaller particles than normal sprayers. Their size will be only less than 100 microns.
Another key feature is that these particles can be given an electric charge. Liquid particles that acquire a positive charge using electrostatic technology are better absorbed by the leaves etc., on which they fall.
Fine spray particles
The particles sprayed are much smaller than normal sprayers and their size will be only less than 100 microns.
Electric charge
The liquid particles can be given a positive charge using electrostatic technology.
Since the earth has a negative charge, the crops that fall there will also have a negative charge. Particles with a positive charge stick well to plants with a negative charge. It is absorbed and protected.
✨ Key point: Compared to normal sprayers, a smaller amount of medicine is sufficient. This is because the medicine sticks precisely to the leaves without any loss.
In foreign countries, large sprayers are being used. They cost at least two lakh rupees. However, the researchers who designed the portable electrostatic sprayer, which costs only less than 10,000 rupees, are Dean Spare Doctor, Professor P. L. Violin, Ph.D. (D.) Raji James from the College of Agricultural Engineering at Kerala Agricultural University.
🔬 A device suitable for spraying that can reduce human workload. It is useful, says Prof. Violin.
It will help to spray all kinds of pesticides on flowering plants and others in the yard. Since it is an electric sprayer that enables low-volume spray applications, even if the liquid is expensive, the cost of operating this device will be lower. It will also last comparatively longer.

The process of transferring the manufacturing technology of this device, which guarantees better spraying at a low cost, has just begun. We will have to wait until commercial production begins. Therefore, Prof. Violin has informed that they are ready to build and provide these accordingly.

What is an electrostatic air assisted sprayer?
An electrostatic air assisted sprayer is a handheld electrostatic sprayer that sprays very fine liquid particles. According to the article, the particles are less than 100 microns and can be given a positive electric charge, helping them stick better to negatively charged plant surfaces.
How does electrostatic spray stick better to leaves?
The sprayer gives liquid particles a positive charge using electrostatic technology. Since the earth has a negative charge, crops also have a negative charge. The positive particles stick well to plants with a negative charge, so the spray is better absorbed and protected on leaves.
Does this sprayer reduce pesticide use?
Yes. Compared to normal sprayers, a smaller amount of medicine is sufficient because the medicine sticks precisely to the leaves without much loss. This makes the electrostatic air assisted sprayer useful for low-volume spray applications, especially when the spraying liquid is expensive.
How much does the portable electrostatic sprayer cost?
The article says large sprayers used in foreign countries cost at least two lakh rupees. The portable electrostatic sprayer designed by researchers from Kerala Agricultural University costs only less than 10,000 rupees, making it a lower-cost option.
Who designed this portable electrostatic sprayer?
The researchers named in the article are Dean Spare Doctor, Professor P. L. Violin, Ph.D. (D.) Raji James from the College of Agricultural Engineering at Kerala Agricultural University. Prof. Violin also says the device is useful for spraying while reducing human workload.
Can this sprayer be used in home yards and flowering plants?
Yes. The article specifically mentions that it will help to spray all kinds of pesticides on flowering plants and others in the yard. Because it is handheld and supports low-volume spraying, it is suitable for smaller areas where precise spray application is useful.
