Pesticides are nothing but strong chemicals that kill the pests.
They are harmful for human also.
While spraying, the pesticide mixes with the air and enters the farmer’s body who is spraying.
Inside the body this chemical gets mixed with the blood and affects the immune system.
As a result the farmer falls ill.
So it is important that the person who is spraying pesticide mush cover his mouth and nose to protect himself from its harmful effect.
