In this modern time, the farmer can't imagine agriculture without pesticides but it doesn't mean that it is not possible while many states in India and many countries adopt organic agriculture. In India, Sikkim is the first state which adopts organic agriculture.

So if agriculture is possible without pesticides why we use them because of high production and instant results. or we can say for high population in our country and it is important to feed them. so we require high production in small land without any damage.
