The Evolution of Pesticides
Due to the extraordinary increase in pest and disease outbreaks in agricultural crops and the atmosphere, along with the decrease in production, the human is in danger.
According to a rough estimate, pest and disease outbreak affects 25-46% of the total production.
Only 4 crore rupees per year have been estimated in India due to rust disease.
According to the new data, there is a loss of about 5 crores Rupees per annum due to Powdery Mildew disease.
