Pests and diseases are part of every ecosystem. They are significant issues in crop protection. Farmers use different methods to control pests and diseases to reduce their effects on crops. But lack of knowledge about these pests and diseases lead to faulty and inefficient methods to deal with them. Therefore, to deal with this problem we are developing a Pest Detection System using Image Processing. With the detection of pest, we provide the proper solution in terms of fertilizer and many more things.
