Query: Plant Disease Detection Using Image Processing and Machine Learning   One of the important and tedious task in agricultural practices is the
detection of the disease on crops. It requires huge time as well as skilled
labor. This paper proposes a smart and efficient technique for detection of
crop disease which uses computer vision and machine learning techniques. The
proposed system is able to detect 20 different diseases of 5 common plants with
