Agriculture can be contemplated as the “vertebral column” of the human life and has substantial control on country’s economy. In the aim of enhancing agricultural sustainability, effectiveness and plant health, cultivators are continuously innovating high technical and scientific estimation. Remote sensing is a quick, broad-spectrum, and sophisticated approach for analysing the spectral properties of earth surfaces from a variety of distances, ranging from satellites to ground-based platforms. In this process, the information can be obtained without coming into direct contact with the object. One of the main focus of remote sensing in agriculture production of crop including crop protection from various diseases and pests. Remote sensing technique is very helpful for incredibly spatial diagnostic results and its execution in agriculture, more sustain and safe by evading expensive and excessive use of different pesticides, fungicides etc. in production of crops.
