Remote Sensing: A Promising Strategy for Crop Pest Management

An overview of the historical and contemporary approaches to remote sensing techniques and their uses, particularly for managing plant diseases and insect pests, is given in this article. The technique of measuring, logging, and analysing the electromagnetic radiation emitted and reflected from the ground target is essential to remote sensing. Applications of remote sensing rely on the spectral behaviour of living things. The detection, prediction, and control of crop pests on various fruit orchards and crops are now accomplished with the help of remote sensing. These tools’ primary goals were to gather information that would aid in managing insect pests and reducing the environmental contamination caused by chemical pesticides. Through the use of multi-spectral systems that rely on colour changes in canopy semblance over time, it has also been utilised to assist farmers in the early diagnosis of mite infestation in cotton fields. By quickly and accurately predicting the presence of specific crop pests, remote sensing helps reduce pest damage and management expenses.
