Abundant use of chemicals such as bacteri- cides, fungicides, and nematicides to control plant diseases are causing adverse effects to many agroecosystems. Precision plant protection offers a non-destructive means of managing plant diseases based on the concept of spatio-temporal variabil- ity. Global Navigation Satellite System (GNSS) and Geographic Information System (GIS) allow for assessment of feld heterogeneity due to disease problems and can enable site-specifc intervention. Similarly, hyperspectral remote sensing is a cutting-edge spectral approach for plant diseases detection. The main aim of pre- cision plant protection is to signifcantly reduce the injudicious use of chemical inputs and hence the adverse impact of chemicals to the environment. This chapter provides some insights into the deployment of site- and time-specifc approaches to manage plant disease problems in a balanced and optimized manner.
