PCR-based DNA array technology is one of the most suitable techniques to detect and identify multiple pathogens in a single assay. Out of the different array platforms that currently exist, membrane-based DNA macroarrays are the most convenient for plant disease diagnosis because of low costs, great sensitivity, and modest equipment requirements. Here we describe a protocol for routine detection of plant pathogens using DNA macroarrays, i.e., from sampling to analysis of hybridization results. Diagnosis can be completed within 36 h after sample collection.
