Diagnosis of plant diseases is based on the evaluation of all factors such as environmental conditions, disease symptoms in the plant, some clues about the pathogen, characteristics of the place of production, plant variety or species. Well-equipped knowledge and the use of multiple techniques are needed for accurate and rapid diagnosis of plant diseases. ELISA (Enzyme-linked Immunosorbent Assay) is the most common method used for the detection of plant pathogens.
