Plant Diagnostics: Importance
Plant diseases spread as quick as human
diseases
Infected plants can not be saved.
Quick plant pathogen diagnosisQuick on site diagnosisSpecialized lab
The United States crops are a billionaire business

Signs and SymptomsAt a glance, take a look in signs and symptoms.
Pseudomonas syringae pv. tomato
Signs: Presence of the pathogen (bacterial cells)
Signs and symptoms may give a guidance to plant pathologist.
Symptoms: responses of the plant.

Different techniques for Diagnosis
Symptoms and signs are not the only tool to
diagnostic a plant disease.
DNA RNA Proteins
Molecular Techniques:Polymerase Chain
Reaction (PCR)
Immunological tests:Immunostrips
Agglutination tests
Immunological tests:Immunostrips
Agglutination tests
