When symptoms are present, confirm the causal agent with laboratory diagnoses. Symptoms of this disease may be suppressed, indistinguishable from other diseases or inconspicuous under unfavorable climatic conditions or plant physiological stress, requiring thorough laboratory analysis. Prolonged periods of latency resulting in asymptotic plants has not been documented for this pathogen, though the period from infection to symptom expression may vary with climatic conditions, plant genetics, physiological stress and plant pathogen strain. Literature showing that random sampling of apparently healthy plants to detect latent populations of this pathogen has not been found.
