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.

The pathogen has been reported on watermelon, but seed as a pathway has not been proven. Movement of the pathogen to seedlings was not shown to occur in controlled experiments. Seed as a pathway for transmission of Xanthomonas cucurbitae appears to be minor or insignificant. Currently seed as a pathway has only been shown on species of Cucurbita (pumpkin).
