This pathogen is not quaranted anywhere in the world (ALTEDA-1). This pathogen has been reported in MX.

The main host of Alternaria dauci. is carrot. Other umbielliferous crops are susceptible in nature, celery, parsley, parsnip. Other crops, cabbage, tomato, lettuce, radish and cucumber, were attacked in laboratory studies, but not considered natural hosts.

The period from infection of plant tissue to symptoms is usually short, under favorable conditions. This period may increase when conditions are not favorable, with genetic resistance, other disease or pest pressure, or physiological stress. Symptoms may also be inconspicuous, masked, or atypical under similar conditions or stress. When symptoms are present, confirm the causal agent with laboratory diagnoses. Prolonged periods of latency resulting in asymptotic plants has not been documented for this pathogen. Literature showing that random sampling of apparently healthy plants to detect latent populations of this pathogen has not been found.
