Several viruses are known to infect the plant, including seed-borne strawberry latent ringspot virus, parsnip yellow fleck virus, parsnip leaf curl virus, parsnip mosaic potyvirus, and potyvirus celery mosaic virus. The latter causes clearing or yellowing of the areas of the leaf immediately beside the veins, the appearance of ochre mosaic ...
The virus specifically targets carrots, parsnips, and cilantro but only effects carrot as this is the only host for the vector. This virus alone does not cause symptoms in carrots, but in connection with Carrot red leaf virus (CRLV) causes yellowing, reddening of leaves and yield loss.
Sequivirus is a genus of viruses in the order Picornavirales, in the family Secoviridae.Plants serve as natural hosts. There are three species in this genus. Diseases associated with this genus include: PYFV: vein-yellowing, yellow flecks and yellow/green mosaic symptoms in parsnip, and ‘yellow net', followed by yellow spots and leaf distortion in celery.
Carrot virus Y (CarVY) is a (+)ss-RNA virus that affects crops of the carrot family , such as carrots, anise, chervil, coriander, cumin, dill and parsnip. [1] Carrots are the only known crop to be infected in the field. Infection by the virus leads to deformed roots and discolored or mottled leaves.

Celery mosaic virus (CeMV) is a plant pathogenic virus [1] in the genus Potyvirus and the virus family Potyviridae. In California, mosaic diseases of celery (Apium graveolens) were reported as early as 1922. [2] After some time, it became clear that there were at least two different viruses causing mosaic diseases with similar symptoms in celery.
Cucumber leaves afflicted with various stages of Cucumber mosaic virus. A mosaic virus is any virus that causes infected plant foliage to have a mottled appearance. Such viruses come from a variety of unrelated lineages and consequently there is no taxon that unites all mosaic viruses.
