Western celery mosaic virus

Celery mosaic virus is a plant pathogenic virus in the genus Potyvirus and the virus family Potyviridae. As the name suggest, celery is the most common host, but it has also been known to infect other plants in the Apiaceae family including carrot, coriander, parsley, parsnip and dill. The virus is not reported to be seedborne; it is vectored by aphids.[1]

Symptoms[edit | edit source]

Disease symptoms caused by celery mosaic virus include yellowing of foliage, mosaic and/or mottling patterns on leaves, vein clearing, and curled, crinkled, or otherwise distorted foliage. On older leaves necrotic leaf spots may develop. Plants are sometimes stunted. Outer petioles grow horizontally, giving the plant a flattened appearance. Certain strains of the virus may cause more severe symptoms than other strains.[1]

Control[edit | edit source]

Cultural Control[edit | edit source]

For celery mosaic, a host-free period of at least 2 to 3 months (in which celery is not being grown in the area) greatly reduces the incidence of celery mosaic. Eliminate weed hosts like wild celery and wild parsnip, especially during the celery-free period.[1]

Organically Acceptable Methods[edit | edit source]

Cultural controls are acceptable for use on organically grown produce.[1]

Treatment Decisions[edit | edit source]

Chemicals are not effective against plant viruses. Insecticides for controlling the vector are not effective in preventing virus infections.[1]
