Turnip Mosaic Virus



Found worldwide

Damage Symptoms

Turnip Mosaic Virus (TuMV) infects most cruciferous plants, but is most damaging in Chinese cabbage, turnip, mustard, and radish. The most common symptom in these crops is a distinct mosaic of light and dark green colors in the leaves. Depending upon the virus strain and the crop species, necrotic streaks, flecks, or ringspots may also occur. Necrotic spots and ringspots are the primary symptom in common cabbage, but the severity of symptoms is cultivar dependant.

Conditions for Development

The virus is transmitted by several species of aphids. The presence of virus source plants, i.e. infected crops or weeds, and conditions that favor migrating aphid populations will lead to a high incidence of TuMV infection.
