Turnip Mosaic Virus
Return to diseases
Turnip mosaic (Turnip mosaic virus). All cole vegetables are susceptible, and the pathogen is aphid-transmitted. Symptoms include variegated color patterns (mosaic), necrotic ringspots, and distortion on foliage. Weeds and cole crops are reservoirs of the virus.

- Insect control (will not impact initial infections but will help reduce secondary spread).
