Cucumber Mosaic Virus

CMV - Tomato

Symptom: Stringy and rigid leaflets (not to be confused with hormone damage), puckered and checkered leaflets, blistered fruit with yellow rings or swirls, stunted plants in the case of early attacks.
Advice: Remove weeds (which are reservoirs for viruses) around the plants. Create a trap crop around the field. Eliminate aphids, destroy suspicious plants,
protect young plants in a nursery and regularly clean all tools.
