- Chlorosis and patterned leaves. Yellow wavy lines, ring spots, or mosaic patterns will spread through the foliage.
- Leaves will display notches.
- Necrotic lesions.
- Leaf and stem deformities, especially in younger plants.

- Reduced vigor.
How to prevent
Due to the likelihood of cross-contamination through infected sap, clean tools and hands when handling plants are a must, as well as regular sanitization between plants when pruning and cutting for propagation. Seeds can also be infected, so try choosing healthy seeds.
If possible, and especially with ornamental plants, choose a similar one that isn't susceptible to this virus. When acquiring a new specimen, quarantine it until you're sure they're healthy and not infected.
Unfortunately, once a plant is infected, it will remain infected indefinitely. This virus can't be eradicated, and there isn't much treatment besides good care practices and prevention techniques. Infected plants should be removed and burnt or buried deep, as well as all infected debris.
Pesticides or any other chemicals are not effective against this virus.
