Mosaic is the symptom of a number of plant viruses, perhaps the most familiar being Tobacco Mosaic Virus, which affects a wide range of hosts.
[edit] Symptoms and Signs
Irregular blotching of differently colored patches on the leaf, often with different colors in interveinal parts of the leaves.
[edit] Transmission
Like any virus, transmission requires a vector (usually aphids) but human activity (such as pruning or grafting) can also transmit the viruses.

[edit] Controls
- Exclusion: Control vectors and alternate (weedy) hosts, keep cutting tools sterile.
