Disease?

[Roastbeast]

One of my plants has this pattern on almost all the leaves, could anyone tell me what it is? Thanks

Looks like Mosaic virus.

Definitely viral. Could also be Tobacco Etch Virus (TEV), which overwinters in solanaceous (related to tobacco) weeds, and is transmitted by aphids.

Whoa-oh... Well that plant was discarded and the greenhouse it was in won’t be used for tobacco again anyway, but is there any other action I should take? Does it mean anything for the surrounding plants?

The effect of most virus infections on tobacco plants depends on when during the growing season the plant is infected. Infection of a new transplant usually results in serious impact to growth. Infection in mid-season or later will often simply injure one or a few leaves. The tobacco is still smokable. I have watched for spread to adjacent leaves or adjacent plants, and have not seen that. In general, virus infections depend on a vector for transmission. Insect vectors peak at specific times. Human vectors (carrying TMV, for example, on fingers or tools) tend to be sporadic in their behavior.

For me, tobacco virus infections have meant only that the productivity of the affected plants is somewhat reduced. I rarely pull out a plant, or even remove an affected leaf.

EDIT: I should add that when I am removing suckers, I remove them from a virus infected plant last. Then I wash my hands.

Thanks gentlemen. Those are invaluable links, much appreciated.
Jeez, viruses wherever a guy goes nowadays, not even safe in the greenhouse
