Can plants survive mosaic virus?
Tobacco mosaic is caused by Tobacco mosaic virus (TMV), the first virus ever identified. Numerous variants (strains) of the virus have subsequently been described. TMV survives in infected plants (including viable seeds), as well as in debris from these plants.

What Causes Mosaic Disease? Like viruses that affect humans and animals, Mosaic virus is contagious and can be spread from plant to plant via insects, dirty hands and tools, infected pots and potting soil, and close proximity with other infected plants.
How do I get rid of squash mosaic virus?
Using insecticides to manage cucumber beetles can help manage SqMV infection in areas where the virus is present. Virus-free seed is the primary method used to manage SqMV. If feasible, roguing virus-infected plants early in the season can help reduce the spread of viruses within a planting.
