Tobacco Mosaic Virus (TMV) has a very wide host range including tobacco, vegetables (especially in the Solanaceous family), and many ornamental species. Unlike many plant viruses, it is not vectored by aphids, thrips, or leafhoppers; TMV spreads very efficiently in plant sap. This virus is transmitted by tools and workers as well as plant to plant contact where there wounds caused by handling or insects. TMV can also persist in tobacco products and workers should wash their hands after using tobacco products. There is no cure or treatment for TMV. Discard infected plants and thoroughly disinfest growing areas.
