What is the disease caused by TMV?

Written by Editorial Team | Last Updated: August 2026

Tobacco mosaic virus (TMV) is a highly stable plant pathogen that causes tobacco mosaic disease, which affects a wide variety of economically important crops, including tobacco, tomatoes, peppers, cucumbers, and various ornamental plants. The disease is characterized by distinct visual symptoms on foliage, including characteristic light and dark green mottling, mosaic patterns, leaf curling, stunted plant growth, and distorted fruit development. Because the virus is extremely contagious and can persist for years in dried plant debris, soil, or on contaminated tools, it can devastate agricultural yields if strict sanitation and resistant crop strains are not implemented.
