What is tobacco mosaic disease caused by?

The tobacco mosaic virus infects tobacco and lots of other closely related species like tomatoes and peppers. It is transmitted by contact between plants, either naturally or on the hands of farmers. It infects the chloroplasts of plant leaves and changes their colour from green to yellow or white in a mosaic pattern.

What type of virus is tobacco mosaic virus?

TMV is a single-stranded RNA virus that commonly infects Solanaceous plants, which is a plant family that includes many species such as petunias, tomatoes and tobacco.

Frequently wash your hands and disinfect garden tools, stakes, ties, pots, greenhouse benches, etc. (one part bleach to 4 parts water) to reduce the risk of contamination. Avoid working in the garden during damp conditions (viruses are easily spread when plants are wet). Avoid using tobacco around susceptible plants.

Tomato mosaic virus and tobacco mosaic virus can exist for two years in dry soil or leaf debris, but will only persist one month if soil is moist. The viruses can also survive in infected root debris in the soil for up to two years.

What are the symptoms of tobacco mosaic virus?

Symptoms associated with TMV infections:stunting.mosaic pattern of light and dark green (or yellow and green) on the leaves.malformation of leaves or growing points.yellow streaking of leaves (especially monocots)yellow spotting on leaves.distinct yellowing only of veins.
