Frequent question: How does cucumber mosaic virus infect plants?

How does cucumber mosaic virus affect plant growth?

Cucumber mosaic virus (CMV) is one of the most common plant viruses, causing yellow mottling, distorted leaves and stunted growth in a wide range of garden plants, not just cucumbers.

How do you treat mosaic virus in plants?

There are no cures for viral diseases such as mosaic once a plant is infected.

  1. Fungicides will NOT treat this viral disease.
  2. Plant resistant varieties when available or purchase transplants from a reputable source.
  3. Do NOT save seed from infected crops.

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.

Can you cure cucumber mosaic virus?

There are no chemicals that cure a CMV-infected plant, nor any that protect plants from becoming infected. Purchase virus-free plants. Maintain strict aphid control. Remove all weeds since these may harbor both CMV and aphids.

Where does cucumber mosaic virus come from?

CMV is mainly transmitted by aphids, but it can also be mechanically spread by humans in some cases. However, the mechanically spreading of this virus is not as common as the case of other virus (such as Tobacco Mosaic Virus, TMV), because CMV is not a very stable virus.

Is cucumber mosaic virus harmful to humans?

“Yes,” says Nebraska Food Safety Educator Carol Larvick, citing information from Minnesota Extension. “These viruses are specific to plants and do not harm humans. The presence of mosaic won’t cause fruits to rot prematurely but severely distorted fruit will have a different texture, so use your own judgement.”

Can tomatoes get cucumber mosaic virus?

Tomatoes infected with the cucumber mosaic virus develop a slight yellowing and mottling of the older leaves. Expanding leaves typically become twisted, curl downward, and develop a “shoestring” appearance as a result of a restriction of the leaf surface to a narrow band around the midrib of the leaf.

How can we prevent the tobacco mosaic virus from spreading?

Controlling the spread of tobacco mosaic virus

wash their hands after handling infected plants. wash tools that have come into contact with infected plants in detergent or bleach. rotate the crops they grow in a contaminated field – they must not grow tobacco or tomato plants in the field for at least two years.

Does mosaic virus live in soil?

Unlike TMV (tobacco mosaic virus), CMV is not seedborne in tomato and does not persist in plant debris in the soil or on workers’ hands or clothing. The occurrence of this virus is erratic and unpredictable; consequently, control of this disease can be difficult.
