Can cucumber mosaic virus spread to other plants?

Can mosaic virus spread to other plants?

If the sap contains TMV, it can be introduced into other plants when those come in contact with this sap. Sucking insects such as aphids do not spread TMV. Chewing insects such as grasshoppers and caterpillars occasionally spread the virus but are usually not important in spread.

Does mosaic virus stay in soil?

The virus often appears following cool conditions that favor aphid flights. 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.

Is mosaic virus harmful to humans?

“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 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.

How do you treat tomato mosaic virus?

Destroy any seedlings that appear stunted or distorted and then decontaminate tools and hands. Keep the area around the tomatoes weeded and free of plant detritus to minimize areas the disease can harbor. Control insects as well to lessen the chances of contamination.

How can we prevent tobacco mosaic virus?

To control the spread of TMV, farmers must: 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.

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.
