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.
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.
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.
Can 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.
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.
What plants are affected by mosaic virus?
Mosaic viruses affect a wide range of edible crops – alfalfa, apples, beans, celery, corn, cucumbers, figs, peppers, spinach, tobacco and tomatoes are some of the more common ones. They can also infect ornamental plants like abultilon, delphinium, gladiola, marigold, petunia and one of the most notable, roses.
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.”
