How can you tell if a cucumber is mosaic virus?

How do I know if my cucumber has a virus?

Virus-infected leaves often have a mottling or mosaic pattern in shades of green and yellow. This mosaic can be very distinct and obvious, or subtle. Leaves are often distorted or deformed. They may be puckered, cupped under, have deep lobes, or appear thin and string-like.

Can you eat cucumbers with mosaic virus?

Yes, you can eat squash and melons that are infected with mosaic virus. These viruses are not harmful to humans and do not cause the fruit to rot. Often the discoloration is only skin deep. In cases where fruit are severely distorted, the texture of the fruit may be affected and may not be desirable for eating.

What is the host of cucumber mosaic virus?

It has a host range of more than 1,200 species, and is transmitted by many species of aphids, as well as cucumber beetles. Vegetable hosts include carrot, celery, cucurbits, legumes, lettuce, onion, pepper, spinach, tomato, and rarely potato. Many woody and non-woody ornamentals are also hosts.

How do I get rid of cucumber mosaic virus?

There are no chemicals that cure a CMV-infected plant, nor any that protect plants from becoming infected.

  1. Purchase virus-free plants.
  2. Maintain strict aphid control.
  3. Remove all weeds since these may harbor both CMV and aphids.
  4. Immediately set aside plants with the above symptoms and obtain a diagnosis.

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.

How do you test for tobacco mosaic virus?

Currently, enzyme-linked immunosorbent assay (ELISA) and polymerase chain reaction (PCR) are the most commonly used methods to detect TMV in plants2. However, the processes of those methods are quite time-consuming, complex, and even challenging since the TMV may distribute unevenly in plant tissues at low level.

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.”
