How do I get rid of cucumber mosaic virus?

Management

  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.
  5. Discard virus infected plants.
  6. Disinfest tools used for vegetative propagation frequently.

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 causes cucumber mosaic?

Cucumber mosaic is caused by Cucumber mosaic virus (CMV) which can overwinter in susceptible biennial or perennial weeds, as well as in perennial agricultural crops (e.g., alfalfa) and perennial herbaceous and woody ornamentals.

Who spread the cucumber mosaic virus?

Spread: This virus is spread by several aphid vectors. Aphids aquire and transmit virus particles by probing and/or feeding on plant tissues. An aphid can transmit the virus to susceptible plants for up to two hours after acquiring the virus from an infected plant.

Does cucumber mosaic virus stay in soil?

If there’s any good news here it’s that unlike some other mosaics, Cucumber Mosaic Virus can’t be passed along through seeds and won’t persist in plant debris or soil.

Does mosaic virus stay in the 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.

It can be transmitted from plant to plant both mechanically by sap and by aphids in a stylet-borne fashion. It can also be transmitted in seeds and by the parasitic weeds, Cuscuta sp. (dodder).

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.

How long does mosaic virus last in soil?

These investigations have shown that the virus may survive in soils for periods of 1 year or more, but that it is subject to relatively rapid inactivation under certain natural conditions.

Can cucumber mosaic virus affect tomatoes?

The disease affects a number of important vegetables and ornamentals including tomato, pepper, cucumber, melons, squash, spinach, celery, beets, and petunia. Tomatoes infected with the cucumber mosaic virus develop a slight yellowing and mottling of the older leaves.

How do you test for cucumber mosaic virus?

Cucumber mosaic virus (CMV) is a widespread plant virus infecting important vegetables, plantation and flower crops. Currently, CMV is detected by enzyme-linked immunosorbent assays (ELISA) and reverse transcription-polymerase chain reaction (RT-PCR) assays. ELISA requires polyclonal antibodies and is time-consuming.

Which crop is reservoir 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.

Why are my cucumber plant leaves turning yellow?

How do you treat Dahlia virus?

When these tiny insects penetrate the dahlia’s epithelium, they ingest the mosaic virus along with their meal of sap. As they move from plant to plant, the virus is spread to uninfected dahlia plants. Adopting a spray program to eliminate aphids is effective. Organic growers can use insecticidal soaps.

What determine the severity of symptoms of Mosaic?

Disease severity generally depends upon the host genotype, and is usually more severe on susceptible than on resistant genotypes (Hahn et al., 1980; Jennings, 1994; Thresh et al., 1994).

How do you control viruses on tomato plants?

Soak seeds in a 10% solution of trisodium phosphate (Na3PO4) for at least 15 minutes. Heat dry seeds to 158 F and hold them at that temperature for two to four days. Hot water treatment is not adequate for some tomato viruses.
