Quick Answer: How do you control cucumber mosaic virus?

How do you kill mosaic virus?

There is NO CURE for the Mosaic Virus. Once it infects a plant, there is no saving it. Your best course of action is to remove the entire plant completely, and destroy it. Be sure to clean and disinfect any garden tools used during the clean-out.

What prevents 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.

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.

Can cucumber mosaic virus spread to other plants?

Cucumber mosaic virus can infect plants from over forty families, including vegetable crops like tomato, lettuce and spinach, flower crops like gladiolus, petunias, impatiens and rudbekia, and a wide variety of weeds. All of the mosaic viruses can also infect weeds in the cucurbit family.

How do you control plant viruses?

Disease control is based on two strategies: i) immunization (genetic resistance obtained by plant breeding, plant transformation, cross-protection, or others), and ii) prophylaxis to restrain virus dispersion (using quarantine, certification, removal of infected plants, control of natural vectors, or other procedures).

Does bleach kill mosaic virus?

Hu et al. (33) found that undiluted skim milk inactivated Cymbidium mosaic virus (CyMV) on a local lesion host and commercial bleach inactivated both CyMV and Odontoglossum ringspot virus (ORSV) at 10% or 20% concentration.

Can plants recover from virus?

Virus-induced diseases cause severe damages to cultivated plants resulting in crop losses. Interestingly, in some cases, the diseased plants are able to re-gain health, further grow and develop normally.

How long does it take for mosaic virus to appear?

Symptoms of TMV-infection in susceptible plants:

Symptoms will appear in 1-3 weeks, depending on the variety and concentration of virus in the inoculum. These new leaves on infected tomato plants will exhibit a mottle or green and yellow color pattern and may be distorted. The plants also may be stunted (Figure 11).

How quickly does mosaic virus spread?

Comments on the Disease

Cucumber mosaic virus is spread from plant-to-plant by many species of aphids. Aphids only retain the ability to transmit these viruses for very short periods of time (minutes to a few hours). Thus, spread is often very rapid and local.

What is the cause of cucumber mosaic virus?

What causes Cucumber Mosaic disease is the transfer of the virus from one infected plant to another through the bite of an aphid. The infection is acquired by the aphid in just one minute after ingestion and is gone within hours.

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.

How can we control yellow mosaic virus?

Control measures:

— Infected plants should be removed. — Remove and destroy disease-affected leaves/plants from crop fields to avoid secondary spread. — Destroy host weeds. Intercrop with non host crops like sorghum, pearl millet and maize.

What are the symptoms of cucumber mosaic virus?


  • Yellowish patches or green and yellow mottling on leaves.
  • Leaves curl downwards and are distorted and reduced in size.
  • Plants are stunted due to a shortening of the internodes (lengths of stem between leaves)
  • Reduction in yields and distorted fruit.
  • In flowers white streaks known as ‘breaks’ appear.

What cucumbers are resistant to mosaic virus?

Cucumber mosaic virus is one of the most recurrent viruses infecting pepper in South Korea (Choi et al., 2005). The Chinese C. annuum variety “Likeumjo” is resistant to CMV-P0 (Kang et al., 2010) and is a rare CMV resistance source controlled by a single dominant gene, Cucumber mosaic resistant 1 (Cmr1).

Is mosaic virus harmful to plants?

“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.”
