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.
What plants get cucumber mosaic virus?
Since then, it has been found to infect a great variety of other plants. These include other vegetables such as squash, melons, peppers, tomatoes, beans, carrots, celery, lettuce, spinach, beets, many ornamentals and bedding plants, such as Narcissus, and various weeds.
What plants does mosaic virus infect?
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.
Which crop is affected by mosaic disease?
A number of economically important crops are susceptible to mosaic infections, including tobacco, cassava, beet, cucumber, and alfalfa.
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.
How do I get rid of cucumber mosaic virus?
- Purchase virus-free plants.
- Maintain strict aphid control.
- Remove all weeds since these may harbor both CMV and aphids.
- Immediately set aside plants with the above symptoms and obtain a diagnosis.
- Discard virus infected plants.
- Disinfest tools used for vegetative propagation frequently.
Can a plant survive mosaic virus?
Plant virus-resistant varieties in your garden. Resistant varieties of tomatoes have yet to be developed for cucumber mosaic virus, but tomatoes that are resistant to tobacco mosaic virus may have some slight resistance to cucumber mosaic virus as well.
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 virus?
Where does cucumber mosaic come from? 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.
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.”
Can tomatoes get mosaic virus?
For example, tomato mosaic virus most often infects tomatoes, but can also infect pepper, potato, apple, pear, cherry and numerous weeds, including pigweed and lamb’s quarters. Tobacco mosaic virus can infect ornamentals and weeds including cucumber, lettuce, beet, pepper, tomato, petunia, jimson weed and horsenettle.
Does mosaic virus stay 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.
Can peppers get mosaic virus?
Mosaic is a viral disease that affects quality and reduces yield in a wide variety of plants, including sweet and hot peppers. Once infection occurs, there are no cures for mosaic virus on pepper plants, which is spread by pests. Even fungicides are of no use against pepper mosaic virus.
Does cucumber mosaic virus stay in the 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.
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.
What is CMV plant?
Cucumber mosaic virus (CMV) is an aphid-borne virus that infects a wide range of plant species including vegetable crops and weeds.
