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.
Does mosaic virus affect humans?
Tobacco mosaic virus (TMV), a widespread plant pathogen, is found in tobacco (including cigarettes and smokeless tobacco) as well as in many other plants. Plant viruses do not replicate or cause infection in humans or other mammals.
Can mosaic virus spread to other plants?
Control your weeds. Some types may serve as hosts for the disease, and when aphids and other insects feed on these plants, they will spread the viruses to your garden plants. To avoid seed-borne mosaic viruses, soak seeds of susceptible plants in a 10% bleach solution before planting.
Can you treat cucumber mosaic virus?
Early season aphid control may help, but there is no known Cucumber Mosaic Virus treatment at the present time. It’s recommended that if your cucumber plants are affected by Cucumber Mosaic Virus, they should be removed immediately from the garden.
Are cucumbers affected by mosaic virus?
Specifically, CMV can cause cucumbers to turn pale and bumpy. The leaves of these plants turn mosaic and their rugosity is often changed, making leaves wrinkled and misshapen. Growth of these plants is usually also stunted and produces few flowers.
Is tomato 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.”
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 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.
Which crop is generally affected by mosaic disease?
mosaic, plant disease caused by various strains of several hundred viruses. A number of economically important crops are susceptible to mosaic infections, including tobacco, cassava, beet, cucumber, and alfalfa.
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).
Can you eat zucchini 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.
How do you prevent tomato mosaic virus?
Destroy any seedlings that appear stunted or distorted and then decontaminate tools and hands. Keep the area around the tomatoes weeded and free of plant detritus to minimize areas the disease can harbor. Control insects as well to lessen the chances of contamination.
Does cucumber mosaic virus affect tomatoes?
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 you get rid of mosaic virus in squash?
Instead, use certified virus-free seeds, choose varieties that are resistant to mosaic, clean gardening tools with a 10% bleach solution between uses, and remove weeds from inside and outside the garden to reduce the amount of pathogen spread by insects.
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).
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.
