What plants are affected by cucumber mosaic virus?

Tobacco mosaic virus can infect ornamentals and weeds including cucumber, lettuce, beet, pepper, tomato, petunia, jimson weed and horsenettle.

Can FIG mosaic virus spread to other plants?

Generally, production varies due to cultural management not the virus. If the tree fruits reliably, and you enjoy figs, consider keeping the tree. Virus is often, but not always specific to the plant. Fig mosaic won’t “hop” to something else in the garden.

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 tomato plants recover from virus?

A virus disease, TSWV can infect plants in the greenhouse or in the field. Infected plants cannot be cured and should be removed from the garden.

Is it safe to eat squash with mosaic virus?

Are squash and melons affected by mosaic virus safe to eat? “Yes,” says Nebraska Food Safety Educator Carol Larvick, citing information from Minnesota Extension. “These viruses are specific to plants and do not harm humans.

What type of virus can only infect plants?

One class of viruses, the Rhabdoviridae, has been proposed to actually be insect viruses that have evolved to replicate in plants. The chosen insect vector of a plant virus will often be the determining factor in that virus’s host range: it can only infect plants that the insect vector feeds upon.

Do all plant viruses cause diseases in plants?

All types of living organisms including animals, plants, fungi, and bacteria are hosts for viruses, but most viruses infect only one type of host. Viruses cause many important plant diseases and are responsible for losses in crop yield and quality in all parts of the world.

Can plants fight viruses?

Interestingly, plants have an immune system too. In plants and insects, a very effective way to combat a virus is through a process known as gene silencing. This mechanism treats a virus as a gene that is being expressed out of control. Thus, plant cells turn it off by dicing the viral RNA into small pieces.

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.
