What is causative agent of yellow vein mosaic of Bhindi?

This disease is caused by a complex consisting of the monopartite begomovirus Bhendi yellow vein mosaic virus (BYVMV, family: Geminiviridae) and a small satellite DNA beta component. BYVMV can systemically infect bhendi upon agroinoculation but produces only mild leaf curling in this host.

How do I get rid of mosaic virus?

How is cassava harvested?

Cassava is traditionally harvested by hand lifting the lower part of stem and pulling the roots out of the ground, then removing them from the base of the plant by hand. The upper parts of the stems with the leaves are usually removed before harvest. Levers and ropes can be used to assist harvesting.

Do Viruses Kill Plants?

Viruses rarely kill plants, and usually plants can tolerate infections if they are grown well and kept in good health and vigour. Viruses have no means of movement and generally rely on other organisms (vectors) to transmit them from diseased to healthy plants.

How can we prevent tobacco mosaic virus?

Controlling the spread of tobacco mosaic virus

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.

What are the symptoms of tobacco mosaic virus?

Symptoms associated with TMV infections:

stunting.
mosaic pattern of light and dark green (or yellow and green) on the leaves.
malformation of leaves or growing points.
yellow streaking of leaves (especially monocots)
yellow spotting on leaves.
distinct yellowing only of veins.

How does the disease spread from one plant to another?

All viruses that spread within their host tissues (systemically) can be transmitted by grafting branches or buds from diseased plants on healthy plants. Natural grafting and transmission are possible by root grafts and with parasitic dodder (Cuscuta species). Vegetative propagation often spreads plant viruses.

How does yellow vein mosaic of Bhindi spread from one plant to another?

Bhendi yellow vein mosaic virus (BYVMV) or okra yellow vein mosaic (OYVMV) is a viral disease caused by monopartite Begomovirus affecting okra plants. ... This disease is transmitted by whitefly.

Is tobacco mosaic caused by fungi?

The tobacco mosaic virus (TMV) infects tobacco plants and other closely related species, such as tomatoes and peppers. TMV is transmitted by contact between plants, either naturally or on the hands of farmers or contaminated clothes or tools.

How can we prevent cucumber mosaic virus?

Management

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.

Does mosaic virus stay in soil?

Tomato mosaic virus and tobacco mosaic virus can exist for two years in dry soil or leaf debris, but will only persist one month if soil is moist. The viruses can also survive in infected root debris in the soil for up to two years.

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. 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.

Can a tobacco mosaic virus infect a human?

Accordingly, they are not considered harmful for humans. However, a few studies questioned the certainty of this paradigm. Tobacco mosaic virus (TMV) RNA has been detected in human samples and TMV RNA translation has been described in animal cells.

Is TMV a virus?

TMV is a single-stranded RNA virus that commonly infects Solanaceous plants, which is a plant family that includes many species such as petunias, tomatoes and tobacco.

Does cucumber mosaic virus live in soil?

Great for the aphid, but really unfortunate for the hundreds of plants it can bite during those few hours. 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.
