What causes yellow vein mosaic?
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.
Who has discovered yellow vein mosaic virus for the first time?
35.3. 3 Bhendi yellow vein mosaic virus. BYVMV was first reported by Kulkarni (1924) from Mumbai, India. This virus has been reported in Bangladesh, India, Pakistan, Thailand, Sri Lanka, and China on okra plants (Kulkarni, 1924; Tsai et al., 2013).
Can 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.
How is yellow mosaic virus transmitted?
The virus is transmitted by over 20 species of aphids (e.g., the pea, green peach, and bean aphids). Transmission of the virus to the bean plant occurs within seconds once virus-carrying aphids begin feeding on the crop. Aphids can effectively spread the virus within a field, resulting in high rates of infection.
How can we control yellow mosaic virus?
Seeds are to be treated with insecticides like carbosulfon at 30gm or monocrotophos at 5ml per one kg seed before sowing. Follow crop rotation and maintain soil health management. Grow suitable region wise resistant varieties. Use seeds collected from disease-free plants.
What does mosaic virus do?
THE TOBACCO MOSAIC VIRUS
Tobacco mosaic virus causes a mottled browning of tobacco leaves, and accordingly is of major economic importance. It also infects other crops, most notably tomatoes. The virus is spread mechanically from infected plants to scratched or damaged leaves of normal plants.
Which plant is resistant to yellow mosaic virus?
New breeding lines of soybean having a gene for resistance to yellow mosaic virus from Glycine soja Linn. Sieb. & Zucc. Indian J Agric Sci 54: 1027–1029.
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.
