How can we control yellow mosaic virus in soybeans?
Management
- Use healthy/certified seeds.
- Keep the field free from weeds.
- Rogue out infected plants and burn them.
- Two foliar sprays of Thiamethoxam 25 WG @ 100 g/ha or Methyl demeton 800 ml/ha at 30 and 45 days after sowing to control the vector.
Which vector is responsible for transmission of soybean mosaic virus?
The virus is transmitted by aphids and also seed-borne at a rate less than 5% in most varieties. Environmental conditions favoring aphid reproduction can favor this disease if the virus is present to be spread.
Is soy virus resistant?
of Nebraska researchers are generating transgenic soybean plants that confer resistance to all three viruses with a single transgene. Greenhouse experiments indicate that these transgenic plants are highly resistant to AMV, BPMV and SMV, even when all three viruses are introduced into the plants simultaneously.
How is TMV transmitted?
TMV is very easily transmitted when an infected leaf rubs against a leaf of a healthy plant, by contaminated tools, and occasionally by workers whose hands become contaminated with TMV after smoking cigarettes. A wounded plant cell provides a site of entry for TMV.
How is yellow mosaic virus treated?
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.
Which of the following organism causes bean mosaic disease in plant?

What does mosaic virus do?
The mosaic virus is a parasite that destroys plants, gardens, and crops down to their molecular level. Once a plant contracts the mosaic virus, the infected plant can then spread the virus to other plants and even affect an entire harvest if left untreated.
What is a viral disease of plant?
The Top 10 list includes, in rank order, (1) Tobacco mosaic virus, (2) Tomato spotted wilt virus, (3) Tomato yellow leaf curl virus, (4) Cucumber mosaic virus, (5) Potato virus Y, (6) Cauliflower mosaic virus, (7) African cassava mosaic virus, (8) Plum pox virus, (9) Brome mosaic virus and (10) Potato virus X, with …
Where is TMV found?
The virus particles are found in all parts of the plant except the few cells at the tips of the growing points. Infected stock plants should be discarded immediately. TMV can also survive outside the plant in sap that has dried on tools and other surfaces.
Where is TMV most common?
TMV is feared in many Asian countries (China, Thailand, Vietnam …) and Oceania (Indonesia, Australia …). Many countries in the Americas are highly infected (Argentina, Brazil, some U.S. states).
How do you control mosaic disease?
How to Control Mosaic Viruses
- Remove all infected plants and destroy them. Do NOT put them in the compost pile, as the virus may persist in infected plant matter.
- Monitor the rest of your plants closely, especially those that were located near infected plants.
- Disinfect gardening tools after every use.
What causes yellow mosaic virus?
Yellow mosaic disease of many legumes is often transmitted by silverfly (Bemisia tabaci).
What causes bean common mosaic virus?
BCMV belongs to the potyvirus group and is serologically related to them, especially to Bean Yellow mosaic Virus (BYMV). This virus is spread between production areas and between seasons, especially in infected seed. The most important vectors are aphids, but also pollen, and mechanical transmission.
What causes bean mosaic virus?
The virus can infect few plants beside dry bean. The virus can be transmitted mechanically by plant-to-plant abrasion and equipment. The virus is disseminated among fields by viruliferous aphids, pollen, movement of contaminated seed, and by movement of contaminated equipment between fields.
What is bean golden mosaic virus?
Bean golden mosaic virus (BGMV) is a single-stranded DNA virus (family Geminiviridae, genus Begomovirus) whose genome has two components of about 2.6 kb in length each, typical of the New World geminiviruses (Gilbertson et al. 1993), both of which are necessary for plant infectivity.
How do you control yellow mosaics?
What is the most common plant virus?
1. TOBACCO MOSAIC VIRUS (TMV) Tobacco mosaic virus (TMV) has been voted as the most important plant virus in this poll of the plant virology community.
Which plant does TMV affect?
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.
