How can you control yellow mosaic virus?

How can you control yellow mosaic virus?

Control measures: — Infected plants should be removed. — Remove and destroy disease-affected leaves/plants from crop fields to avoid secondary spread. — Destroy host weeds. Intercrop with non host crops like sorghum, pearl millet and maize.

How can we control yellow mosaic virus in soybeans?

Seed treatment: Before sowing, treat the seed with Thiamethoxam 30 FS @ 10ml/kg seed or Imidacloprid 48 FS @ 1.25 ml/kg seed followed by seed inoculation. 3. Use of recommended seed rate, spacing and fertilizers: Higher seed rate results in more densely populated soybean crop which attracts more insects.

Which plant is resistant to yellow mosaic virus?

Plant materials The entry VMGG 012-005 is derived from Vigna radiata (VRM (Gg)1) x Vigna radiata (Pusa bold), developed for the purpose of Moderately resistance / tolerance to Mungbean yellow mosaic virus.

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 fast does mosaic virus spread?

Comments on the Disease Cucumber mosaic virus is spread from plant-to-plant by many species of aphids. Aphids only retain the ability to transmit these viruses for very short periods of time (minutes to a few hours). Thus, spread is often very rapid and local.

How do you control the yellow mosaic virus in Blackgram?

Washing the plants especially under surface of leaves by using low volume sprayer. Careful removal and destruction of infected plant portions during infection early stage. Placing of yellow sticky traps at 20/acre or light traps at 1 per acre to attract and kill the vector whiteflies.

How does Papaya control mosaic virus?

Control : As soon as the disease symptoms are observed dusting Sulphur (30 g/10 litres of water) or spraying Calixin 75 EC (5 ml/10 litres of water) at 15 days interval helps to control the disease.

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.

Does vegetative propagation helps in producing disease free plants?

Vegetatively propagated crops are often grown in tissue culture to obtain disease-free strains. 2. Altered planting/harvest dates: Planting and harvesting out of synchrony with pest populations can reduce pest damage.

What is mosaic virus in plants?

A mosaic virus is any virus that causes infected plant foliage to have a mottled appearance. Such viruses come from a variety of unrelated lineages and consequently there is no taxon that unites all mosaic viruses.
