Tomato Mosaic Virus

Tomato Mosaic: Tomato mosaic virus (TMV)

  • The disease is characterized by light and day green mottling on the leaves often accompanied by wilting of young leaves in sunny days when plants first become infected.
  • The leaflets of affected leaves are usually distorted, puckered and smaller than normal. Sometimes the leaflets become indented resulting in “fern leaf” symptoms.
  • The affected plant appears stunted, pale green and spindly.
  • The virus is spread by contact with clothes, the hand of working labour, touching of infected plants with healthy ones, plant debris and implements.
  • Seeds from disease free healthy plants should be selected for sowing. Soaking of the seeds in a solution of Trisodium Phosphate (90 g/litre of water) a day before sowing helps to reduce the disease incidence.
  • The seeds should be thoroughly rinsed and dried in shade.
  • In the nursery, all the infected plants should be removed carefully and destroyed. Seedlings with infected with the viral disease should not be used for transplanting.
  • Crop rotation with crops other than tobacco, potato, chilli, capsicum, brinjal, etc. should be undertaken.
