Mosaic Virus

Ridge Gourd

Name: Mosaic Virus

Scientific Name: Cucumber mosaic virus (CMV)

Crop: Ridge Gourd

Description:

  • Warm weather is favourable for the spread of the mosaic virus. It is transmitted by aphids and other vectors.

Damage Symptoms:

  • Light and dark green mottled patches appear on the leaves, and the leaf shape becomes distorted.
  • Plant height is stunted, and fruits are deformed in shape and size with poor taste and quality.
  • Reduced flowering leads to lower fruit setting, causing yield loss.
  • In severe cases, the fruit skin becomes rough and bumpy, making it unsuitable for the market.

Preventive Measures:

  • Install sticky traps in the field.
  • Plant four rows of barrier crops around the field.

Control Measures:

  • Apply Imidacloprid or Thiamethoxam.
