Yellow Mosaic Disease in Okra/Bhindi:-

  • This is the most important and destructive viral disease in bhindi.
  • The disease infects at all the stages of crop growth and severely reduces growth and yield.
  • The disease is transmitted by whitefly.
  • The characteristic symptoms of the disease are a homogenous interwoven network of yellow veins enclosing islands of green tissues.
  • Initially, infected leaves exhibit only yellow coloured veins but in the later stages, the entire leaf turns completely yellow.
  • The fruits of the infected plants exhibit pale yellow colour, deformed, small and tough in texture.

Control-

  • Remove and destroy disease-affected leaves/plants from crop fields to avoid secondary spread.
  • Parbhani Kranti, Janardhan, Haritha, Arka Anamika and Arka Abhay can tolerate yellow vein mosaic.
  • Do not use high fertilizer during plant growth.
  • Do not roted okra with other hosts of virus.
  • If possible, choose early planting to the controlling of yellow mosaic virus disease.
  • Keep sanitation while using any tools that are using in crop.
