Management

  • Cleanliness and field sanitation including destruction of diseased tree topsand plant parts are foremost important in the management of the disease. Fallen infected nuts should be collected and burnt/destroyed.
  • Spraying with Bordeaux mixture 1.0% is recommended. Vegetable oils from ground nut, sesame, coconut or sunflower added to Bordeaux mixture before spraying also protect the palm from this disease.
  • Prophylactic spraying with Bordeaux mixture 1% once before the onset of south west monsoon and a second application 40-45 days later has been recommended with Metalaxyl MZ (0.2%).
  • Cover the fresh bunches after first spray with polythene bags to avoid fresh/further infection.
  • While spraying to the tree, the whole crown region should be covered.
