Downy Mildew

  • This disease is recognised by the yellow and white patches on the upper surface of older leaves. The underside of these are covered in a ¬†white to greyish cotton-like fungus.
  • This occurs more often after rain or heavy dew and disappears when sunny weather resumes.
  • Treatment is through a copper spray. Prepare the copper solution in the following way:
  • Fill a copper vessel with buttermilk and keep aside for 5 days. ¬†After this time period dilute 5 ml of this in 1 litre of water and spray the affected areas of the plant.
