Symptoms
- The cankers appear either on the main trunk, jorquettes or fan branches.
- The earliest symptom is the appearance of a greyish brown water soaked lesion on the outer bark.
- A reddish brown liquid oozes out from these lesions, which later dries up to form rusty deposits.
- The tissues beneath the outer lesion show reddish brown discoloration due to rotting.
Management
- It can be controlled in the initial stages by the excision of diseased bark followed by wound dressing with Bordeaux mixture or copper oxychloride paste.
- Wilted branches should be cut and removed.
