Phytophthora Root and Stem Rot on Papaya
Commonly affects: Carica papaya (Papaya)
The tree wilts and declines rapidly, sometimes with a water-soaked lesion visible at the base of the trunk, and can collapse entirely within weeks.
Potential Causes
- 1Phytophthora palmivora fungus thriving in waterlogged, poorly-draining soil
- 2Overwatering or planting in a low-lying area that collects standing water
- 3Heavy rain during warm weather providing ideal conditions for the pathogen
Solution Steps
- 1Plant papaya on a raised mound to ensure excellent drainage from the start
- 2Avoid overwatering, especially during warm, wet weather
- 3Remove and destroy severely affected trees, since recovery is unlikely once the trunk base is infected
- 4Apply a preventive fungicide drench in regions with a history of this disease
Prevention Tip
Papaya's soft trunk and root system make it especially vulnerable to Phytophthora â planting on a raised mound with excellent drainage is essential from day one.
