Noni Sunburn
noni stem lesion (canker)
Bleaching and bronzing of noni leaves due to exposure of shade-grown seedlings to full and direct sunlight.

Disorder: Sunburn.

Symptoms: The initial symptom of noni sunburn is bleaching of leaves within a few days after exposing shade-grown plants to full and direct sunlight. As the bleached tissues die, leaves become bronzed and brown.

Cause: Exposure of shade-grown noni seedlings to full and direct sunlight.

  1. Gradually acclimatize shade-grown seedlings to full sunlight.
Notes: Plants will adjust to full sunlight, but damage to the affected leaves is irreversible.
