Fungal Disease (Pre & Post Harvest) – Speckle

Fungal Disease (Pre & Post Harvest) – Speckle:

Fungus Deightoniella torulosa causes 'Speckle disease' and the symptoms are minute reddish brown black spots surrounded by a green halo which develops at all stages of fruit maturity. The spots are 2 mm in diameter but may reach up to 4 mm as the fruit approaches harvesting. The fungus normally grows on the dead hanging leaves and spreads to fingers during rainy and windy weather.
