Citrus Melanose

Melanose is a saprophyte that completes its lifecycle on dead twigs. The disease severity is determined by the amount of inoculum on dead wood in the tree canopy and the duration of wetting periods following rainfall or overhead sprinkler irrigation. Around 18-24 hours of wetting are required for infection to occur and severe infection is favored by long periods of continuous wetting. Spores cause problems when there are significant amounts of dead wood on trees, on the ground or in piles of brush left in the grove.
