Unraveling Citrus Black Sooty Mold

Identifying Black Sooty Mold

Black sooty mold on Citrus plants appears as a dark, velvety coating on the leaves, stems, or fruits. This mold isn’t a direct pathogen but develops as a secondary issue caused by honeydew secreted by sap-feeding insects like aphids, scale insects, or whiteflies.

Causes and Remedies for Black Sooty Mold

  1. Pest Infestations: Control and manage sap-sucking insects to curb honeydew production, thereby reducing the mold’s growth. Implement natural predators, horticultural oils, or insecticidal soaps to mitigate infestations.
  2. Honeydew Removal: Regularly wash the affected areas to eliminate honeydew, which discourages the growth of black sooty mold. A gentle wash with water and mild soap aids in removing the sticky residue.
  3. Pruning and Cleaning: Trim heavily infested sections and dispose of affected leaves or branches. Cleaning the plant periodically prevents the spread of both pests and mold.
  4. Plant Health Maintenance: Ensure adequate nutrition, proper watering, and optimal sunlight for the Citrus plants to bolster their resilience against pests and mold.
