WHO CAUSES IT?
Sooty mold is a fungal disease caused by several fungi of the genus Capnodium and other related genera. This fungus is not pathogenic itself, but develops as a black layer of sooty fungus on honeydew produced by sucking insects such as aphids, scale insects and whiteflies. Although sooty mold does not directly harm the plant, it can affect its health by blocking sunlight and reducing photosynthesis, leading to overall weakening.
SYMPTOMS
In citrus, sooty mold appears as a black, powdery coating that covers the leaves, shoots and fruits. This fungus develops on honeydew excreted by sucking insects that feed on plant sap, such as scale insects and aphids. Visible symptoms include leaves and fruits covered by a black, sticky coating, which can reduce the quality of the fruit and affect its marketability.

Recommendations
To prevent and control sooty mold in citrus, it is important to control the population of sucking insects, as they are the vectors of the fungus. Biological control methods can be used, such as the introduction of predatory insects, and specific insecticides can be applied when necessary. Additionally, it is important to keep the plant healthy through proper fertilization, regular pruning and controlled watering to avoid stress and reduce honeydew production.
