Capnodium salicinum Mont. 1849

Pathogenicity

ooty mould due to Capnodium salicinum is found on citrus trees following heavy infestation by citrus aphids (Aphis citricidus Kirk.) or scale insects. The fungus is not a pathogen on citrus leaves but is a superficial growth on the sugary secretions of the insects. Infected fruit has to be washed before marketing.
