Alternaria rot

  • Causal Pathogen
    Alternaria alternate

The flesh of the apricot first becomes brown. The lesion is firm. The surface of the fruit is covered by dark green / black spore masses. The fungal growth initially appears dark, grey-black, with dark green colour to settle as decay progresses. Early infections on green apricots appear as red rings. As the fruit mature, the rings become sunken and brown, with signs of fungal matter settling thereafter. Alternaria rot is regarded as slow developing during storage.
