WHO CAUSES IT?
Alternaria citri is a phytopathogenic fungus that affects citrus trees, causing the disease known as citrus brown spot or alternariosis. This fungus produces spores (conidia) that spread through the air, infecting new plants. Alternaria citri can survive on infected plant debris as well as in soil. The fungus germinates under favorable conditions, invading plant tissues and causing lesions on leaves, stems and fruits.
