Cercospora Carotae
Pathogen:
Cercosporosis
WHO CAUSES IT?
Cercospora carotae is a phytopathogenic fungus responsible for carrot pox and leaf spot. This pathogen produces conidia that are dispersed through air and water, especially during high humidity conditions. Conidia germinate on the surface of the leaves and penetrate plant tissues through stomata or wounds. Once inside the plant, the fungus develops mycelium that spreads between the cells, feeding on the plant's nutrients and causing the death of infected cells. Cercospora carotae can survive on infected plant remains and in soil for long periods. Spores can be carried by wind, irrigation water, and contaminated growing tools. Initial infection usually occurs in older leaves and progresses to younger ones. Spores are produced in abundance on foliar lesions, facilitating continued spread of the fungus during the growing season.
