Survival can be several years, in the case of black rot of carrots ( Alternaria radicina [...] Typically, Alternaria causes spots on leaves, petals and stems. These spots can be distinguished by the dark and brown concentric rings that are caused by [...] seedlings. From the primary infection of leaves, this type of carrot disease can spread to the flowers (especially dangerous in crops for seed production)
