Alternaria black molds and stem cankers
Alternaria black molds and stem cankers are caused by fungal pathogens. Cankers appear on stems, leaves, and fruit, have dark brown to black color, and can lead to the death of a plant. Black molds appear as light to dark brown lesions on the surface of ripe fruits, that are later covered in a black layer.
Signs of damage:
Black mold is characterized by obvious lesions that appear on the surface of ripe fruit. Lesions are light to dark brown and vary from small flecks affecting only epidermal tissue to large, more or less circular, sunken lesions with decay extending into the carpel wall and often into the seed locule. During warm, humid weather the fungus may sporulate to form a black, velvetlike layer on the surface of the sunken lesions.
