Aspergillus crown rot. Causal Agent

Aspergillus niger






This disease can result in poor stands after planting and/or death of entire plants soon after emergence of seedlings. As plants develop woody stems and tap roots, this disease is less likely to occur. The succulent and elongating hypocotyl of seedlings is highly susceptible to this disease. Diseased tissues will appear sunken and tan to dark brown in color. Masses of black sooty spores of the fungus usually cover the decayed tissues.
