These seedlings' coleoptiles have distinct brown lesions typical of seedling blight. Several fungi cause seedling blight, and these diseases are often worse with early planting. Although seedling diseases are common, they usually do not kill the seedlings outright. Seedling pathogens can cause other problems to later in the growing season. Cochliobolus can lead to common root rot and crown rot, Rhizoctonia to sharp eyespot, and Fusarium to dryland root rot.
