Mycelial growth on corn ears typically begin at the base of the ear. In advanced stages of disease, this can result in a light-weight mummified ears attributed to the release of extracellular hydrolytic activities of acid protease, xylanases , and cellulases . [ 6 ]

The damage from MDMV can cause the halting of ear formation and development, ultimately leading to the production of barren ears and direct yield loss. [5] There can be losses of up to 42% on early-planted field corn. [6] If corn is planted late MDMV can cause 75% or more loss on inbred and hybrid varieties.
The spores are a sign of the disease and are used for dispersal of the disease to other corn and sorghum plants. When the ear of the corn is infected, it looks very small and tear-drop shaped and seems as though it does not have a cob inside at all. [5] The cob is replaced by white sori which are the structures that make and hold the spores of ...
As the disease progresses, the lesions grow together and create large areas of dead leaf tissue. The lesions found in Northern corn leaf blight are more acute if the leaves above the ear are infected during or soon after flowering of the plant. [4] In susceptible corn hybrids, lesions are also found on the husk of ears or leaf sheaths.
As one of the most devastating pathogens of sweet corn, C. carbonum causes Northern leaf spot and ear rot disease [1] while the asexual stage causes Helminthosporium corn leaf spot. [2] Cochliobolus carbonum is pathogenic to all organs of the corn plant including root, stalk, ear, kernel, and sheath. [ 3 ]
