A serious fungal disease of maize (corn) plants, characterised by long, elliptical, greyish-green or tan lesions on the leaves.

The term can also refer to the fungal pathogen *Exserohilum turcicum* (syn. *Setosphaeria turcica*) that causes the disease. In a broader, metaphorical sense, it is sometimes used to refer to any widespread, destructive blight affecting foliage in northern regions.
