Southern corn leaf blight (SCLB) is a fungal disease of maize caused by the plant pathogen Bipolaris maydis (also known as Cochliobolus heterostrophus in its teleomorph state). The fungus is an Ascomycete and can use conidia or ascospores to infect. [ 1 ]
Cochliobolus miyabeanus is an important plant pathogen because it causes a common and widespread rice disease that causes high level of crop yield losses. It was a major cause of the Bengal famine of 1943, where the crop yield was dropped by 40% to 90% and the death of 2 million people was recorded. [3]
The fungal genus Cochliobolus includes 19 species, [1] it includes some plant pathogenic species such as Cochliobolus heterostrophus.A lot of former Cochliobolus species were transferred to either Curvularia or Bipolaris genera.

The taxonomy of Cochliobolus, Bipolaris and Curvularia is confusing due to the frequent name changes and no clear morphological demarcation between Bipolaris and Curvularia. A phylogenetic analysis of Cochliobolus, Bipolaris and Curvularia species was performed using rDNA markers (ITS1, 5.8S, ITS2) and a 600 bp fragment of gpd (glyceraldehyde-3 ...
Exserohilum was circumscribed by K. Leonard and Edna Suggs in 1974 to contain species formerly placed in Bipolaris with distinctly protruding hila. [2] Exsero which means stretch out and hilum which refers to the part of the organism. The truncate hila or hilum, protrudes from its distinct conidia which are ellipsoidal and distoseptate (forming ...
Curvularia can be distinguished from the species Bipolaris and Drechslera by the way (angle) walls (septae) divide the inner structure of their spores. The name of the teleomorphic state of the type species Curvularia lunata is Cochliobolus lunatus (Fam. Pleosporaceae, Ord. Pleosporales, Cla. Loculoascomycetes, Phy. Ascomycota).
