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 ]
Northern corn leaf blight (NCLB) or Turcicum leaf blight (TLB) is a foliar disease of corn caused by Exserohilum turcicum, the anamorph of the ascomycete Setosphaeria turcica. With its characteristic cigar-shaped lesions, this disease can cause significant yield loss in susceptible corn hybrids.
The purpose of disease management is to prevent the amount of secondary disease cycles as well as to protect leaf area from damage prior to grain formation. Corn grey leaf spot is an important disease of corn production in the United States, economically significant throughout the Midwest and Mid-Atlantic regions.

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 ]
[2] Corn anthracnose leaf blight is the most common stalk disease in maize and occurs most frequently in reduced-till or no-till fields. [3] Anthracnose stalk rot. Symptoms can vary depending on which part of the growing season the corn is in. [4] Early in the growing season, the main symptom is foliar leaf blight.
Phyllachora maydis is a plant pathogen causing ascomycete diseases in maize/corn, and is more commonly referred to as tar spot. [1] [2] Identified by the distinctive development of stroma, this pathogen in itself is of little economic importance in the production of corn.
