Northern corn leaf blight (NCLB) is caused by the fungus Exserohilum turcicum. This disease can be found in corn growing areas with humid climates and may cause significant yield losses when moderate temperatures (65 to 85° F) and extended periods of dew prevail. Yield losses of more than 30% have been reported when lesions are present on upper leaves at silking. In addition to grain losses, infected plants may have reduced forage value and be predisposed to stalk rots.
