Southern corn leaf blight

Southern corn leaf blight (SCLB) is one of the most important corn leaf diseases caused by Bipolaris maydis  It affects the Zea mays species in warm, humidregions of the world. The yield loss occursdue to leaf surface lesion increase, compromising the photosynthetic area of plants.
There are two races of the pathogen. Race O normally attacks only leaves. Lesions are tan, somewhat rectangular in shape, and have reddish-brown margins. Race T attacks leaves, husks, stalks, leaf sheaths, shanks, ears, and cobs. Race T lesions are rectangular to elliptical (0.6cm to 1.3cm wide by 0.6cm to 2.0cm  long) with a reddish-brown border that may be surrounded by a chlorotic zone. Stalk and leaf infections initially appear as purple spots that develop tan-gray centers. Ear infections result in a gray-black lesion on the husk that extends into the kernels, appearing as a black felt-like mold. Seedlings from infected kernels are often blighted.
