How to Identify Southern Corn Leaf Blight
Prompt detection of SCLB is vital for effective management and control. SCLB is identifiable by elongated, tan to brown lesions on the leaves, usually 1 to 2 inches long and about 1/8 to 1/4 inch wide. These lesions, often rectangular and bordered by the leaf veins, may exhibit a slight yellow halo.
The disease can also manifest on the husks and ears of the corn. On the husks, the lesions resemble those on the leaves, while on the ears, they are more irregular and can lead to shriveled and darkened kernels.
