Early-Season Corn Disease: Northern Corn Leaf Blight
Joshua Putman, Field Crops and Forage Specialist
Southwest New York Dairy, Livestock and Field Crops Program

In 2019, northern corn leaf blight (NCLB) appeared throughout the Southwest New York region. In general, NCLB is more of an issue in fields with a history of continuous corn production however, this year, the environment has been conducive for the infection to occur in first year corn fields as well. Environmental conditions of 65-85F, sporadic rain events, and humidity can result in an NCLB infection. Early NCLB symptoms appear as long, narrow, tan lesions that form on the leaf surface of a corn plant. As the disease progresses, the lesions become longer, more oblong, or "cigar-shaped" and can appear grayish in color. These lesions can range from 1-8 inches long with multiple lesions forming dense, irregular areas of dead tissue on the corn leaves. Cornell University Field Crops Plant Pathologist, Dr. Gary Bergstrom, recommends we scout our fields now for early disease detection.
