Hybrid corn is an economically important crop for the U.S. Corn is susceptible to several foliar fungal diseases, including northern leaf blight (NCLB), caused by Exserohilum turcicum. With susceptible hybrids yield losses can be devastating. This presentation targets growers, crop consultants and extension educators with a goal of improving their knowledge and understanding of this important foliar disease. The races that exist, their symptoms and the race by hybrid corn reaction. In addition the talk will review the conditions favorable for disease development, the disease cycle and management options available and the timing of these. This presentation is part of a set of presentations that will discuss foliar diseases of corn and fungicide recommendations for their management. The presentations are outputs of projects that have been funded by USDA-NIFA.
