Summary:

Gray leaf spot is arguably the most important yield limiting disease of corn worldwide. It is a serious threat to production in the U.S. Corn Belt. The goal of this presentation is to help growers, crop consultants and extension educators to improve their knowledge and understanding of this important foliar disease. The talk will review characteristic symptoms of gray leaf spot, and discuss the disease cycle and conditions that favor infection by the pathogen, Cercospora zeae-maydis, and subsequent disease development. Furthermore, management options will be discussed with regards to the disease cycle. 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.
