During the 2018 season a number of corn diseases were reported in Indiana. Do you know what you had in your fields? Did they impact yield? The usual suspects, grey leaf spot, northern corn leaf blight and stalk rots, were found throughout the state. Some minor diseases also occurred in areas –Physoderma brown spot and southern rust. In addition, there was an outbreak of the relatively new disease, Corn Tar Spot. The tar spot pathogen Phyllachora maydis was first identified in the United States in 2015 in Illinois and Indiana. An update of what is known so far about the biology and/or epidemiology of tar spot will be given.  

 

A review of corn disease identification, detection and monitoring will be presented. Then, disease specific management options such as host resistance, cultural practices and integration of fungicides will be discussed. Disease management in corn requires the integration of multiple strategies. The number of tools available for plant disease management continues to expand, but it is imperative we understand the Best Management Practices (BMPs) for each tool (new or old) in order to implement and incorporate them into current production practices to achieve effective and economical protection of yield.

Biography
Dr. Darcy Telenko is the new Field Crop Pathologist with the Department of Botany and Plant Pathology at Purdue University. She officially began her tenure as an assistant professor on August 1, 2018. Dr. Telenko’s research focuses on the biology and management of soil-borne and foliar pathogens of agronomic crops. She spent the last four years as an Extension Vegetable Specialist for the Cornell Vegetable Program at Cornell University in New York. Her responsibilities in that position were fresh market vegetable production, disease and weed management, soil health, and climate change resiliency. Darcy is a native of western New York and received her BS in Biological Sciences at Cornell University, MS in Plant and Soil Science at Southern Illinois University, and PhD in Plant Pathology and Crop Sciences at North Carolina State University. Prior to Cornell, Darcy’s post-doctoral research included studies in weed management of turf grass and agronomic crops at the University of Florida and disease management of agronomic crops at Virginia Tech.
