Reduced height corn and fungicide application research

Author: Clinton Hardy

Planning Unit: Daviess County CES

Major Program: Grains

Plan of Work: Agriculture Production, Management, and Environment

Outcome: Initial Outcome

The widespread adoption of fungicide application to growing corn has led to improved yields by better control of foliar diseases of corn.  This adoption has created a paradigm shift in the farmer approach to in season corn management and ever increasing opportunities related to application technique, fungicide options and now, reduced height corn varieties which increases the number of acres low-clearance ground equipment can navigate.  In order to provide research based data farmers can use in determining which application technique and corn height best meet their needs, the Daviess County agriculture agent connected extension corn pathologist, Dr. Kiersten Wise with a Daviess County farm business to host one of only two site locations in the United States that have ever been given the opportunity to grow reduced height corn in a un-biased University research protocol.  Upon conclusion of this commercial field scale research project, farmers and dealers will receive un-biased University based information pertaining to the yield prosects of two different reduced height corn varieties compared to a proven normal height corn.  Farmers will receive information related to the success and limitations of application by ground sprayer, aerial helicopter and aerial autonomous drone application techniques.  in addition to comparing yield, each application technique included a tracer product in which random leaves will be collected for genetic analysis to determine the percentage of leaf area covered by the different techniques.
