The purpose of this study is to evaluate Preemptor SC at four different growth stages to determine the ideal timing of fungicide applications to impact yield and overall return on investment.

2017 Central Illinois Corn Fungicide Timing Study

Based on our past PFR data, we have come to recognize that a fungicide application made at the VT growth stage provided the highest return on investment (ROI). This year, we decided to delve deeper into this study and look at applications made during the early reproductive stages in an effort to find the ideal timing. Given the abnormally dry summer we experienced, a lower level of disease pressure was observed. This data concluded that a fungicide application at the VT growth stage remains the highest ROI, even when testing later applications.
