The purpose of this study is to evaluate the yield response and return on investment when applying fungicide at the VT growth stage on multiple hybrids.

2017 Southern Illinois Corn Fungicide Study - Hybrid Response

With minimal disease pressure present throughout the growing season, we did not observe any differences at the R5 growth stage. However, we still experienced an overall positive yield gain by spraying fungicide at the VT growth stage. With dry conditions throughout most of the growing season, conditions were not conducive for disease development. However, fungicides do aid in respiration, maintaining stalk integrity, and staygreen.
