Foliar fungicide use on corn in Illinois has increased drastically beginning in 2007. In an effort to better understand the factors considered in corn fungicide application decisions, attendees of a series of meetings in Illinois were surveyed. Results indicate that disease pressure was the most important factor considered by the greatest percentage of survey respondents (38%). Factors not related to disease or disease risk were considered the most important factor for 23% of the respondents. These results indicate that additional Extension programming is needed to teach the importance of considering disease and disease risk when making a fungicide decision.
