The risk of foliar disease pressure in some fields may be higher this year due to the current wet, humid weather on top of extra disease inoculums from the cool, wet years of 2008 and 2009. Experts at Pioneer Hi-Bred, a DuPont business, suggest scouting fields and then evaluating whether a foliar fungicide application offers benefits.

"Disease pressure varies greatly from field to field," said Brent Wilson, Pioneer technical services manager. "Foliar diseases — gray leaf spot, eye spot, northern leaf corn blight — are conducive to wet growing conditions.

"The window to see the greatest return from a fungicide application is rapidly closing as the corn crop and the disease cycle progresses," he said. "Fields with high disease pressure could still see a return on a fungicide investment."
