The risk of this disease remains moderate to high east of the Missouri River and south of I-90. 

Next 2-week risk interpretation 

During the next two weeks weather conditions are favorable or moderately favorable for FLS in the southcentral parts of the Corn Belt.  Scout susceptible cultivars in at-risk areas, and if fresh disease lesions are observed on the upper leaves, consider a fungicide treatment if the plants have not reached R5 growth stage.
