Graph showing probability of recovering the cost of a fungicide at various application costs and corn prices.

RESEARCH: 400+ corn foliar fungicide data points from the U.S. & Ontario for applications at V6, VT & a 2-pass program at V6+VT.

RESULT: A single DMI+QoI fungicide at VT was the best chance for a positive ROI.
