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.

560 million bushels gone. $2.9 billion lost.

These are the estimated losses caused by wheat diseases from 2018 to 2021. Read more in the new @planthealthprog.bsky.social publication at doi.org/10.1094/PHP-....
