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.

The Aspergillus ear rot fungus produces aflatoxin, a dangerous toxin regulated in food and feed as it's harmful to people and livestock.

One management approach uses atoxigenic strains of fungus as biocontrol. Get the details in the NEWLY REVISED article at cropprotectionnetwork.org/publications...
