A news item and full length report have been posted regarding Iowa research this year examining the yield response of corn to fungicide applied at tasseling.

ISU Extension and the Corn Soybean Initiative partnered together to conduct research across the state to:

• evaluate the control of gray leaf spot (GLS), common rust, and stalk rot from a mid-season foliar fungicide application;
• assess the grain yield response of corn to foliar fungicide application;
• determine if foliar fungicide applications are profitable; and
• identify agronomic characteristics (such as hybrid and previous crop) that are important in determining when to spray fields.

The highlights of this research project can be found here:
