Kansas State Plant Pathologist Erick De DeWolf has put out, in my opinion, the most accurate winter wheat fungicide efficacy ratings. You can review it here. In it, he summarizes performance ratings and also provides insight we can utilize as we make plans for fungicide applications on our wheat this year.
In addition to these ratings, I wanted to share with you a few thoughts I had looking back on the 2016 season.
Understanding varietal differences in resistance helps target your field scouting effort.
Top: Beck's dealer Paul Coke shows a leaf with initial stripe rust infection diagnosed April 13, 2016 in Pike County, MO.
Bottom: Wheat field near Frankford, MO on May 2, 2016 showing the difference in severity of Stripe Rust infection between a field area that received a preventative fungicide and one where the spray boom skipped the fungicide application.
Managing your fungicide plan now is very important for achieving high-yielding wheat. The bottom line is, disease or no disease, fungicide applications are crucial to increasing your return on investment. Your wheat yield potential at the time of application is a key factor in determining whether or not to apply a fungicide. If you have any questions please reach out to myself, your seed advisor or local dealer.
