Fungicide resistance management has become a priority issue in the soybean industry  this year, especially as fungicide resistant strains of Cercospora sojina, the pathogen that causes Frogeye Leaf Spot, were confirmed in 10 states.

To help manage and avert fungicide resistance, the United Soybean Board awarded a research and education grant to sustain fungicide effectiveness and help growers and crop consultants manage fungicide resistance through outreach.

Dr. Carl Bradley, the principal investigator on the grant, teamed up with the nonprofit publisher Plant Management Network to produce the Soybean Fungicide Resistance Hub, a central destination for valuable information on soybean fungicide management.

This hub, located among the Plant Management Network’s suite of crop management resources, includes…

  • A ‘Featured Webcasts’ section, which highlights fully open-access videos on fungicide resistance management. Webcasts include…

Principles of Fungicide Resistance: Focusing on Soybean and Corn Production Carl Bradley, Extension Plant Pathologist, University of Illinois

Management of Frogeye Leaf Spot and Fungicide Resistance Heather M. Kelly, Assistant Professor, University of Tennessee

Fungicide Resistance: A Case Study on QoI Resistant Rhizoctonia solani Clayton A. Hollier, Professor and Extension/Research Plant Pathologist, Louisiana State University

  • A ‘Fungicide Resistance Tracking’ section which maps out the yearly distribution of fungicide-resistant plant diseases, such as Frogeye Leaf Spot and Rhizoctonia diseases.
  • A ‘Fungicide Resistance Resources’ section featuring useful extension information on fungicide resistance management of soybean crops.

The Soybean Fungicide Resistance Hub is a publication of the Plant Management Network.  To get the most out of the Plant Management Network’s full line of resources, please sign up for PMN’s free electronic newsletter, PMN Update.

Webcasts on a variety of other crops can be found in PMN’s Education Center.
