The 2025 fungicide efficacy tables for foliar diseases of corn and soybean, and for soybean seedling diseases have been updated, and are now available through the Crop Protection Network website: https://cropprotectionnetwork.org/.

These tables are updated annually based on data provided by United States Extension plant pathologists, with efficacy determined through replicated research trials across a broad geographic area. Results from University of Kentucky research trials are included in the development of these national fungicide efficacy ratings.

The ratings in these guides reflect the efficacy of a fungicide against a given disease and are not rating yield response to a fungicide. It is an applicator’s legal responsibility to read and follow label directions. Updated tables include:

• Fungicide Efficacy for Control of Wheat Diseases
• Fungicide Efficacy for Control of Corn Diseases
• Fungicide Efficacy for Control of Soybean Seedling Diseases
• Fungicide Efficacy for Control of Soybean Foliar Diseases
