Updated 2025 Fungicide Efficacy Tables
Along with stocking our seed and prepping our planters, another way to prepare for the season ahead is to update our integrated pest management tools. Some of the most valuable resources are free! These include the fungicide efficacy tables published annually at Crop Protection Network. These tables are the product of dozens of site years of fungicide trials conducted by university pathologists across the country. These helpful charts include active ingredients, product names, rates, common diseases, harvest restrictions, and other notes. They are updated each year to reflect the newest data, including new products, label changes, and reduced efficacy due to pathogen resistance. If a product you are looking for does not appear in these documents, it may be due to insufficient university data to date. While we always include these tables in The Penn State Agronomy Guide for your convenience, we recommend downloading the latest versions to stay current.
