Frequent rainfall across the region has made timing fungicide applications in corn fields especially challenging. To help producers make informed decisions, we’ve created a quick reference guide outlining estimated rainfast periods for commonly used corn fungicides.
This guide summarizes drying times confirmed by manufacturer representatives or derived from EPA labels and technical fact sheets. Rainfast periods range from 1 to 4 hours, depending on the formulation. All values assume the crop canopy is dry at the time of application.
This chart is intended solely as an informational and educational resource. These values do not replace or supersede the official product label instructions. Always consult the current label before applying any pesticide.
