Each year the Wisconsin Field Crops Pathology Program conducts a wide array of fungicide and disease management tests on alfalfa, corn, soybeans, and wheat. These tests help inform researchers, practitioners, and farmers about the efficacy of certain fungicide products on specific diseases and how to pair them with other disease management strategies. We hope you find this report useful in making decisions for the 2023 field season.
The 2022 Wisconsin Field Crops Fungicide Test and Disease Management Summary is available by clicking here (https://badgercropdoc.com/2023/01/20/2022-wisconsin-fungicide-test-and-disease-management-summary-now-available/). These tests are by no means an exhaustive evaluation of all products available, but can be used to understand the general performance of a particular fungicide in a particular environment.
