Sclero-cast: A Soybean White Mold Prediction Model
**This tool is for guidance only and should be used with other sources of information and professional advice when determining risk of white mold development. We encourage you to read the model how-to guide which can be downloaded by clicking here**
Risk of apothecial presence and subsequent white mold development is currently highest for soybean fields in the west-central to northwest portions of Wisconsin. Risk is further elevated in fields planted to 15″ row-spacing and/or irrigated. While many soybean fields are likely not flowering yet, these risk models should be monitored closely to assist in making in-season fungicide application decisions during the soybean bloom period. For more information on white mold and white mold management, see this previous post.
