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 generally low for most of Wisconsin today. A few isolated pockets of moderate or higher risk are located around Shawano Co. and north of Barron Co. Soybeans in this area are likely not at the susceptible growth stage. A high-risk pocket is also present in the southeast in western Waukesha Co. Growers near this pocket should monitor the soybean crop for closing canopy and flowering growth stages that may lead to increased risk of white mold.
