Don't Let White Mold Ruin Your Yield


Soybean farmers across the upper Midwest are seeing unwelcome signs of Sclerotinia Stem Rot, also known as white mold, in their fields. If the disease is not managed properly, white mold can spread into other nearby fields, infecting a significant number of plants and sending yields on a downward spiral. 

This year’s cool and wet spring has led to severe outbreaks throughout the Midwest. Visual symptoms in soybean fields include a fluffy, white growth and black sclerotia along the stem or bean pods.

To get ahead of the disease, consider the following steps:

  • Scout: White mold can cause the tops of soybean plants to start to turn yellow and brown near the R3 growth stage. This is often the first visual indicator that the disease is present in the field.
  • Treat: Foliar-applied fungicides can be used to manage the disease, or at least reduce the severity of it if treated in time. 
  • Rotate: Consider rotating to a non-host crop such as corn to control the disease in 2018.
  • Plan: Many Golden Harvest Soybean varieties have built-in tolerance to white mold. When deciding on your lineup for 2018, consider adding Golden Harvest Soybeans GH2041X brand and GH2230X brand. These varieties, which have proven performance in the upper Midwest, are designed to work in the toughest fields and are known for their outstanding tolerance to the disease. No variety is completely tolerant or resistant to this disease, but these Golden Harvest seeds set the standard.

As you make your seed decisions for next season, ask your Golden Harvest Seed Advisor about high-performing soybeans designed for tough fields that are susceptible to white mold. Contact your Golden Harvest Seed Advisor with questions or for additional agronomic insights.
