Areas with no-till farming practices are at a much higher risk of infection than those that till consistently. Tillage of residue into the soil will decrease the survival rate of the fungus and thus reduce further risk of infection. It is best to avoid planting extremely early, especially in wet fields.
Fields that have high fertility or high soil organic matter are at risk for stem canker infection. Maintain a well-balanced soil mixture to reduce risk of impact. Please contact your local plant pathologist to learn what is most effective in your area and how to use it best. Always read and follow all label instructions.
