Integrated Pest Management Options

Seed Treatment

Cool, wet spring conditions favour infection. Resistant varieties are not available. Minimize soil compaction and remove excess moisture through increased drainage. A small amount of tillage will help warm soil and improve surface drainage. Rotate with corn and wheat. Plant high quality seed when soil temperatures are above 13°C (55°F). Fungicide seed treatment recommended. Mounding or ridging soil at the base of the plants produces adventitious roots that can minimize losses.
