Integrated Pest Management Options

Most severe when cool, wet conditons delay harvest. Some varieties are more susceptible than others. Fungicide seed treatments will improve the germination of low to moderately infected seed. Do not plant severely infected seed. Plant good quality seed with a germination rate of at least 80%-90%. Rotate with non-host crops such as corn and wheat, remove excess surface residue and harvest as early as possible.
