Management Guidelines

  • Best performance central and west where leaf diseases are less likely to occur.
  • Best performance when kept in maturity zone.
  • Avoid placing in environments with known high incidence of Goss's wilt.
  • Average tolerance to northern corn leaf blight (NCLB); may require fungicide in environments with known high NCLB pressure.
  • Good choice as a dual-purpose silage option for flex acres.
