Management Guidelines

  • Semi-flex ear type supports more moderate plant densities; avoid aggressive plant densities.
  • Avoid areas of known high incidence to Goss's wilt.
  • Foliar fungicide recommended in environments with a high incidence of northern corn leaf blight and eyespot.
  • Best performance when positioned in moderate to high yield environments; avoid sandy soils or environments conducive for moisture stress.
  • Best performance when positioned on rotated acres; avoid corn-on-corn acres.
  • Adapted to 86- to 91-day maturity range environments, and best-adapted to central and western growing regions.
