Management Guidelines

  • Agronomics and ear flex will support moderate to moderately high plant densities.
  • For optimum performance, position within 79- to 84-day maturity range environments.
  • Avoid placing in areas of high pressure to northern corn leaf blight and Goss's wilt.
  • In continuous corn, consider the use of a fungicide in high-disease situations.
  • Responds to good fertility program; maintain adequate nitrogen levels throughout season in high-yield environments.
  • Avoid late planting dates in less than 80-day maturity range environments.
