Management Guidelines

  • Avoid planting in areas of high pressure to Goss's wilt.
  • For optimum performance, position within 79- to 84-day maturity range environments.
  • Avoid late planting dates in less than 80 maturity range environments.
  • Good stalks, roots and tolerance to greensnap may allow late-season harvest.
  • Best in rotation or when rotating to cornfields without corn rootworm pressure.
