Management Guidelines

  • Avoid planting in areas of high pressure to Goss's wilt.
  • Very good emergence and early vigor for all reduced tillage applications.
  • Best-adapted to sub 79-day maturity range environments, avoid moving south of target maturity range.
  • Good late-season health and plant integrity make it a good candidate for delayed harvest.
  • Strong roots and good tolerance to greensnap to support western adaptation.
