Overview

Leading hybrid for nearly every acre because of high yield potential, strong agronomics and stress tolerance.

  • Offers top-end yield potential in high-yield environments.
  • Strong agronomics include good stress tolerance and root strength.
  • Good ear flex supports variable plant densities and consistent yield performance.
  • Excellent grain drydown.

Management Guidelines

  • Semi-flex ear type supports variable plant densities; optimum performance achieved at moderate to moderate-high plant populations.
  • Good choice for continuous corn and corn/soybean rotations.
  • Do not plant under stressful emergence conditions such as extended periods of cold, wet soils.
  • Avoid areas with high Goss's wilt pressure.
