  • Plant at medium-high to high plant densities for best results.
  • Performs well in conventional and no-till systems.
  • Good choice for continuous corn and corn/soybean rotations.
  • Widely adapted across soil types and environments with variable fertility and stress levels.
  • Good tolerance to northern corn leaf blight.
  • Susceptible to stalk rot; avoid delayed harvest when environmental conditions favor stalk rot development.
  • Keep north and avoid fields or areas at high risk for gray leaf spot.
