Regional strengths

MG 3 is the dominant maturity range across central Iowa, central Illinois, Indiana, and Ohio — Asgrow has a deep lineup tested annually in all four state programs. SCN resistance is non-negotiable here and standard PI88788 source is widely deployed; some varieties offer Peking source for fields with elevated SCN populations.

Regional weaknesses

Heavy reliance on PI88788 SCN resistance source has led to SCN populations adapting in many fields — request PI88788 vs. Peking source for the specific variety being considered. White mold can be severe in cool wet years on heavy soils, particularly in northern Iowa and northern Illinois.

Recommended for

  • full-season Corn Belt Core soybean acres
  • fields with documented SCN pressure

Not recommended for

  • fields with high white mold history without selecting specifically for tolerance
