Variety performance review
Asgrow MG 3.x Soybean in the Corn Belt Core.
- Good
- Bayer Crop Science (Asgrow)
- Maturity Group 3.0–3.9
- GMO
Trait package: Roundup Ready 2 Xtend
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.
