Soybean Cyst Nematode (SCN) and iron deficiency chlorosis have become dual thorns in Minnesota soybean growers’ side. SCN has been a plague on soybeans since the 1950s, reducing United States soybean producers’ yearly returns by an estimated $500 million.
Soybean iron deficiency chlorosis (IDC) can be found throughout Minnesota. Symptoms usually first appear on the youngest of the uppermost leaves. It is a complex plant disorder often associated with high pH soils.
Two University of Minnesota researchers are tackling the relationship between SCN and IDC – dubbed the Minnesota Challenge—head-on.
