Glossary of Terms

A Peking soybean is a variety with a specific genetic source of resistance to the Soybean Cyst Nematode (SCN), a damaging, yield-robbing pest. Discovered in 1957, this type of resistance is highly effective and increasingly used in rotation with common PI 88788 varieties to prevent nematode population buildup.

Iron Deficiency Chlorosis (IDC) is a plant disorder characterized by the yellowing of leaf tissue while the veins remain green, a condition known as interveinal chlorosis. It is primarily caused not by a lack of iron in the soil, but by the plant's inability to absorb the iron that is already present.

White mold in soybeans, caused by the fungus Sclerotinia sclerotiorum, is a significant disease often appearing in cool, wet, and high-yield environments. Symptoms include white, fluffy growth on stems, grayish-green foliage, and premature plant death. Management requires a combination of genetic resistance, wider row spacing, and timely fungicide application (R1-R3).
