Soybean cyst nematode, Heterodera glycines, was first identified in Ohio on soybean in 1987 and has now been found in 68 counties in Ohio. Soybean cyst nematode (SCN) damages soybeans by feeding on plant roots, robbing the plants of nutrients, and providing wound sites for root rotting fungi to enter. The severity of symptoms and yield losses are dependent on several factors including: the number of nematodes present in the field at planting, the soybean variety, tillage practices, soil texture, fertility, pH, and environmental conditions during the growing season. Once SCN has become established in a field, it rarely is eradicated. SCN is the leading cause of soybean yield loss in North America and now occurs in all major soybean production areas worldwide.
