Interpretive Summary: Soybean cyst nematode (SCN) is an important pest of soybean that reduces soybean yield world wide. This chapter discusses aspects of integrating management tactics for control of soybean cyst nematode with emphasis on the US. Topics discussed include damage thresholds, predictive sampling for nematodes, crop rotation, planting resistant varieties, planting blends, application of nematicides, tillage practices, and biological control. The chapter provides practical, realistic, and field developed information beneficial to stakeholders and scientists at present and the future potential for integration of biological control of SCN.

Technical Abstract: The cropping system in the USA that produces soybean every other year exerts severe pressure on the production system. Unless the system changes dramatically to produce soybean every third or fourth year, severe pressure will be continue and will reduce the likelihood of sustainable soybean production. In the foreseeable future, genetic resistance of soybean coupled with crop rotation will be the foundation of any management system for Heterodera glycines. Marker assisted selection will aid in selection and incorporation of specific genes and will increase the efficiency of developing resistant cultivars. However, any source of resistance may not be durable even with sound nematode management practices. Rotation of resistance genes (sources of resistance) has met with some success and may increase durability of sources of resistance. Integrating biological control in the production system with promising organisms such as Hirsutella rhossiliensis and Pasteuria nishizawae may lead to a truly sustainable system of soybean production in which H. glycines is no longer a yield limiting production factor.
