Summary

​Annual U.S. soybean yield losses caused by SCN are estimated to be more than 30 million bushels and greater than that caused by any other infectious disease. An elementary knowledge of nematology biology and host-parasite relationships is essential for proper identification and management of SCN problem fields. Because symptoms are often difficult to observe under field conditions, a laboratory analysis is frequently necessary to confirm SCN in a specific field. Some SCN populations are more aggressive than others and require a SCN Type test for use in selection of an appropriate SCN resistant variety. Continual use of SCN resistant varieties from a single source of resistance can result in development of highly aggressive SCN populations. Chemical, biological and plant health regulator seed treatments have been developed for use with SCN resistant varieties.
