Protect Your Soybean Profits: Manage Soybean Cyst Nematode


The soybean cyst nematode (SCN) is the most serious soybean pest in the United States. Even though soybeans can be produced profitably in SCN-infested fields, the nematode causes millions of dollars worth of soybean yield losses each year. Why ? Because SCN causes no specific symptoms and its effects are often not dramatic. Thus, many farmers do not know that their fields are infested with SCN until a severe problem develops. Meanwhile, up to 30% yield losses can occur without obvious symptoms.

This publication was developed with you, the soybean farmer, in mind. Included in these pages are recommendations and information based on decades of research on soybean management in SCN-infested fields. This research has shown that soybeans can often be produced profitably in spite of SCN. The burden is on you to determine whether you have SCN infestations, and to tailor a management strategy for your farm. We hope the following sections will be useful to you:



This publication was based on “Soybean Cyst Nematode”, edited by Dr. William F. Moore (Mississippi State University). This revision was initiated by the Nematology Committee of the Southern Soybean Disease Workers. Funding for publication was provided by the United Soybean Board through the National Soybean Checkoff.
