How can I manage the soybean cyst nematode?

Fig. 12. Guideline for SCN management based on SCN egg population density, and a soybean-nonhost annual rotation system, which is a common practice in Minnesota. For most fields, 5 years of SCN-resistant soybean and nonhost are needed to reduce the SCN egg population density to low enough (< 200 eggs/100 cm3 of soil) for an SCN-susceptible soybean. In some fields, 3 years of SCN-resistant soybean and nonhost (brown arrow) may be sufficient.

There is no way to eliminate SCN once it is present in a field. Instead, the goals of SCN management are to:

Currently, the most effective SCN management practices are:

You can take these steps, which provide the information necessary for making SCN management decisions:
