Soybean Cyst Nematode Is Spreading — Here is How Farmers Can Fight Back

SCN Could Be Costing You 5–10% of Your Soybean Yield

Soybean cyst nematode (SCN) is one of the most damaging and difficult-to-detect pests in soybean production. Dr. Dylan Mangel, extension plant pathologist at the University of Nebraska–Lincoln, explains how SCN spreads, why it can cause significant yield loss without visible symptoms, and what farmers can do to manage it.

In this episode:

How soybean cyst nematode affects soybean yield

Why SCN can be difficult to identify in the field

When and how to soil test for SCN

How crop rotation and resistant varieties help manage populations

The connection between SCN and other soybean diseases

How SCN resistance is changing

Using the SCN Profit Checker to estimate yield and economic losses

Fall management steps farmers should take before next soybean crop

Learn why knowing your SCN populations—and keeping records over time—can be one of the most important steps toward protecting soybean yield.
