Soybean cyst nematode (SCN), originally identified in North Carolina back in the 1950s, has now spread to the majority of soybean growing regions as of 2023.

Why should farmers be vigilant about this pest? While we’ve relied on the genetic approach of PI 88788 resistance for over 30 years to combat SCN, resistance is emerging, and though we haven’t reached a full-blown crisis, we’re heading in that direction.

Dr. Mandy Bish of University of Missouri Extension urges farmers to take a proactive stance in managing SCN as there are limited tools available for control.
