Soybean sudden death syndrome
scouted Aug. 16, 2022
- Scientific Name
- Fusarium virguliforme
- Background
- Soybeans in Johnston county, variety AG52XFO, were scouted and sampled.
- Conclusion
- The issue was identified as Soybean Sudden Death Syndrome (SDS), caused by Fusarium virgulliforme. Afflicted plants suffer from flower and pod abortion, reduced seed size and vigor, and yield losses. Symptoms start at the roots, with necrosis and dieback, then the vascular tissue of the taproot turns brown and discolored, and later in the season, the leaves develop chlorotic spots that become necrotic. Crop rotations, resistant cultivars, and irrigation management, as well as seed treatments, are the best management practices for the mitigation of SDS. In North Carolina, losses by SDS often do not warrant the use of chemical controls.
