Sudden Death Syndrome (SDS) is a significant soybean disease caused by Fusarium virguliforme, primarily affecting growers in North America. It is especially prevalent in areas of monoculture soybean production, often exacerbated by the presence of soybean cyst nematode. Current mitigation strategies rely on resistant cultivars and seed-applied synthetic fungicides, primarily from the SDHI (Succinate Dehydrogenase Inhibitor) class. While these fungicides are effective, their long-term sustainability is uncertain due to resistance development, environmental persistence, potential non-target effects, and increasing regulatory scrutiny. 

There is a growing need for innovative, environmentally responsible seed treatment approaches to manage SDS in a more sustainable way. Effective alternatives that reduce reliance on conventional chemistries while meeting evolving market and regulatory expectations are critical for long-term disease management in North American soybean production.
