What is Sudden Death Syndrome of soybean?

Sudden Death Syndrome (SDS) of soybean is a fungal disease that develops in soybean and can cause severe yield losses. SDS symptoms suddenly appear usually after the flowering/reproductive growth stages through pod fill. The plants that look normal can in a short time turn yellow and drop leaves. This disease is caused by a soil inhabiting fungal pathogen called Fusarium virguliforme.
