List of files and visuals associated with this text.

SDS is a mid-to-late season soil associated conditions.
Symptoms include chlorotic leaves (Vis. 1) with large
necrotic areas that die and drop off, leaving the
petioles (Vis. 2). Pod drop may occur. Vascular tissue
in the stems and root deteriorates and turns gray-brown,
while the pith remains white. The disease is prevalent
during cool, wet seasons, with irrigated crops more
likely to be affected. For aid in control, use good
management practices and control soybean cyst nematode.
