Are your soybean fields showing yellow leaves this August? In this PCT Short, Jonah Johnson explains why soybeans can turn yellow and highlights an emerging disease growers need to watch for: Red Crown Rot.

Recently confirmed in Ohio, Red Crown Rot can mimic Sudden Death Syndrome (SDS), making it difficult to identify in the field. Jonah discusses key symptoms, including yellowing between leaf veins, leaf drop, red discoloration at the stem base, and the presence of small red structures on roots. Learn how this soilborne disease develops, why early detection matters, and what management practices can help reduce its impact.

If you suspect Red Crown Rot in your fields, sample testing is currently available through Ohio State University as researchers work to better understand the disease’s spread across Ohio.
