Southern Stem Blight (Sclerotium rolfsii)
Gerard T. Berggren

The typical sign is a white cottony mold on the main stem at the soil surface. Small brown fruiting bodies (sclerotia) are associated with the mold. Infected plants are often killed.
To reduce losses, deep plowing to bury sclerotia, and rotation with non-host crops is suggested. Resistant cultivars are available, and should be planted in fields with a history of southern stem blight.
