Primary infection usually occurs at the soil surface level. Sudden yellowing or wilting of plants is the first symptom. Light brown lesions, which quickly darken, enlarge until the hypocotyl or stem is girdled. Leaves turn brown, dry, and often cling to the dead stem. The tan to brown, spherical sclerotia resemble mustard seeds, are round to irregular in shape, and generally form around the infected plant.
