southern blight |
Sclerotium rolfsii |
With this fungal disease, leaves of infected plants rapidly turn yellow, wilt, and die. The dried, brown leaves hang down the dying stalk. The root system remains healthy prior to the death of the plant. Infected plants are usually scattered singly through the field or occur in small groups. Symptoms may be confused with those of black shank. During warm, moist weather, the fungus produces a white cottony growth from the discolored stalk lesions. Discing of the pith similar to black shank may occur, but it is much lighter in color and not as well-organized. Infected stalks easily break at the stalk lesion. |

The fungus produces small, round structures (sclerotia) on the surface of the stalk lesion. These are white at first, turning brown with maturity, and resemble mustard seed. |
