Plants are usually predisposed to this fungus disease by certain practices such as the application of contact sucker control materials during hot weather. Irregular black lesions may extend from the soil surface to the top of the plant. A basal rotting of plants may occur, although roots are usually not affected . Stalks cut longitudinally exhibit appreciable pith and wood decay. In advanced stages, the pith may completely disappear resulting in a hollow stalk. Leaves of affected plants turn yellow, droop, and die. |

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. |
