 Southern blight, caused by Sclerotium rolfsi, attacks the plant at or below ground level

by completely girdling the plant, preventing water and nutrient movement to support the upper

portion of the plant. As a result, the plant wilts and eventually dies (Florida Plant Disease

Control Guide, 1993, p. 395). Cultural practices used to control southern blight include plowing

under all crop debris and ceasing to plant in areas with a known history of disease. Another

alternative is to rotate with a grass crop in fields with high populations of the disease (Florida

Plant Disease Control Guide, 1993, p. 395). Treatment of soil with multipurpose fumigants

such as Vapam or methyl bromide containing varying concentrations of chloropicrin also aids

in the control of the disease, if disease is present at the time of treatment.
