Foot Rot symptoms on Sweetpotato
Foot Rot (fungus - Plenodomus destruens): Foot rot is a
relatively minor disease. On infected vines, the base of the
stem turns brown at the soil line and leaves nearest the crown
turn yellow and drop. It is most commonly observed from
mid-season to harvest. Individual plants may produce few
potatoes even though large vines develop during the season. The
potatoes that are produced develop a firm brown rot at the stem
end. Seldom is the entire root affected. Controls recommended
for black rot and scurf will also control this disease. If foot
rot is recognized to be a serious problem, then early harvest
will aid in reducing losses.
