Verticillium wilt—Verticillium dahliae
Verticillium wilt can affect all cucurbits. The first symptoms are wilting and yellowing of crown leaves,
which eventually dry up. Wilting gradually progresses out toward the runner tips; in severe cases, the
plant dies. Death may take weeks. A light brown vascular discoloration in roots is sometimes seen in cross
section. Aboveground vascular tissue is also discolored and can be seen by cutting through a node near
the base of the plant.
