Verticillium Wilt is a wilt disease that affects a massive range of woody and herbaceous plants causing them to wilt and lose leaves and potentially die.
Much like other wilt diseases, it hard to distinguish which disease it is. Verticillium Wilt stands out through the speed at which the plant wilts. In hot weather, the disease will cause the plant to wilt very suddenly and quickly. Another telling sign is dark marks in the wood of the plant. Usually, the marks are in the outermost growth ring of the plant.

Wilting of stems and leaves.
Visible black-brown rings when woody plants are cut.
