Verticillium Wilt - Verticillium Wilt Disease

Symptoms:
Infected plants become yellowed and stunted, and leaves may fall off the lower portion of the infected stem.
In the early stages of disease, the yellowing often first appears as a V-shaped area at the leaf tip, and leaflets may roll upward along their length. As the disease progresses, the leaves may become bleached, white to pink in color and die.
Affected plants usually are scattered in a field.
Stems usually remain green while leaves die and frequently remain attached to the stem.
Leaf-to-leaf distance (node length) is shorter on infected than on healthy stems.
There are no external root symptoms, but an orange-brown ring may develop inside the root in the vascular system.
Plants are killed over a period of months
