and life cycle—Verticillium wilt
Both Fusarium and Verticillium form resistant structures that can survive in the soil in
the absence of a living host. These soil fungi are spread in soil water, on equipment, transplants, or
tubers. In the presence of a host plant, the resistant structures germinate and penetrate the plant's
roots either directly or through wounds. Once inside the root, the fungus grows until it reaches the water-conducting
cells, inside which it spreads upward through the plant, restricting water flow.
