Pests in Gardens and Landscapes

Seasonal development and life cycle—Fusarium 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.
