What Is Verticillium Wilt?

Verticillium wilt is a wilt disease affecting over 350 species of eudicot plants. It is caused by six species of Verticillium fungi: V. dahliae, V. albo-atrum, V. longisporum, V. nubilum, V. theobromae and V. tricorpus.

How do you stop verticillium wilt?

The best protection against verticillium wilt is growing plants with resistance or immunity to the disease. Verticillium-resistant tomato varieties carry a "V" on the plant tags or labels. Birch trees naturally resist the disease, and verticillium wilt doesn't affect conifers such as pine and spruce trees.

How do you get verticillium wilt?

Verticillium wilt is caused by a soil fungus called Verticillium dahliae. Another species, Verticillium albo-atrum, is less common. This fungus lives in the soil as small, darkened structures called microsclerotia. These microsclerotia may lie dormant in the soil for years.
