Pests in Gardens and Landscapes

Seasonal development and life cycle—Verticillium wilt

The pathogen that causes Verticillium wilt is a soilborne fungus that infects roots and invades the water-conducting tissue of the plant. Verticillium dahliae attacks a wide range of broadleaf plants and can survive in the soil for many years without hosts. Verticillium levels are most likely to be high in fields where tomatoes, potatoes, or cauliflower have been grown.
