Verticillium alfalfae doesn't survive well without a living host though it can persist in dry hay up to 3 years. Verticillium dahliae does produce micro-sclerotia that allow this species to survive many years in the absence of a host. Irrigated fields are the prevalent sites of the disease in the Pacific Northwest.

Verticillium wilt of alfalfa is a warm-season disease and can be serious in susceptible varieties. Yields have been reduced by 50% in the second year of production. This disease has been found in alfalfa growing areas in the Mojave Desert and Riverside and San Bernardino counties.
Verticillium wilt begins as a mild, local infection, which over a few years will grow in strength as more virile strains of the fungus develop. If left unchecked the disease will become so widespread that the crop will need to be replaced with resistant varieties, or a new crop will need to be planted healthtechdays.com: Sordariomycetes.
