Fusarium oxysporum f. sp. vasinfectum W.C. Synder & H.N. Hans (FOV), first identified in 1892 in cotton fields in Alabama ( Atkinson, 1892), produces asexual macro- and micro-conidia as well as chlamydospores, stable overwintering structures. The fungus also survives in association with non-hosts, a particularly challenging trait since the ability to colonize roots of weeds and other crops allows FOV to persist in soil for years or decades ( Smith and Snyder, 1974). FOV also persists in seed, which can occur by contamination of cotton bolls in the field ( Bennett et al., 2008 and Elliot, 1923).
