The role of several crop species on the survival of the Fusarium spp. was investigated. The root symptoms and plant weight of seven crop species were evaluated after inoculation with each of the three Fusarium spp. The number of colony-forming units of the Fusarium spp. from root tissues was also determined. Garlic was shown to be a symptomatic host for Foa, Fp and Fs; Fs was also pathogenic to onion. Root colonization of garlic, onion, maize, wheat, potato and sunflower suggested that they are reservoirs of Foa, Fp and Fs from asparagus and demonstrated the importance of crop rotation on the development of this asparagus disease.
