Fusarium wilt group is a vascular fungus caused by a xylem pathogen called F. oxysporum. However, in its current concept F. oxysporum is a species complex consisting of numerous cryptic species. Several hundred plant species are susceptible, including economically important food crops such as sweet potatoes, tomatoes, legumes, melons, and bananas (in which the infection is known as Panama disease). Many plant pathogenic strains are known based on host plant specificity and the large number of plant species attacked.

One of these strains, Fusarium oxysporum f.sp. Collectively, F. oxysporum strains can cause wilt or root, bulb or foot rot in a wide variety of plant species, among which are several economically important crops (Gordon & Martyn, 1997).Individual strains of F. oxysporum, however, usually infect only one or a few host species. Severe external stem damage. Fusarium oxysporum, bir askomiçet mantarıdır ve Nectriaceae familyasının parçasıdır. Yerli topraklardaki baskın rolleri zararsız veya hatta faydalı bitki endofitleri veya toprak saprofitleri olabilse de, F. oxysporum kompleksi içindeki birçok suş, özellikle tarımsal ortamlarda bitkiler için patojeniktir.
