Fusarium wilt is a common vascular wilt fungal disease, exhibiting symptoms similar to Verticillium wilt. This disease has been investigated extensively since the early years of this century. The pathogen that causes Fusarium wilt is Fusarium oxysporum (F. oxysporum). [1] The species is further divided into formae speciales based on host plant.
The symptoms are similar to most wilts with a few specifics to Verticillium. Wilt itself is the most common symptom, with wilting of the stem and leaves occurring due to the blockage of the xylem vascular tissues and therefore reduced water and nutrient flow.

Verticillium wilt affects over 300 species of eudicot plants caused by one of two species of Verticillium fungus, V. dahliae and V. albo-atrum. Many economically important plants are susceptible including cotton, tomatoes, potatoes, eggplants, peppers and ornamentals, as well as others in natural vegetation communities. [citation needed]
Fusarium (/ f j u ˈ z ɛər i əm /; Audio: ⓘ) is a large genus of filamentous fungi, part of a group often referred to as hyphomycetes, widely distributed in soil and associated with plants. Most species are harmless saprobes , and are relatively abundant members of the soil microbial community.
The disease that this pathogen causes is fusarium yellows or fusarium wilt. [2] Fusarium oxysporum f.sp. betae is a type of fungus whose spores survive in the soil. [2] The symptoms of Fusarium oxysporum f.sp. betae are yellowing between the large veins, chlorosis, wilting, and necrosis of leaves. [2]

Gibberella xylarioides (Fusarium xylarioides) is a species of fungus in the family Nectriaceae. It is the causative agent of coffee wilt disease (CWD). The disease caused a severe problem in several countries in West and East Africa during the 1940s and 1950s. [1] CWD was first seen in Coffea liberica. [2]
