Fusarium is a large, taxonomically complex genus. And had a confusing and unstable taxonomic. The morphological is a characters to separate species but morphological can be difficult to distinguish by inexperienced researcher. There fore, need to develop a reliable taxonomic system for this fungus because the problem faced with the array of different classification. Species diagnosis relies currently on morphological traits, support by the DNA sequence of several gene. Phylogenetic analysis is the methods of identification of species.
