Plant diseases caused by Fusarium spp. will results in yield losses and are becoming more significant 
in Iran. In this study, infected plant samples suspected to Fusarium infection, plant debris and 
rhizosphere soil were collected from the most important crops that is, wheat, rice, corn, barley, potato, 
cucurbits from different provinces in Iran during 2002 to 2009. A total of 2,500 Fusarium isolates were 
obtained and classified into 30 species based on morphological characters. Fusarium sporotrichioides, 
F. chlamydosporum, F. graminearum and F. pseudograminearum were obtained only from tissue 
samples whereas F. scirpi, F. longipes and F. eumartii were from soils. Among the isolates, 41% were 
recovered from plant tissue, 36% from soil and 23% from plant debris samples. In cereals tissues, F. 
graminearum, F. pseudograminearum, F. sambucinum, F. culmorum, F. crookwellense, Fusarium 
proliferatum, F. verticillioides, F. fujikuroi and F. nygamai were predominant species. Fusarium spp. 
recovered from potato tissues were F. sambucinum, F. culmorum, F. crookwellense, F. trichothecioides, 
F. proliferatum, F. verticillioides, F. subglutinans and F. anthophilum whereas F. solani and F. 
oxysporum were predominant in cucurbits, sorghum, tomato, sugar beet and bean. To our knowledge 
this is the first comprehensive report on the identification of large number of Fusarium spp. in different 
crops from Iran.
