Investigation of Genotypic and Phenotypic Characteristics of several Plant Pathogenic Fusarium Isolated on Different Hosts

In 2011-2013, to study of plant pathogen Fusarium species on different hosts, the samples from Yazd, Kerman and Mazandaran provinces were collected. This study was purposed for identification of plant pathogen Fusarium species on the basis of morphological and molecular characteristics and relationship between of species. The samples were detected to eight different species including: F. brachygibbosum, F. delphinoides, F. equiseti, F. globosum, F. graminearum, F. incarnatum, F. oxysporum and F. proliferatum. F. brachygibbosum as causal agent of oleander leaf spot, F. delphinoides as kidney weed root rot, F. equiseti as stem canker in castor bean, F. globosum as giant cane sheet blight, F. incarnatum as stem canker on redroot pigweed, F. oxysporum as aloe leaf rot and F. proliferatum as causal agents of sesame canker, cycas leaf blight and date palm vascular wilt, for first time have reported in Iran. F. delphinoides is a new species for the mycoflora of Iran.
