The reduction of yield, quality, and nutritional value of grain cereals by different fungal species is of great concern around the world. A comprehensive investigation was made on fungal mycobiota in rice from three provinces; Baghdad, Al-Najaf and Al-Qadisiyah of Iraq surveyed during the growing season 2014-2015. Fields were selected due to their location near the Euphrates and Tigris Rivers. Mycological analysis indicated that there were a difference rates in disease infection due to various fungal species. Predominant fungal species identified as Bipolaris spicifera , Curvularia lunata , Fusarium spp., Nigrospora oryzae , Exserohilum rostratum , Alternaria spp. and Thanatephorus cucumeris . Confirmation of the associated fungal species was further accomplished by analysis of their ribosomal DNA and internal transcribed spacer region sequences. The present study provides a detailed description of the associated fungal species, which may help in understanding the population dynamics and in developing effective control measures.
