The present study was conducted in Khartoum State in fifteen locations to investigate turf grass diseases. Turf grasses (lawns) are cultivated in private and public gardens andcourts are getting special importance in Khartoum State in recent years. However, blight disease- like symptoms have been observed in different gardens in Khartoum State. Therefore, the present research was conducted to study the blight disease of turf grass in Khartoum State. Theresults revealed the infection of turf grass fields surveyed with four fungi; namely, Fusarium nivale, Drechslera spicifera, Rizoctonia solani and Curvularia lunata. The identity of these fungi was confirmed by Blotter tests and culture in PDA. The association of these fungi with turf grass blight disease was confirmed by pathogenicity tests, which revealed identical symptoms of turf grass blight with those associated with the disease in the fields in private and public gardens and courts. The results of the present work are in agreement with the work reported by Lebean (1960), Smiley et al., (1992), and Nancy (1997), who showed the importance of applying Koch’s postulate to confirm the identification of the fungi causing blight diseases of Bermuda grasses.
