In this study, Neodeightoniaphoenicum isolated from palm trees infected with black scorch disease in tissue culture palm orchards in Basrah Governorate .The fungus identified morphologically and molecularly using the primers ITS1-ITS4. Molecular levels have been deposited in National Center for Biotechnology Information  (NCBI)GenBankwith (Accession No: MZ675601.1).The results of the morphological and molecularidentification were consistent. A pathogenicity test showed the ability of the fungus N. phoenicum to cause infection on the palm rachis inside the laboratory, and the infection was confirmed using Koch's postulates.
