This work was carried out in Diyala Province, North of Baghdad, Iraq during 2016-2017 to isolation and identification the fungi caused Inflorescence rot on data palm and try to combat the disease by using sodium chloride salt . 32 infected samples were collected from 8 varieties of data palm which has been isolated 60 isolates of fungi belong to 6 genus and species of fungi which were Mauginiella scattae, Fusarum proliferum, Penicillum chrysogenum, Rhizopus spp., Mucor spp. and Aspergillus niger, the number of isolates for each one were (20,12,10,6,6,6) respectively. M. scattae showed highest percentage of frequency and occurrence that (33.33, 65.63) %, while F. proliferum recorded the lowest percentage of frequency and occurrence which were (6.66 , 18.75)%. Treatment with the sodium chloride salt gave significant reduction in Inflorescence rot on all data palm varieties. Disease incidence and percentage of Infection, which were 0% in all data palm varieties excepting khistawi variety which recorded (22.22, 33.33)% respectively for  while control treatment  recorded (100, 100)% respectively for Disease incidence and percentage of Infection. This confirms the possibility of using sodium chloride salt as a substitute for chemical fungicides.
