Abstract: The study was carried out to evaluate the root rot, wilting and the causal agents of date palm disease. The survey was conducted in nurseries, genepool I, genepool II, genepool III, genepool IV, genepool V, by-Pass I, II, III and# sucker seed garden. The diseased palm fronts were found to be overcrowded and overlapped on healthy palms which resulted to infections and adjoining on other heathy palms. Some of the date palms at chronic and acute stages were left unremoved which led to collapse and decapitation of the canopies. They became a reservoir for disease spread. Similarly, Pestalosia leaf spots were predominantly isolated from young seedlings. The dilution methods revealed that F. oxysporium f. sp. albedinis species were predominantly isolated from the bole, roots, fronts and soil. Genepool III NCRP 2B-08, planted in 1984 had the highest number of dead palms with 695 while the least were NCRP 2B-09 with 6 dead, planted in 1997 and by pass III planted in 2003 also with 5 dead. The sucker seed garden field planted in the year 2005 with the spacing of 8 x 8m did not record any dead palm. More time is needed to observe the field if they will develop similar symptoms of root rots and wilting of date palm observed in genepool I-V and by-pass I-11I. The male date palms were more susceptible with the isolation of F. oxysporium f. sp. albedenis species when compared with the female.
