AbstractIsolation of fungi associated with date palm leaf spot were carried out. Pathogenicity test revealed that Alternaria alternata (Fr.) keissler, Biopolaris australiensis (Ellis) Tsuda & ueyama, Cladosporium herbarum (pers.) Lind Gary, Fusarium oxyporum schelecht, F.solani (Mort.) sacc, Phoma leveillei Boerema and Bollen, Phoma glomerata (corda) wollenw and Thielaviopsis paradoxa(Deseynes) Hohn, gave typical symptoms of leaf spot on tested leaves. It was also found that disease severity was increased on outer leaves (older leaves) compared with younger leaves and on upper surface more that lower surface and on north side more than south side. Evaluation of five fungicide revealed that score (difenoconazole) inhibited completely the radial growth of tested fungi field experiment showed that score, Mancozab and Topas reduced the infection rate (r) for 0.032, 0.044 and 0.049 cm/day respectively compared to 0.098 cm/day for control treatment.
