Abstract


The date palm occupies an important place in agriculture in the Saharan areas and contributes to the preservation of the fragile oasis ecosystem, threatened by desertification. Fusarium wilt of the date palm (phoenix dactylefra L.) known locally as "Bayoud" whose scientific name is Fusarium oxysporum f. sp. albedinis, poses a serious threat to the economy and society. As part of this work, we will try to better know the pathogen to better combat. The isolation of the fungus led us to obtain 05 isolates; their macroscopic characterization revealed two different morphotypes: the cottony morphotype and the ras mucous morphotype and their microscopic characterization the presence of hyaline and septate mycelium, with short monophialids on which microconidia are found, as well as the presence of macroconidia and chlamydospores.
