Abstract
A survey on the distribution, incidence and severity of date palm fungal diseases in the province of Oakahlia and Oamietta was carried out. Eight fungal diseases were recorded from these locations. False smut, black scorch, basal leaf rot, leaf spot and fruit rot diseases showed the highest disease index, whereas, inflorescence rot, root rot and bending head diseases were lower in their index. The spreading of fungal diseases among date cultivars showed that, Zagloul was the most susceptible cultivar by false leaf smut; black scorch and fruit rot diseases.
Belkas in Oakahlia province showed to be the highest infected area with false smut, black scorch; leaf spot and fruit rot diseases, with percentages of 75,37,34 and 28%, respectively. Faraskour region in Oamietta province recorded the highest infection percentage for Inflorescence rot (up to 18%) and root rot (up to 15%) diseases, while bending head disease recorded the highest infection percentage (up to 6%) in Oamietta region. Subsequently, false smut disease presented the most predominant disease in all regions of Oakahlia and Oamietta province.
A total of 17 genera and 24 species of various fungi were isolated from different affected parts of date trees. Botryodiplodia theobromae was the predominant isolated fungus followed by Thie/aviop < /em>sis paradoxa, Dip < /em>lodia p < /em>hoenicum and Fuserium oxysporum. Penicillium sp., and Melanospora zamiae were recorded at low percentage.
