Abstract

In this study, a survey of root rot disease of wheat was carried out along the North Nest Coast (NWC) of Egypt under rainfed condi-tions. The survey revealed that high percentage of disease incidence was recorded.at Abo-Lahow followed by Abo-Atiah and Abo-Lowh. The lowest percentage of disease incidence was recorded at El-Hafian. The main pathogens causing wheat root-rot in NWC were Helmin‌thosporium sativum, Fusarium graminearum, F.moniliforme and Rhizocto‌nia solani. H.sativum was the most frequently isolated fungus, while the least frequent one was F.moniliforme. Pathogenicity tests proved that the most virulent fungus was F.graminearun followed by H.sativum and R.solani, while the least virulent one was F.moniliforme. Synergistic ef‌fect was noticed when the most virulent fungi were mixed and percent‌age of disease incidence was increased. Regarding the effect of soil textures on root-rot disease inci-dence, data obtained proved that the percentages of pre-post emer‌gence damping-off and disease rate were decreased by increasing the percentage of clay in soil to 75%, while , percentage of survival plants and wheat yield components were increased.
