Abstract The rose (Rosa gallica L.) is one of the most important ornamental plants grown in gardens, offices and homes. Roses are known worldwide for their fragrant showy blooms. El-Minia Governorate, Egypt, has a great cultivated area with roses, which used for several purposes in local markets and for exportation. Rose is subjected to attack by various disease pathogens which frequently induce severe losses in its plantations. Cutting rot of rose, in EL-Minia Governorate, constitutes a serious problem in most growing nurseries of rose and recent field observations have shown that the disease is widely spread causing destructive loses. 1- Rotted cuttings of rose (Rosa gallica L.) were observed in the nursery and greenhouse of Horticulture Department, Faculty of Agricultue, Minia University and in certain private nurseries in Minia and Giza Governorates. Infected cuttings were collected to use for isolate the associated pathogen (s) induced the disease. 2- Six isolates of different fungi belonging to five genera were isolated and identified as: Fusarium solani (three isolates), Fusarium sp. (one isolate), Rhizoctonia solani (two isolates) 3- Pathogenicity test revealed that isolates of Fusarium solani, Fusarium.sp. And Rhizoctonia solani induced basal rot of rose cuttings, while Aspergillus flavus, Mucor sp. and Rhizopus stolonifer were non pathogenic fungi for rose cuttings. |
