| Abstract | High salinity of soils in arid and semi arid regions results in desertification and decreased crop yield. In such conditions plants become more vulnerable to diseases caused by pathogenic fungi. The aim of the present work was to select enhanced root colonizing bacteria for their ability to promote plant growth and control root rot of cotton caused by Fusarium oxysporum in salinated soil. The best five enhanced cotton root tip colonizer bacteria were selected from the rhizosphere of cotton grown in saline soil and were identified by the 16S rRNA gene sequence as Pseudomonas spp., Pseudomonas putida, P. chlororaphis, Pseudomonas mendocina and Pantoea agglomerans. They showed ability to promote plant growth and to control root rot of cotton caused by F. oxysporum. Infestation of the soil with F. oxysporum resulted in an increase of diseased plants up to 60%. Selected bacterial strains, reduced this proportion to as low as 19 % and also stimulated cotton growth. These results are promising for the application of selected environmentally safe biological control agents in protecting cotton against root rot disease in saline agricultural soils. |
