Crown-gall disease; as one of important bacterial disease in the nurseries, causes significant economic damage. This disease is characterized by a tumor-like growth or gall on the infected plant which reduces the growth and weakens the infected plants. The causative agents of this disease are belonged to Agrobacterium species. In the Spring and summer of 2019 symptoms of gall disease observed on the stems and roots of Weeping fig in some regions of Kerman province. Ten isolates resembling of Agrobacterium were isolated by standard bacteriological methods and identified by pathogenic, biochemical and molecular tests. Based on phenotypic features and using of specific primers in molecular assay, belonging of isolations to the species Agrobacterium and especially the genomic collection of A.tumefaciens was proved. To our knowledge, this is the first report of stem and crown gall disease of Weeping fig caused by A. tumefaciens in Kerman Province on Iran.
