In this contemporary investigation fifty different plants used in traditional Indian medicine were examined against crown gall disease causing phytopathogen i.e. Agrobacterium tumefaciens using agar well diffusion method. The antimicrobial activities of fifty plant methanolic extracts demonstrated varyious inhibition effects on A. tumefaciens. Except the following six plants such as A. ilcifolius, A. officinalis, C. sativum, P. rubra, R. communis, and T. pumila were not exhibited the antimicrobial activity against A. tumefaciens. Among the selected fifty plants 88% of plants given remarkable bioactivity where as only the 12% of plants did not give antimicrobial activity against A. tumefaciens. https://biomedpharmajournal.org/vol2no1/biocide-potentialities-of-different-plant-methanolic-extracts-against-crown-gall-bacteria-viz-agrobacterium-tumefaciens/ Agrobacterium tumefaciens Crown gall disease Indian medicinal plants Soxhlet extraction
