Abstract: Plant pathology is that the scientific study of diseases in plants caused by pathogens (infectious organisms) and environmental conditions (physiological factors). Organisms that cause communicable disease embody fungi, bacteria, viruses, viroids. Plant pathology conjointly involves the study of infectious agent identification, illness etiology, illness cycles, economic impact, disease medical specialty, disease resistance; however plant diseases influence human and animals, pathosystem, genetic and management of disease. In the present article we have collected infected leaves of the different plants from the field and isolated fungus and treated with respective biocontrol agent. The result showed the Rhizobium inhibits the growth of Aspergillus spp. and Penicillium spp. (+), whereas on the Fusarium spp. (-) it does not show any effect. In case of Azatobacter, it inhibits the growth of Penicillium and fusarium spp. (+) whereas the Azatobacter (-) does not inhibits the growth of Aspergillus spp..B. subtilis inhibits the growth of the Fusarium spp. (+) but does not inhibits the growth of the Aspergillus and Penicillium (-).
