The invention prepared by un on account of our inventive steps is completely new. The composition B5 prepared from a bacterium namely B. subtilis strain B5 has the ability to provide plant growth promotion and control of soil/seed borne pathogens of potato, tegetables and ornamental crop plants. It releases an antibiotic metabolite which is fungicidal, supports immune system, biosynthesizes siderophores, tRNA binder, stimulatory, and decreases toxicity. Apart from fungicidal and bactericidal metabolite, the other metabolite, the other metabolite produced is a flavonoid, which is capable of removing dead cells, acts as a betoxifying agent, keeps cells healthy, increases metabolism and supports immunity. It has a killing effect against pathogenic species of Fusarium, pythium phytophthora Rhizoctonia, Solanacearum, the Alternaria in the form of cell lysis or antibiosis. Inhibits R. solanacearum, the cause of bacterial wilt of potato against whisch no chemical or a resistant variety is effective till date, by antibiosis, competitive inhibition and siderophore production. The effects of mechanisms involved to the reduction of diseases and the enhancement of crop yield reveal the fact that all the effects of interactions namely, cell lysis, antibiosis, competition and disease escape, are most obvious in case of attacks by siol-borne pathogens because they are able to operate in the rhizosphere area of the plant. The composition B5 is preparaed in an inexpensive substrate which allows maximum production of viable cells in shortest time with a shelf life of one year at room temperatures (15-37dgC)and gives best results when applied on seed or into soil, safe for persons handing it and non target pathogens with no side effects on biodiversity.
