Employments of excess of chemical pesticides in the management of plant disease became major problem to main table agronomics. PGPRs is usually known for plant protection as well as for enhancing crop productivity. The implementation of PGPR can reduce the requirement of pesticides and chemical fertilizers which is very important for sustainable agriculture. This is proved by the researchers PGPRs enhancing the crop yield via direct and indirect mechanism of plants. Pseudomonas fluorescnes is an important PGPR which have great importance in systemic resistance ,plant growth promotion, and biotic management of plant disease and plant growth promotion. Farmers applied large amount of chemical pesticides and food production. PGPR are most important agents in the reduction of disease and increment of growth and yield of plants. Seven strains of Pseudomonas fluorescnes were separated from the soil of pigeon pea field. Pseudomonas fluorescens have significant importance in the increment of plant health and growth. The current study aim to isolated and identify the Pseudomonas fluorescens from the soil their role in the control of wilt disease of pigeon pea. PGPR suppresses plant disease by production of IAA, sulphur, phosphorus, and siderophores. Pseudomonas fluorescens significantly control the plant pathogens. Pseudomonas fluorescens produced the solubilized phosphorus, potassium and fix the atmospheric nitrogen. Pseudomonas fluorescens not only protected plant from pathogens but also enhanced the soil fertility. PGPRs are the important microorganism produced the molecules which enhanced production plant hormone, growth and development. Copyright@ International Science Community Association
