Role of Pseudomonas sp. in sustainable agriculture and disease management

Recently the growing population and climate change are the most severe challenge for both farmers and researchers from the last two decades. It is estimated that by 2050 the global population reaches to ~9 billion which demands ~60% extra food from the present, which creates extra pressure on the farmers to achieve the need of food. The farmers currently utilized huge amount of chemical fertilizers and pesticides to enhance the food production and disease management. These chemical fertilizers not only affect the texture and productivity of soil but also the health of plants, humans, and environment. From the last two decades, plant growth-promoting bacteria (PGPB) is one of the best choices as plant and soil inoculants to enhance the plant growth and disease management, due to their less impact on environment and eco-friendly nature. In this chapter, we focused on one of the most broadly used bacterial genus, Pseudomonas, which is present in the rhizosphere as well as within the tissue of the plants and used in sustainable agriculture for the enhancement of growth promotion and disease management.
