Biological agriculture for the management of pests, diseases and plant health is a fast-growing segment of Agriculture, and biological solutions offer safe and sustainable alternatives to chemical pesticides. Plant growth-promoting rhizobacteria (PGPR) are root-colonising bacteria that exert beneficial traits on plant growth and development. In addition to plant growth promotion, PGPR are also used for controlling several plant pathogens, enhancement of nutrient up-take, and in rhizomediation. Therefore, they can act as biofertilisers, biostimulants and biofungicides, playing a range of important roles in sustainable agriculture.
