Plant growth-promoting rhizobacteria and their applications and role in the management of soilborne diseases

초록

For a variety of reasons, more and more individuals are searching for alternatives to synthetic chemicals. In addition to other factors, synthetic chemicals used in disease prevention and control have the potential to have harmful effects on the environment. As a remedy for plant illnesses that are spread through the soil, plant growth-promoting rhizobacteria (PGPR) are discussed in this chapter. Pesticide-resistant gram-positive bacteriophages and biocontrol agents, as well as biopesticides, biofertilizers, and soil inoculants, are among the various concepts and nomenclatures examined in this study. Biological control agents, biopesticides, and soil inoculants are all investigated in this study. As a biocontrol agent, PGPR has its advantages and disadvantages. We also discuss the possible hazards of utilizing PGPR. Metabolites of PGPR are examined in this study, as is their role in the control of soilborne illnesses. It accomplishes this by presenting many case studies that act as examples. For the use of growth-promoting rhizobacteria to combat soilborne diseases, there are several more interesting case studies included in this collection. The biocontrol activities of PGPR have been extensively documented. Among these are the creation of antibiotics, siderophores, and enzymes that dissolve cell walls, as well as the development of systemic resistance, the efficacy of root colonization, and rhizosphere competency. © 2024 Elsevier Inc.
