Biotic threat in the form of insect pests is a major cause for yield loss in agricultural systems and an important factor affecting the structure and productivity of crop plant communities. However, bacteria antagonistic to plant pathogens and harmful insects are known to reduce plant contagion. These bacteria have been extensively studied in agricultural systems where they significantly contribute to soil suppressiveness, which is the natural potential of soils to inhibit plant pathogens. The genus Pseudomonas has been reported extensively not only for preventing infectious diseases but also promoting plant growth. Many Pseudomonas spp. have been reported for the presence of genes that responsible to construct and produce an array of imperative metabolites such as Indole Acetic Acid (IAA), 2-4 Di-Acetyl Phluoroglucinol (DAPG), HCN, Phenazines, Lipodepsipeptide, Pyrrolnitrin, Pyoverdin (Pvd) and Pyochelin etc. for such two fold and significant tasks.
