Indiscriminate use of chemicals as fertilizers and pesticide caused incredible harm to the environment and ecosystem including animals and humans. To replace such type of hazardous agrochemicals, biological solution is provided by nature in the form of microorganisms having capacity to promote the plant growth without substantially harming the environment. One of the biological approaches for the control of different phytopathogenic agents is the use of biocontrol plant growth-promoting rhizobacteria (PGPR), which is capable of suppressing or preventing the phytopathogen damage. The best characterized biocontrol PGPR belong to the bacteria genus Pseudomonas. Fluorescent pseudomonads are suitable for application as biological control agents due to their abundant population in natural soils and plant root system and their capability to utilize many plant exudates as nutrient. Fluorescent pseudomonads are known to have important traits in bacterial fitness such as the ability to adhere to soil particles and to the rhizoplane, motility and prototrophy, synthesis of antibiotics, and production of hydrolytic enzymes. Moreover, Pseudomonas also possesses plant growth-promoting traits such as nitrogen fixation, phosphate solubilization, iron chelation, and phytohormone production. Such multidimensional utility of fluorescent Pseudomonas makes them a bioagent of choice to be exploited in the field of agriculture.
