Abstract

Indiscriminate use of chemicals as fertilizers and fungicide caused inconceivable detriment to the terrainand ecosystem including creatures and humans. To replace similar type of dangerous agrochemicals, naturalresult is handed by nature in the form of microorganisms having capacity to promote the plant growthwithout mainly harming the terrain. One of the natural approaches for the control of differentphytopathogenic agents is the use of biocontrol plant growth- promoting rhizobacteria (PGPR), which isable of suppressing or precluding the phytopathogen damage. The biocontrol PGPR belongs to the bacteriagenus Pseudomonas. Fluorescent pseudomonads are suitable for operation as biological control agents dueto their abundant population in natural soils and plant root system and their capability to use numerous plant exudates as nutrient. Fluorescent pseudomonads are known to have important traits in bacterialfitness similar as the capability to cleave to soil patches and to the rhizoplane, motility and prototrophy,conflation of antibiotics, and product of hydrolytic enzymes. In this review important characters, recentadvances and importance of P. fluorescens in reduction of pesticide pollution has been discussed.
