fluorescent pseudomonads are important biocontrol agents showing capability to restrict or suppress phytopathogens, especially the fungal pathogens via production of some inhibitory metabolites and siderophores directly, and promote the plant growth through some different phytohormones. the objective of this research is to screen and introduce pseudomonas fluorescens utpf68 as a new biocontrol ...

abstract the role of fluorescent pseudomonads in biocontrol of take-all disease caused by gaeumannomyces graminis var.tritici (ggt) has been the subject of many researchs in the recent years. biofilm formation in fluorescent pseudomonads play an important role in biocontrol disease. for this purpose,130 strains of fluorescent pseudomonads isolated from wheat rhizosphere in different regions of ...

Although many Plant growth promoting rhizobacteria (PGPR) are used commercially, there is a need to explore more biocontrol agents combat various pathogens and sustain the productivity of crops. PGPRs inhabit rhizosphere region plant effective in managing pathogens. In this study, twenty-six PGPR isolates were screened in-vitro against fungal phytopathogens Bacteriological Laboratory, Departmen...

The ability of some soils to suppress plant disease has been well documented 1. An important example is the development of soils suppressive to Gaeumannomyces graminis var. tritici (Ggt), the causative agent of 'takeall' of wheat 2. Such natural examples of biological control have been attributed to the indigenous beneficial rhizosphere microflora (see Glossary), especially fluorescent pseudomo...

Many strains of Pseudomonas fluorescens show potential for biological control of phytopathogens especially root pathogens. In taxonomic terms, several of them are indeed P. fluorescens sensu stricto, while others belong in fact to neighbouring species of the 'P. fluorescens' complex or to ill-defined related species within the fluorescent Pseudomonas spp. These bacteria have become prominent mo...
