Pseudomoas Fluorescens

Psedodomonas fluorescens (2 x 10” cfu/g min.) is a rhizosphere bacteria which protects plant roots against parasitic fungi such as Fusarium or Pythium as well as certain phytophagaous nematodes such as Meloidogynesps.Fungi such as alternaria cajani and curvularia lunata grow on plant surfaces causing disease and death of plants. Plant treatment with Pseudomonas fluorescens can limit these fungi from growing and prospering. It is non-specific in its ability to protect plants and, once established, it works against several different pathogens while inducing systemic resistance in the host plant. Production of secondary metabolites plays an important role in plant disease suppression and PF produces substances like 2,4-diacetylphloroglucinol, which is responsible for the anti-phytopathegenic and the biocontrol properties of PF.PF aggressively colonises the roots of the crop and suppresses disease by inhibiting phytopathogens in the soil or on the roots by competition and/or antagonism. It has shown potential benefits in bio-remediation against several strains of plant pathogens.
