Studies of the biocontrol efficacy of Pseudomonas fluorescens against different kinds of pathogens

PathogenHostBiocontrol effectReference
Pea plantsBotrytis cinereaStrawberryP. fluorescens 122 was effective for the biocontrol of B. cinerea infection with pre- or post-harvest treatment, almost the same as commercial chemical fungicide.
The rhizosphere soil of pulse cropsPenicillium expansum, Mucor piriformis, Botrytis cinereaAppleP. fluorescens 1-112, 2-28 and 4-6 were highly effective for the inhibition of conidial germination of pathogens (over 90%), while the effect differed with apple varieties and pathogen types.
Tomato growing fieldsGeotrichum candidum, Trichothecium roseum, Rhizopus oryzaeTomatoDual culture assay revealed that P. fluorescens inhibited the radial growth of G. candidum, T. roseum and R. oryzae. The results in vivo showed that P. fluorescens provided good control (78.1%) of G. candidum and (82.2%) R. oryzae, but not to T. roseum.
Academic exchangeSalmonella entericaTomatoP. fluorescens 2-79 reduced risk of foodborne diseases caused by S. enterica via competitive inhibition.
Laboratory preservationRhizoctonia solaniCottonP. fluorescens 2P24 strongly inhibited the growth of R. solani when cultured with glucose, whereas not with fructose or mannitol culture.
