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

PathogenHostBiocontrol effectReference
Pea plantsBotrytis cinereaStrawberryPfluorescens 122 was effective for the biocontrol of Bcinerea infection with pre- or post-harvest treatment, almost the same as commercial chemical fungicide.
The rhizosphere soil of pulse cropsPenicillium expansumMucor piriformisBotrytis cinereaApplePfluorescens 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 candidumTrichothecium roseumRhizopus oryzaeTomatoDual culture assay revealed that Pfluorescens inhibited the radial growth of GcandidumTroseum and Roryzae. The results in vivo showed that Pfluorescens provided good control (78.1%) of Gcandidum and (82.2%) Roryzae, but not to Troseum.
Academic exchangeSalmonella entericaTomatoPfluorescens 2-79 reduced risk of foodborne diseases caused by Senterica via competitive inhibition.
Laboratory preservationRhizoctonia solaniCottonPfluorescens 2P24 strongly inhibited the growth of Rsolani when cultured with glucose, whereas not with fructose or mannitol culture.
