    'Staff publications' is the digital repository of Wageningen University & Research

    'Staff publications' contains references to publications authored by Wageningen University staff from 1976 onward.

    Publications authored by the staff of the Research Institutes are available from 1995 onwards.

    Full text documents are added when available. The database is updated daily and currently holds about 240,000 items, of which 72,000 in open access.

    We have a manual that explains all the features

Abstract Mycorrhizal fungi are mainly known for supporting phosphorous uptake by plants, whereas Pseudomonas species are often selected as biocontrol strains. However, both microbial groups have also other mode of actions.
Our research showed that by inoculating peat substrate with the mycorrhizal fungus Rhizophagus irregularis strawberry roots were colonized by mycorrhiza, which was not the case in non‐inoculated peat substrate. These mycorrhiza‐colonized strawberry plants showed significantly reduced Phythophthora
cactorum infections. An antagonistic Pseudomonas chloraraphis strain was selected for its phosphorous (P) mobilisation capacity.
In greenhouse assays, this strain elevated P levels in young tomato plants, and infection due to Pythium aphanidermatum was repeatedly reduced.
These two examples demonstrate the multiple mode of actions of one fungal and one bacterial inoculant, both combining P mobilisation and biocontrol of plant pathogens
