Book excerpt: Soilborne diseases result in tremendous economic losses of agricultural production and many of the diseases cannot be controlled effectively by presently accepted chemical prevention practices. Hence, scientific research is required to achieve alternatives to chemical methods. Biocontrol strategies including the application of plant growth-promoting rhizobacteria (PGPR) could be a promising alternative. Arbuscular mycorrhizal fungi (AMF) are regarded as an important factor for the uptake of phosphorus (P) and other relatively immobile nutrients particularly in low input systems. Furthermore, AMF support healthy growth of plants and are involved in the resistance against toxic elements and in suppression of pathogens. However, mycorrhization with AMF is frequently very limited. Large scale soil inoculation with appropriate AMF is usually not practicable. The application of beneficial PGPRs to improve root infection with indigenous, site adapted AMF might be a promising alternative.
