Summary
This narrative review examines the role of microbial consortia—combinations of multiple fungal and bacterial species or strains—as biological products in modern agriculture. The authors synthesise evidence on their application as biopesticides and biostimulants/biofertilisers, highlighting mechanisms through which consortia enhance plant health directly and indirectly. The review evaluates real-world successes and failures, discusses evaluation methodologies, and addresses practical challenges in selection, production, and application, offering insights into current and future prospects for consortia-based agricultural inputs.
UK applicability
Microbial consortia products have potential application within UK regenerative and organic farming systems as alternatives to synthetic agrochemicals, particularly for integrated pest management and nutrient cycling. However, UK-specific field validation and regulatory approval pathways would be necessary before widespread adoption.
Key measures
Efficacy of microbial consortia in disease and pest management; plant growth promotion; abiotic and biotic stress mitigation; methodologies for evaluating microbial interactions
Outcomes reported
The review examined the efficacy of microbial consortia as biopesticides and biostimulants/biofertilisers, evaluating their capacity to manage plant diseases and pests whilst promoting plant growth and stress mitigation. It synthesised evidence on selection, production, and application methodologies alongside real-world examples of success and failure.
