Singh, Nutan Kaushik & Mahaveer P. SharmaThis chapter reviews the role of fungal-based biostimulants and growth regulators in promoting sustainable agriculture. It discusses the importance of fungi in enhancing nutrient uptake, improving stress tolerance, stimulating plant growth, and inducing disease resistance through bioactive compounds, volatile organic compounds, and secondary metabolites. Various fungal groups such as mycorrhizae, Trichoderma, Aspergillus, Chaetomium, Penicillium, endophytic fungi, and fungal elicitors are discussed with respect to their mechanisms, formulations, regulatory aspects, and applications for improving crop productivity and environmental sustainability.en-USFungal biostimulantsPlant growth regulatorsSustainable agricultureDisease resistanceMycorrhizaeTrichodermaEndophytic fungiBiofertilizersPlant–microbe interactionsStress toleranceBook chapter
