In this study, the effects of mycorrhizal fungi Glomus intraradices, Glomus mosseae and Glomus rubi, which are important members of the rhizosphere microflora and have biological control against plant diseases, were examined against R. solani. For this purpose, the mycorrhizal fungi were extended to corn roots. Then the effect of these biological factors on plant indicators and the severity of R. solani fungus damage on bean plants in greenhouse conditions was evaluated in a completely randomised design with nine treatments and four replications. The results suggest that arbuscular mycorrhizal compounds significantly reduce root rot disease in beans. So the best treatment for increasing plant indices were all treatments containing G. mosseae and the combination of all biological agents treatment. The combination of all biological agents treatment, with 39.50% incidence, 36.25% severity and 53% disease control, had the greatest biocontrol effects on the disease. The study findings indicate that effective combinations of these biocontrol agents can facilitate plant growth and health.
