Endophytic fungi associated with soybean plants and their antagonistic activity against Rhizoctonia solani

Abstract Background Fungal endophytes produce many secondary metabolites that can reduce root rot diseases. Soybean is a particularly important crop worldwide. Endophytic fungi be isolated, identified, and incorporated into sustainable agriculture for the biological control of Results The aim this study was to isolate some endophytic controlling most diseases soybean plants mechanisms underlying biocontrol regarding suppression pathogens. Ten were isolated from plants. Among them, 3 isolates exhibited high percentage antagonistic activity against Rhizoctonia solani , causal pathogen disease plants, identified as Trichoderma longibrachiatum S12, T. asperellum S11, atroviride PHYTAT7. had ability pectinase chitinase solubilize phosphors. Moreover, they produced siderophores indole acetic acid (IAA), which have strong effect on growth reduced severity by 64, 60, 55%, respectively than infected control. Conclusion results suggest certain associated with potential management in soybean. these considered having growth-promoting
