Background/Objectives: Arbuscular mycorrhiza is a symbiosis between plants and glomeromycota fungi. This relationship gives several important benefits to the plants including increasement tolerance against abiotic and biotic stresses. Methods/Statistical Analysis: In this study, the effects of Plant Growth Promoting Rhizobacterium (PGPR) and chemical chelating factors (EDTA, EDDHA) in the presence of Rhizoctonia solani AG3 were studied on mycorrhizal colonization on potato. To investigate the mycorrhizal colonization percentage, ischolar_main staining was performed. The existence of hyphae, vesicle and arbuscule estimate as Arbuscular mycorrhiza colonization. Findings: The results revealed that interaction of chelating factor of iron (EDTA and EDDHA) mycorrhizal colonization and bacterial strains had positive effects on ischolar_main colonization and in consequence leads to increase fresh and dry weight, other growth factors and chlorophyll. Application/Improvements: It is concluded that combinations of chelating agents (EDTA and EDDHA) may increase the growth and resistance to soil borne pathogens.
