The experiment was carried out in the fields of the College of Agriculture, University of Tikrit, where evaluated the efficiency of five isolates of mycorrhizal fungi (Glomus mosseae, Glomus intaticum, ,Glomus fasciculatum ,Scutllospora و Gigaspore margirita) in resisting the white rot disease sclerotia on eggplant caused by the fungus Sclerotinia sclerotiorum, The isolates were activated by growing them in pots with onion roots to produce the primary inoculums, The soil containing the activated primary inoculum was taken with infected onion roots and added to the soil in pots, and the eggplant plant was planted, To study the effect of this inoculation in inhibiting the pathogen and stimulating the growth of eggplant plant, Gigaspore marsirita Isolate superiority was had the highest percentage of infection with mycorrhizal fungal filaments, which was 80%, In terms of dry and fresh weight, the Glomus mosseae isolate superiority with 23.41 and 200.62 grams, respectively, superiority the Glomus mosseae isolate in the  reducing the percentage and severity of the infection, and it was 21.42 and 11.7%. also the same Glomus mosseae isolate was superiority in phosphorous percentage 0.49 mg/g. while the comparison treatment recorded 0.23 mg / g. In the amount of zinc, it was 82 mg/ kg-1 for Glomus mosseae, while the control treatment reached 37 mg/ kg-1
