The efficiency of arbuscular mycorrhizal (AM) fungi (Giomus mosseae, G. monosporum and Gigaspora margarita) to suppress root rot disease in pea (Pisum sativum) caused by Fusarium sofanf was assessed by comparing the growth parameters of plants infested with F. sofam‘ in the presence or absence of a systemic fungicide application. At plant vegetative, flowering and maturity stages. F. sofanf significantly reduced shoot and dry weights, pod numbers and seed weight of pea plants at all stages of plant growth. in contrast, the growth response and biomass of pea plants inoculated with mycorrhizal fungi was significantly higher than that of non- mycorrhizal plants both in the presence or absence of the pathogen or fungicide. in this connection, AM fungi led to enhancing and increase the content of phosphorus, photosynthetic pigments (chlorophyll, a, b and carotenoids), total nitrogen, phenol and proline contents in the pea plants compared with non-mycorrhizal pea plants. The results suggested that AM fungi is a potentially effective protection agents against F. sofani.
