Bio-control of Wilt of Albizzia lebbek by using AM Fungi and Trichoderma viride

The interaction between two arbuscular mycorrhizal fungi i.e. Glomus mosseae and Acaulospora laevis and a known bio-control agent, Trichoderma viride in relation to disease control and plant growth in Albizzia lebbek was studied. Maximum % seed germination (89.6±1.5) and minimum % disease infection (8.9±1.90) was recorded in seeds treated with Fusarium oxysporum + T. viride + A. laevis + Rhizobium leguminosarum. All inoculated plants yielded greater biomass as compared to non-mycorrhizal and plants infected with F. oxysporum. Root biomass (4.28±0.15) and shoot biomass (19.51±0.77) were maximum in plants treated with F. oxysporum + T. viride + A. laevis.
