Abstract

Effect of arbuscular mycorrhizal fungi in the management of black bundle disease of maize caused by Cephalosporium acremonium.

Abstract

Three species of arbuscular mycorrhizal fungi (Glomus fasiculatum, Glomus mossae and Acaulispora laevis) were used as bio-agents to manage black bundle disease of maize caused by C. acremonium. The results revealed that colonization of arbuscular mycorrhizal fungi in root system of the host reduce the percentage of disease incidence considerably. In the pots inoculated with G. fasiculatum no disease incidence (0.0%) was recorded whereas, in the pots inoculated with A. leavis and G. mossae 16.66% of disease incidence was recorded and the pots treated with pathogen shows 66.66% of disease incidence compare to control. Among the three bio-agents, Glomus fasiculatum proved to be more effective in managing the disease followed by G. mossae and A. laevis. In addition, all the three AM fungi enhanced the plant growth when they are used alone as inoculum as compared to dual inoculation with the C. acremonium and overall control. This clearly suggests that, AM fungi if used, can serve dual purpose. It can be used as bio-control agent as it shows negative antagonistic interaction soil borne plant pathogens and used as growth promoter because of the ability to supply macro and micro nutrients to the host plants.
