The effect of interactions between soil borne pathogen, Phytophthora infestans the antagonistic organism Trichoderma viride and Arbuscular mycorrhizal Glomus etunicatum on growth and disease severity of pepper Capsicum annum was investigated in a greenhouse experiment. Pepper seedlings inoculated with the pathogen alone had sever disease symptoms. While those inoculated with mycorrhizal alone had the highest flowering and fruiting values, followed by the pepper seedlings inoculated with Trichoderma viride. But pepper seedlings simultaneously or dually inoculated with the three microorganisms also had good growth parameters, such as early and high flowering incidence, fruit maturity increase in leaf number, height and growth, while the effect of the pathogen was highly suppressed.
