Trichoderma harzianum and Trichoderma viride, which were grown on modified media of rice straw waste, were used as suitable natural media for determining the population of the bioagents and stimulating the production of antimicrobial substances, i.e. toxins, enzymes at different periods (1, 2, 3, 4, 5 and 6 weeks). Also, the evaluation of synergistic effect between biocontrol fungi and bacteria may play a key role in the natural process of biocontrol. Synergism can occur when different agents are applied together and cell wall degrading enzymes produced by fungi can increase the efficacy of bacteria. The evaluation of the bioagents formulated on rice straw waste has influenced the percentage of infection of root rot on bean plants under green house and field conditions. The formulation of the Trichoderma spp. to reduce the incidence of the diseases caused by soil-borne fungi in the field has great importance in the biocontrol of the diseases. This work was aimed to determine and improve the efficacy of application and formulation of Trichoderma spp. on the rice straw waste against root-rot disease of bean under green house and field conditions.
