Root rot disease, caused by the fungus Fusarium solani is an important soil-borne disease reducing common bean (Phaseolus vulgaris L.) production yields at up to 84%. The present study aimed at investigating the promotion of common bean seed germination and plant growth, and the biocontrol potential of two endophytic Trichoderma spp. against F. solani. The antagonistic and promotion effects of the endophytic fungi were evaluated by means of in vitro and in vivo experiments
