ABSTRACT = {Chili pepper is one of the main crops of economic importance in Mexico, and <i>Fusarium</i> wilting is a disease that limits its production. In addition, the inappropriate use of agrochemicals in farming activities generate environmental and health problems. Therefore, in this study the effectiveness of <i>Streptomyces</i> sp PRIO41 was evaluated as a (1) biocontrol agent of <i>Fusarium</i> spp and (2) plant growth promoter bacteria. Assays of pathogenicity and virulence of <i>Fusarium</i> spp. in jalapeño pepper seeds, and interactions of these pathogens with <i>Streptomyces</i> PRIO41 were evaluated under two nutritional conditions. In the greenhouse, the effectiveness of <i>Streptomyces</i> sp. PRIO41 was determined as a (1) biocontrol of <i>Fusarium</i>, and (2) plant growth promoter of wilt of pepper plants. The results showed that all fungal isolates caused symptoms in pepper seeds and seedlings with different degrees of virulence. Interactions <i>in vitro</i> showed that <i>Streptomyces</i> showed the most effective range of virulence against <i>Fusarium</i> isolates in the poor medium (37.6%-100%), with fungicidal effects in some cases. In the greenhouse, <i>Streptomyces</i> PRIO41 reduced <i>Fusarium</i> wilting up to a 40%, and positively affected all vegetative growth parameters, particularly plant height, leaf area, root length, and leaf and root dry biomasses. This study showed the potential of <i>Streptomyces</i> PRIO41 as a biocontrol agent of <i>Fusarium</i> spp., and as a biofertilizer of pepper plants.},
