Fusarium oxysporum f. sp. cubense (Foc) poses a significant threat to global banana production. This systematic review updates current knowledge on the efficacy of various antagonistic microorganisms in controlling Foc, considering recent spread this disease new regions. The studies were systematically analyzed, focusing methodologies, results, and conclusions provide comprehensive overview research its practical implications. A total 118 reviewed, covering use such as Trichoderma spp., Bacillus Streptomyces Pseudomonas both pure cultures consortia. Most focused Foc TR4 Cavendish subgroup bananas originated from Asia. Microbial consortia demonstrated higher control percentage with lower variability, particularly genera Pseudomonas. In contrast, more commonly used for Streptomyces. choice between depends genus experimental context, each approach has distinct advantages. Although reviewed generally high quality, long-term is still lacking. Antagonistic represent promising alternative control, although their specific strain environmental conditions. It been observed that inoculating these onto seedlings before transplantation or combination organic matter enhances effectiveness. Localized testing formulation optimization are recommended improve application preventive suppressive tools soil against infections. highlights vast diversity microbial agents rates, modes action, additional benefits plant development beyond biocontrol. Furthermore, some achieved 100% at level under controlled These findings demonstrate biological viable integrated management.
