Abstract
Banana (<italic>Musa</italic> spp.) holds immense significance on both global and local scales as a source of nutrition, economic stability, environmental stability, and cultural significance. However, plant diseases have greatly impacted the overall production and yield of banana plantations, specifically, diseases caused by fungi. This paper explored the Sigatoka leaf spot complex, its associated fungi, factors that influence disease incidence and spread, and management measures of this disease. The Black Sigatoka is identified as the greatest threat due to its wide-ranging impact on banana cultivars. Further endangering banana production is disease dissemination through wind, rain, and ascospores. Here we emphasized the significance of in-depth comprehension of disease characteristics and progression stages, crucial for devising effective management strategies and safeguarding sustainable banana farming. This paper presented knowledge gaps and challenges in the control and management of the Sigatoka complex. This includes emerging fungicide resistance, sustainable disease management, integrated disease management, monitoring and early detection, international collaboration, climate change impacts, and education and extension services. To fill knowledge gaps and overcome challenges, collaboration among researchers, industry players, government bodies, and international organizations is essential, prioritizing research and outreach to advance sustainable disease management for the global banana industry, mindful of ecological and economic consequences.
