Ustilaginoidella oedipigera is a phytopathogenic fungus that attacks various species of musaceae, causing severe deformations in the affected tissues. It develops mainly in warm and humid climates, where its spores find optimal conditions for germination. Its infectious cycle begins with the production of spores that can be transported by wind, water and contaminated materials. Once in contact with plant tissue, they germinate and penetrate through wounds or stomata, colonizing internal tissues. As the fungus progresses, it induces abnormal cell growth, causing hypertrophy and characteristic malformations. The proliferation of mycelium within plant tissues triggers the accumulation of toxic substances that alter the normal development of the plant. Under favorable conditions, the fungus completes its development and releases new spores into the environment, ensuring its dispersion and persistence in the environment. It can survive in plant residues and soil for long periods, allowing new infections in subsequent seasons.
