How to recognize and combat moko or maduraviche in banana plantations

In banana trees, Ralstonia solanacearum causes the disease known as moko or matureviche, one of the most devastating for this crop. The infection begins in the roots and spreads rapidly through the vascular system, affecting the flow of water and nutrients. Diseased plants show progressive wilting that begins in the lower leaves and extends to the upper part, accompanied by necrosis in the petioles and bacterial exudates in the conducting vessels. As the disease progresses, internal and external changes are observed in the plant, which seriously compromises the production and quality of the fruit.

- Irreversible wilting of the leaves, which begins at the margins and advances towards the center.
- Yellowing of the lower leaves, followed by their collapse.
- Necrotic lesions on the petioles and pseudostem.
- Bacterial exudates in the cuts of the affected tissues.
- Easy detachment of leaves due to internal destruction of tissues.
- In fruits, appearance of dark spots and pulp with a watery appearance.
- Foul smell in the affected area when making cuts on the plant.
