Bacteriosis
WHO CAUSES IT?
Erwinia sp. and Dickeya sp. They are phytopathogenic bacteria that affect a wide variety of crops, including bananas. These bacteria are opportunistic and enter the plant through wounds, stomata or damaged tissues. Once inside, they colonize the vascular system and internal tissues, releasing pectinolytic enzymes that degrade cell walls and cause tissue breakdown. The multiplication of these bacteria is favored by conditions of high humidity and moderate to high temperatures, which accelerates the process of necrosis and rot. These bacteria can survive in plant debris, soil and water, persisting in the environment until they find a new suitable host. The infection intensifies when there are predisposing factors such as water stress, waterlogged soils or the presence of wounds on the plant.

SYMPTOMS
Watery pseudostem rot or soft rot seriously affects the structure of the banana tree, weakening its support capacity and causing its collapse. The disease begins with bacterial infiltration into the internal tissues, where a progressive degradation of the pseudostem occurs. As the infection progresses, the tissues decompose into a viscous mass with an unpleasant odor, compromising the functionality of the plant and its production.
- Appearance of watery areas at the base of the pseudostem.
- Progressive softening of internal tissues.
- Emission of a characteristic foul odor due to bacterial decomposition.
- Wilting and collapse of the pseudostem.
- Secretion of bacterial exudates in the affected area.
- Internal rot that advances to affect the corm.
- Loss of structure and fall of the plant in advanced stages.
