Pathogen:
Bacteriosis
WHO CAUSES IT?
The pathogens Xanthomonas sp. and Pseudomonas sp. are bacteria that cause diseases known as bacteriosis in a wide variety of plants. These bacteria are found in soil, water and on the surface of plants. They begin their infectious cycle by entering the plant through wounds, stomata or hydathodes. Once inside, they multiply in the intercellular space and produce enzymes that break down cell walls, causing necrosis and other damage to plant tissues. These bacteria can survive on plant debris, contaminated seeds and in soil, facilitating reinfection in the following growing season. Dispersion occurs through irrigation water, rain splash, wind, insects and contaminated tools. In addition, certain species can form biofilms that protect them from adverse conditions and phytosanitary treatments.

SYMPTOMS
The disease caused by Xanthomonas sp. and Pseudomonas sp. in plants it manifests with symptoms that significantly affect the health and productivity of the plants. These bacteria cause leaf Taches, cankers on stems and fruits, and root rot. The initial infection usually begins as small watery Taches that expand and necrotize, developing into dark brown or black Taches with yellow halos. In severe infections, they can lead to defoliation, reduced growth and, in extreme cases, plant death.
- Watery Taches on leaves that expand and necrotize.
- Yellow halos around the Taches.
- Cankers on stems and fruits.
- Root rot.
- Premature defoliation.
- Reduction of plant growth.
- Wilting and collapse of the plant.
- Death of the plant in severe infections.
