Septoriosis
WHO CAUSES IT?
Septoria sp. It is a genus of phytopathogenic fungi that affects a wide variety of plants. These fungi produce asexual spores called conidia that spread primarily through water and wind. Conidia germinate on the surface of leaves when they encounter favorable conditions, generally high humidity and moderate temperatures. Once on the leaf, the fungus penetrates the leaf tissue and begins to develop, forming structures known as pycnidia, which are visible as black dots on leaf lesions. These pycnidia release new conidia, which can infect other parts of the plant or be transported to neighboring plants. The fungus can survive in infected plant remains, allowing its persistence from one season to the next.

- Small, round brown or black Taches on the leaves.
- Dark edges around the stains.
- Black dots (pycnidia) in the center of the Taches.
- Premature defoliation of plants.
- Reduction in plant growth and vigor.
- Loss of yield in affected crops.
- General deterioration of plant health.
