WHO CAUSES IT?
Phoma betae (Pleospora betae) is a phytopathogenic fungus that mainly affects beets. This fungus reproduces through asexual spores (conidia) and sexual spores (ascospores). Conidia form in structures called pycnidia, which are black, spherical fruiting bodies that appear in infected plant tissue. During wet conditions, conidia are released and dispersed by water and wind, infecting new plants. Ascospores are produced in structures called pseudothecia, which also form in dead plant tissue. These spores can survive on crop residues in the soil, facilitating reinfection in the following growing season. The fungus penetrates plants through wounds or natural openings, and once inside, it colonizes the internal tissue, producing toxins and enzymes that degrade plant cells.

SYMPTOMS
Phomosis, caused by Phoma betae, is a disease that severely affects beets, compromising their quality and yield. The first symptoms are seen as small dark Taches on the leaves and crown of the plant. These Taches expand and become necrotic, causing sunken, discolored lesions. The infection extends to the roots, where black or brown Taches can be seen, which deepen and cause internal rot. Infected plants show delayed growth and wilting, especially in high humidity conditions.
- Small dark Taches on the leaves and crown
