WHO CAUSES IT?

Alternaria tenuis is a phytopathogenic fungus that affects a variety of crops, including beet. This fungus produces conidial spores that are dispersed mainly by wind and rain. These spores can remain viable in soil and crop residues for long periods. Infection begins when spores germinate in favorable conditions of high humidity and moderate temperatures, penetrating plant tissues through stomata or wounds. The fungus develops a mycelium that spreads between the host's cells, producing toxins that break down the plant's tissues. As the infection progresses, the fungus continues to produce spores that are released and dispersed to initiate new infections.

SYMPTOMS

Alternariosis caused by Alternaria tenuis in beet is characterized by the appearance of dark Taches on the leaves, which gradually enlarge and become necrotic. These Taches can coalesce, resulting in premature defoliation that affects photosynthesis and, therefore, plant growth and yield. Severely affected plants may show symptoms of wilting and poor overall development, compromising the quality and quantity of the harvest.

- Dark Taches on the leaves.
- Necrotic lesions that enlarge.
- Coalescence of stains.
- Premature defoliation.
- Reduction of photosynthesis.
- Wilting and poor development of the plant.
