WHO CAUSES IT?
Ramularia betícola is a phytopathogenic fungus that mainly affects beets. This fungus produces conidial spores that are spread through wind, water, and contaminated tools. Spore germination occurs under conditions of high humidity and moderate temperatures. Once the spores germinate, the fungus penetrates the plant tissues, mainly through stomata and wounds. Inside the plant, the fungus develops intercellular mycelium and produces new spores in infected tissues, thus perpetuating its spread and the infection cycle. The fungus can survive in the remains of infected plants and in the soil, which facilitates its persistence and reappearance in subsequent crops.

SYMPTOMS
Ramularia caused by Ramularia betícola significantly affects beets, manifesting first in the lower leaves and progressing to the upper ones. Early signs include small chlorotic Taches that develop into dark brown necrotic lesions, surrounded by a yellow halo. These lesions can coalesce, causing significant defoliation and reducing photosynthesis and crop yield. Under severe conditions, plants may experience widespread wilting and premature death.
- Small chlorotic Taches on the leaves.
- Dark brown necrotic lesions with a yellow halo.
- Coalescence of lesions causing defoliation.
- Reduction of photosynthesis.
- Generalized wilting.
- Premature death of the plant.

RECOMMENDATIONS
- Check the back of the leaves frequently, especially in dry weather.
- Spray water on the leaves to increase humidity and prevent them from settling.
- Keep plants healthy with good watering and adequate light.
- If you see cobwebs or damage, clean the leaves with a damp cloth or pressurized water.
- Use potassium soap or neem oil every few days until they disappear.
