Sclerotinia sp., also known as white rot, is a phytopathogenic fungus that affects a wide variety of plants, including ornamental and garden plants. This pathogen produces sclerotia, resistance structures that can survive in the soil for long periods of time, facilitating plant reinfection.
SYMPTOMS
The disease caused by Sclerotinia sp. In ornamental and garden plants it is mainly manifested by the presence of watery and soft Taches on the leaves, stems and flowers. These Taches can spread rapidly, acquiring a whitish color and cottony texture, resulting in decomposition of plant tissues. In addition, white sclerotia can be observed near the affected areas.
TEMPERATURE AND HUMIDITY
15°C - 25°C
70% - 90%
HOW IS IT SPREAD?
Direct contact with infected sclerotia, spread by contaminated irrigation water, dispersion by wind.

To prevent and control white rot, it is recommended to practice proper crop rotation to reduce the accumulation of sclerotia in the soil. In addition, it is important to avoid excess watering and maintain good air circulation around the plants to reduce ambient humidity. The use of specific fungicides may be necessary in cases of severe infections.
