Descrição da doença
Beet necrotic yellow vein virus (BNYVV) is a pathogenic virus that causes the disease known as rhizomania in sugar beet. The virus is transmitted by the soil protist Polymyxa betae, a parasite that infects plant roots. Once Polymyxa betae ingests the viral particles, they replicate within the vector and are released into the soil along with the zoosporangia. Upon germination, zoosporangia release zoospores that swim to the roots of the beet, where they infect the root cells. The virus replicates within infected cells, causing disruption of vascular tissues and leading to the development of characteristic symptoms. The presence of BNYVV in soil can persist for many years due to the ability of Polymyxa betae to form resistance structures (cystosores) that harbor the virus, allowing its re-emergence in successive crops.

Descrição do patógeno
Rhizomania severely affects the growth and yield of sugar beet. Symptoms manifest mainly in the root system and foliage, affecting the plant's ability to absorb water and nutrients, leading to a notable reduction in sugar production.
- Yellowing of the youngest leaves.
- Development of fine roots and proliferation of lateral roots.
- Decomposition and necrosis of the main roots.
- Dwarfism and general reduction in plant vigor.
- Deformation and malformation of the roots.
- Significant decrease in the sugar content of the roots.

Recomendações
- Use sugar beet varieties resistant to BNYVV.
- Implement crop rotation practices to reduce pathogen pressure in the soil.
- Maintain good soil drainage to avoid the accumulation of excessive moisture.
- Control weeds and other alternative hosts that may harbor Polymyxa betae.
- Perform soil analysis to detect the presence of Polymyxa betae before planting.
- Apply chemical treatments to the soil, such as specific fungicides, following technical recommendations.
- Regularly monitor crops to detect rhizomania symptoms early.
- Implement agricultural hygiene measures, such as disinfection of equipment and machinery, to prevent the spread of the pathogen.

There are no treatments for this disease. Treatments are directed at the insect vectors that transmit it. See insect treatments.
RECOMMANDATIONS
- 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.
