WHO CAUSES IT?
Nematodes are microscopic organisms that belong to the phylum Nematoda. These soil parasites can attack a variety of plants, including beets. Their life cycle begins when the eggs hatch in the soil, releasing larvae that search for roots of host plants. The larvae penetrate the roots, where they feed and develop, causing damage to plant tissues. As they grow, the larvae go through several stages of development until they reach maturity, at which point they reproduce. Females lay their eggs in the roots or surrounding soil, perpetuating the infestation. Nematodes can survive in the soil for long periods in the egg state, allowing them to persist even in the absence of host plants. The ability of these organisms to infest a wide range of plants and their resistance to adverse conditions makes them a significant threat to crops.

SYMPTOMS
The presence of nematodes in beets causes a disease that seriously affects plant growth and production. Nematodes feed on roots, causing lesions and disturbing the absorption of water and nutrients. This results in a series of symptoms that affect both the aerial and underground parts of the plant, compromising its vigor and performance.
- Swollen or deformed roots
- Discoloration and necrosis of the roots
- Reduction in the size and weight of roots
- Yellowing of the leaves
- Leaf wilting and chlorosis
- Delayed growth
- Lower harvest yield
