WHO CAUSES IT?
Globodera rostochiensis and Globodera pallida are parasitic nematodes that affect potato plants and other solanaceous crops. These nematodes reproduce quickly, forming cysts on the roots of the potato that can contain thousands of eggs. The larvae hatch from the cysts and feed on the roots of the potato, causing significant damage to the plant. Nematodes can survive in the soil for many years, even in the absence of their host, making them difficult to control.

SYMPTOMS
The attack of these nematodes on the roots of the potato causes the disease known as potato cyst nematode. Nematodes cause nodule formation and root damage, which affects the plant's ability to absorb water and nutrients. These damages result in limited growth, wilted leaves, and a significant reduction in tuber quality and quantity.
• Formation of nodules on the roots of the potato.
• Yellowed or wilted leaves.
• Decrease in the quality and quantity of tubers.
• Reduction in plant growth and development.
