Globodera is a genus of plant-parasitic nematodes, commonly known as potato cyst nematodes. These microscopic roundworms primarily affect potato and tomato crops, leading to significant agricultural losses. They invade the roots of these plants, causing stunted growth and reduced yields. There are two main species of Globodera: Globodera rostochiensis and Globodera pallida. Both species are known for forming cysts, which contain eggs and can survive in the soil for many years. Effective management strategies are essential to control their spread and minimize damage to affected crops.
