The Potato Cyst Nematode (PCN) is a microscopic roundworm that primarily affects potato crops. It belongs to the genus Globodera and can cause significant damage by feeding on the roots of the plants, leading to reduced yields and poor-quality tubers. There are two main species: Globodera rostochiensis and Globodera pallida. PCN is spread through contaminated soil, seed potatoes, and farming equipment. Effective management strategies include crop rotation, resistant potato varieties, and soil testing to monitor nematode populations. Controlling PCN is essential for maintaining healthy potato production and protecting agricultural economies.
