Exotic Pest Alert: Potato cyst nematodes
Potato cyst nematodes (PCN) are soil-borne microscopic worms which feed on roots of potato plants. Root development and tuber yield is reduced and plant growth is stunted.
The biology and symptoms caused by both species are similar. The occurrence of PCN is related to the presence of a host and not to soil type or soil temperature. PCN is subject to stringent quarantine and regulatory procedures wherever it occurs.
