Background
The pale cyst nematode, Globodera pallida, is a major pest of potato crops in cool-temperate areas. It primarily affects plants within the potato family including tomatoes, eggplants, and some weeds. If left uncontrolled, pale cyst nematodes can cause up to 80 percent yield loss in potato fields.
