Occurrence and molecular characterization of cyst nematode species (Globodera spp.) associated with potato crops in Colombia.

Potato cyst nematodes (PCN) from the genus Globodera spp. cause major losses in the potato (Solanum tuberosum) industry worldwide. Despite their importance, at present little is known about the status of this plant pathogen in cultivated potatoes in Colombia. In this study, a total of 589 samples co...
